Origami in the Geometry Classroom

 

Disclosure: I was sent these packages of origami paper in exchange for an honest review. All opinions are my own.

Last week was a stressful and emotional week at school and home, so I wasn't able to post. I have realized when I'm not in the right mindset my reviews are hard to write. For a while I have wanted to share some ideas I use in my geometry class with origami paper. I will be sharing four new packages of origami paper with you in this post. I keep a box of origami paper in my classroom and students come and get some when they are feeling creative or need to relax. I also use it in my geometry class. I have the kids do a project using geometric terms project using geometric terms, but I also use it for some easy discovery and illustrating properties. I have been wanting to share these ideas with you. May is the perfect time to introduce it since origami is a Japanese art form and ties into Asian American and Pacific Islander Heritage Month.

Math Monday -- Parent Graph Transformations Lessons

 

The start of this year is tough. My schedule is tough. I teach straight through on Mondays, Wednesdays and Fridays with only lunch as a break. I have two prep periods on Tuesdays and Thursdays, but they are usually spent giving extra help to students. Our school requires teachers to be there from 7:30 to 4. School goes from 8:15 to 3:15. I have to say the extra time until 4 is a waste for me because my brain just needs a break before I can really think or function on work. I often have to wait until after dinner to get any more work done. As a teacher I feel it is a little ridiculous for any school to have set hours for teachers besides the required ones when the school is open. Teachers by nature will do the work they need to on their own time. We are not teaching because we want to be rich or famous. We teach because we want to teach and be with the kids. After three weeks in, I'm still getting use to the schedule and figuring things out.

Not-So-Common Cents -- Blog Tour & Giveaway

Disclosure: I was sent a copy of this book in exchange for an honest review and being part of the blog tour & giveaway. All opinions are my own.

Today I get to share with you a new National Geographic Kids book all about money and our financial system. I am participating in the Not-So-Common Cents Blog Tour & Giveaway which includes an excerpt from the book. See below the blog tour banner! It also includes a giveaway--good luck! The book is Not-So-Common Cents by Sarah Wassner Flynn. It is recommended for ages 8 to 12.

Fractal Tree -- Geometry Class Project

 

One of my goals this year is to bring fractals into my teaching, especially in geometry class. Today I am going to share the fractal tree. It can easily be done on a computer but is also great for practicing measuring with a ruler and protractor. Now a fractal tree is probably one of the most basic fractals and well-known or at least its cousin, the fern is certainly seen as a fractal. 

Geometric Origami Project -- Origami Bunny Balloon Tutorial with Geometry Terms

 

In geometry class we have been talking about the special segments in triangles. It is the perfect time to introduce my origami project. To start I shared a tutorial with them making an origami bunny balloon. I use terms from our lessons like median, midsegment, angle bisector and more throughout the tutorial. The kids make one with me in class. Then I give them my assignment. The kids enjoyed spending the class trying different origami projects. You can watch my tutorial here. I love that I am making an origami bunny balloon when lunar new year is going on and it is the year of the rabbit in Chinese Horoscope. 

Congruent Triangle Gazebo -- Geometry Class Project

 

One of my goals now that I'm teaching is to share some of the projects I am doing with my classes. Before break I was teaching my geometry classes the congruent triangle shortcuts: SSS, SAS, SAA, ASA, and HL (for right triangles only). In one class I assigned a congruent triangle project. I gave the kids the choice of building a truss bridge, making a gazebo, or making a congruent triangle picture that had at least five different pairs of congruent triangles (one for each shortcut) and they needed a page showing each of the pairs as congruent with one of the shortcuts or needed to mark them in their drawing. Most of the kids picked the drawing. I wasn't in love with the gazebo tutorial, or the gazebo made in it so I thought I would make my own. Today I am going to share my gazebo as well as a project sheet to assign it. (I am still deciding if I am going to assign it to my other class or not as they are about half a chapter behind the other one.) 

