There is nothing better than a really good hands on activity in math. It beats worksheets every time. It has taken me several years to figure out how to make hands on learning meaningful, not just hands on activities for the sake of not doing a worksheet.
One thing I’ve tried out is having students make their own tangrams.
The first year I did this, I will not lie to you, it was HAIRY. Really bad. Like…kids cried because they were so lost during the steps. I was running around like a chicken with my head cut off trying to help. It was terrible and I vowed never to do it again. Then YouTube happened to the internet…and my world was opened to the idea of using video to help me teach how to make them. In addition, I have them sit in groups so that they can help each other when they are stuck on a step. Things have improved dramatically.
Here are two videos that I’ve used in the past for my third graders. I personally like the first one better, but it’s a bit long. The second one is short and sweet and to the point.
After we make the tangrams, I have them set all the pieces in front of them and set the timer for five minutes. I tell them that they have five minutes to put them back together into the square they started with. ONE third grader in the last 7 years has been able to do it in five minutes! Of course every year it is very dramatic since hardly anyone belongs to that Hall of Fame. When I start the timer the room becomes so silent, you could hear a pin drop. It is instant engagement.
My favorite part is that during the process of making them, they find shapes they know and you hear them shout things like “trapezoid!”, or “parallelogram!”. This all leads perfectly to the next activity, which I will talk about in my next blog post where I take them a bit deeper.
Love it! We’ve been working with Pentominoes in my class (just printed on card stock