Dollhouse Scaling Project -- Geometry Class Project

 

This weekend I found a mini-room box kit on clearance at a craft store. I picked it up and thought it would be great for my classroom when I teach ratios, similarity and scaling. It is 1/24-scale which is also known as 1/2 scale. The 1/24 scale means that for every 24 inches (or 2 feet) an object is in real life, the miniature will have 1-inch. All the dollhouses I have worked with previously have been 1/12 scale or sometimes called 1:1 scale. It is for every 12 inches (or 1 foot) a real-life object is the miniature will measure 1 inch. The kit was easy to put together though I did mess up the wallpaper on one piece.

Exploring Pi with a Fractal & Pi Activity Round-Up

 

I really wanted to do something with pi for artwork in my classroom plus would love a good pi activity. I struggled with this one. I have seen the pi skyline like this one over at What Do We Do All Day? It is fun but not quite what I am looking for. There are different pi artworks if you google "pi art" but most is based on the digits of pi. To be honest I do not believe in having kids memorize the digits of pi, so much of the artwork is not my thing. As I was searching for ideas, I came across this YouTube video that intrigued me. I decided to make the "fractal" that has an area of pi! It is a spin from the Sierpinski Carpet, Menger Sponge, and the Wallis Sieve. Now fractals are supposed to be infinite, but I cannot draw them this way. I am working on taking this fractal to the third level. If you were able to go on infinitely the area of this picture would be pi. 

Pythagorean Theorem Fun -- DIY Mathematical Art

 

As I continue to think about my new job in September and plan for what I want to hang in my classroom, I am exploring the Pythagorean Theorem. The Pythagorean Theorem is probably one of the most well-known or well-remembered theorem in math. It is often taught in both algebra and geometry. In algebra it lends to working with exponents and roots and in geometry with triangles. I have seen memes saying how people did not use the Pythagorean theorem today, but I have also been told by many people that they have used it in their lives from building a new deck and woodwork to programming and more. Although math has real life applications and was mostly discovered to explain the world, much of math is taught to help develop the brain of our children. In high school the brain is just beginning to truly develop its logic skills and math is huge in helping with this. The Pythagorean theorem also is mentioned (incorrectly) in the Wizard of Oz. Yes, it is this famous!

Although it is named for the Greek mathematician, Pythagoras, it was known throughout the world before his time. It is referenced in Ancient Egypt and Babylon (around 1900 BC). Apparently, it did not become as well known until Pythagoras stated it. There are many proofs of this theorem and some of them like the one below is a visual proof.

Origami for Geometry Class with Marbled Patterns Origami Paper

  

Disclosure: I was sent a pack of this origami paper in exchange for an honest review. All opinions are my own.

As I mentioned I am returning to the high school math classroom in the fall! One of my goals is to bring more hands-on activities as well as projects to the class. One of the classes I am pretty sure I will be teaching is geometry. I am so excited to be back in the geometry classroom. I am hoping to use origami in the classroom and definitely want to have an origami project in the geometry class. This year's teacher did this, so I am working off her idea and adding my own spin. Today I am going to share two origami tutorials all using a beautiful pack of Origami Paper 500 Sheets Marbled Patterns 6-inch paper. This particular pack of paper is being released in July 2022, but there is a similar pack of 200 sheets already available. 

Life According to Og the Frog Review -- Blog Tour

Disclosure: Penguin Kids sent me a copy of this book in exchange for an honest review. All opinions are my own. The links are affiliate links where I will receive a small percentage of any purchases made through them at no cost to you. Thank you for supporting Crafty Moms Share!

Today we get to participate in the blog tour for Betty G. Birney's newest book: Life According to Og the Frog. You may have heard of her other book(s): The World According to Humphrey. She has done a lot more than just one book about Humphrey. I haven't read any of them, but after reading about Og the Frog, I cannot wait to get my hands on them. 

Cinnamon Whoopie Pies

During school vacation week, Hazel and I took a cooking class with her best friend from school and his mother at a place called Play Makers. It is a local place that is run by mothers and offers play times, cooking classes as well as art classes. Her friend's birthday party was at this location in January which was our first exposure to it.

When we got there, we found out we were making whoopie pies. Now Hazel has similar chocolate tastes to me. We love chocolate but do not like chocolate cakes including brownies or even Oreos. While each child was mixing their whoopie pie, the other mother and I were talking about this and she suggested we put in extra vanilla and no cocoa powder. I asked the instructor if this was all right with her and she suggested we add some cinnamon. A new treat was born. I have to admit Hazel was the only child to eat both of her completed whoopie pies during the class (most took at least one of them home). Needless to say it was very tasty. Hazel also informed me that we would have to make them at home. So this week we did. At the class each child got to decorate a copy of the recipe to bring home.

We made two batches, one chocolate and one cinnamon since Steve loves chocolate and chocolate whoopie pies happen to be my father's favorite as well and he was here since he was taking my mother into the hospital for her surgery (all prayers are welcome for her). 

Cinnamon Whoopie Pies

Our recipe:
1/4 cup canola oil
3/4 cup light brown sugar, packed
2 eggs lightly beaten
3/4 cup milk
2 teaspoons vanilla extract
1 teaspoon baking powder
1 teaspoon baking soda
3/4 teaspoon salt
1 1/2 cups whole wheat flour 
2 teaspoons cinnamon (we used 1/4 cup this time and it was too much--the original recipe called for 1/4 cup dark chocolate cocoa powder)

Cream Filling:
4 ounces cream cheese
1 cup confectioner's sugar
1 pint whipping cream
1 teaspoon vanilla
pinch of salt

1) Preaheat oven to 350 degrees.
2) Line two baking sheets with parchment paper.
3) In large bowl mix oil and brown sugar until smooth.
4) Whisk in eggs, milk, vanilla, baking powder, baking soda and salt.
5) Fold in flour and cinnamon. Then drop by the tablespoon into twelve mounds evenly spaced onto each baking sheet. (Ok, with Hazel helping scoop ours were not evenly spaced.) Bake until springy to the touch, about 10 minutes. Transfer to cooling rack to cool completely.

6) Meanwhile, using an electric mixer, beat the filling ingredients until fluffy.
7) Spread the flat side of 12 cakes with the cream cheese filling. Top each with another cake.
8) Optional: Dust with confectioner's sugar. Enjoy!

Chocolate Whoopie Pies

My father tried both kinds and liked them both! Enjoy!!

Exploring at the Wildlife Sanctuary and Painting

On Wednesday we had our class at the Mass Audubon Ipswich River Wildlife Sanctuary. We skipped our class at Drumlin Farm this week since Hazel claimed to feel like she was going to throw up on our way there, however half an hour later she wanted lunch. I'm not really sure what happened, but she seems fine now. Anyway, at the Ipswich River Sanctuary we jumped in puddles and chased the other 3-year olds. Oh, and Hazel made a friend and held hands with her on part of our walk. I took a picture of them, but did not get the mother's permission to post it on line, so I won't. After a short walk we went back to the vernal pool to see if we could see some frogs this time. And we did!! We saw two different ones. The first one pictured above was pretty brave with all the kids around. Then one of them got a bit too close and he jumped in the water, but he stayed where we could see him with his eyes out of the water the entire time.

A little ways down we saw a big bull frog. He had different coloring than the first and was sitting on a log (again until someone got a bit too close).

While checking out the second frog, we saw a fast moving turkey (many of the kids missed it by the pool) and one of the kids found a slug. He even stuck his eyes out for us!

Then it was time to go back to the Nature House for our craft. On our way back through the field we saw the turkey again.

Then for our craft we made bird nests out of air-drying clay and grass. Then the instructor gave us a bird for it.

Then we ran some errands and came home. After lunch we finished our fairy garden and did some painting.

We have been reading the book Brown at the Zoo by Christianne C. Jones. It starts by talking about the colors--primary and secondary and that brown is a tertiary color. It then talks about how you can make it. The book goes through all the things that are brown at the zoo. It is in a series of books about colors. We decided to try to make brown in the different color combinations with Hazel's paints. Basically you can mix the three primary colors or you can mix any two colors that are opposite each other on the color wheel (red and green, yellow and purple, or orange and blue). We tried to make different shades by mixing the different colors. Some combinations worked better than others, but it may be the proportions we (Hazel) used.

Then she wanted to do some more paintings from The Color of Us. So we mixed yellow, white, black, and red in different proportions to explore the colors we would get. I let Hazel have a bit more control with the mixing this time.

Then we started over with some new mixtures and got this.

Then Hazel wanted to paint with blue. She said these were blueberries, but I thought it could also be pictures from The Dot by Peter Reynolds. We kept saying we were going to make some dot paintings, but never quite got to them.

Then she asked to use watercolors and she came up with the following. I think she had blueberries on the mind!

Just a reminder that Sharing Saturday will start tonight and you can visit the wonderful posts shared last week still, and Happy Family Times will end tomorrow, so go link up. And I'm still hosting a link party for Mother's Day gift ideas.

A Morning at Drumlin Farm

Today Hazel and I started a class at Drumlin Farm. Drumlin Farm is a full operating farm run by the Massachusetts Audubon Society. Our class is called Spring Sense-Sations. It is about using your senses around the farm and seeing what senses the animals use. Last year Hazel and I took a course that was for two-year-olds to introduce them to spring at the farm. Hazel was completely afraid of the animals if we got too close. We will see what happens this year.

He greeted us all when we came to the Turkey House

Our class started in the Turkey House. I don't know why it is called the Turkey House, but it is a building with a classroom. And we did see turkeys right outside. Our first adventure was finding the Turkey House since we had not been there before. When we arrived there was a table set up with all sorts of natural things--pine needles, leaves, coyote teeth, nettles, apple slices, etc. for the kids to use their senses with. Then the instructor talked about what our five senses are and then she introduced us to our guests for the day--three mice. We observed them in a somewhat naturally set-up habitat. She pointed out the size of their feet to their ears versus ours. At this point we had to make a bathroom run where we saw all the turkeys since we didn't notice them coming in since our main concern was finding the Turkey House.

The females turkeys the male was trying to impress

While on the bathroom run we saw our teachers from last year so Hazel was excited about that. She had been asking if we would see them. She did not want to stay inside too much and wanted to get out to see the animals. Next our teacher showed the kids how to make newspaper explorer hats--well ok, all the moms made the hats for the kids. Hazel didn't want one, but I made one anyway. Then we headed out to see the animals.

We saw the goats and the kids. Then we saw some chickens. Hazel was terrified of the chickens last year but couldn't wait to see them this year.

Then we looked at the lambs and sheep and headed to the pig barn. (Sorry I didn't get a picture of Hattie, the pig.)

Then we headed to the red barn to see Midnight, the pony, but he wasn't there. We saw the cows instead.

Then we walked on the Discovery Trail and saw the cows up close. On the Discovery Field they also had cement type makers with labeled foot prints--rabbit, fox, raccoon, etc. Then we headed over to see if we could spy the rabbit. We did! At least if we picked the kids up we all did. She is a good hider.

At this point the class was over. So Hazel and I went to check out the fox and then back to see all the animals and take pictures for you.

The fox was rather quick and I didn't get a great picture of him. Then we went back to the goats. There are kids laying where their food is suppose to go.

We went into the goat/sheep shed.

On the sheep side there was a ram and we saw a sheep eating.

Outside we found more sheep and lambs.

Then we headed to the chicken house. It took Hazel the entire class (7 weeks or so) last year to be willing to enter the chicken house. This year she couldn't wait to get in there.

Then we said hi to the pig, but I didn't get a great picture since she moved outside and there wasn't a good angle of her. And we headed back to the red barn and this time Midnight was there as well as another sheep that apparently did not get shaven over the weekend during their big wool shearing festival.

They also have a room set up to explore about horses. We discovered based on Hazel's height she is a pony---10 hands tall.

And she tried to ride a horse as well as groom one.

They also had a table of the sheared sheep's wool out for the kids to feel. It had not been treated or anything.

Then we headed up to bird hill to check out the birds--mostly the owls and hawks. They keep some of the "wild" animals--birds, rabbits, foxes, etc. that were injured or born into captivity and got too use to being cared for to be released safely.

Great Horned Owl

Sorry the hawks came out way too blurry to post and by this time Hazel was tired and getting cranky so we headed home, but not without stopping to buy the last dozen eggs from the farm.

Talk about colored eggs. Check out all the different ones in here.

Of course the view I got most while walking through the farm with Hazel was this:

her back! She was so excited to be back there!
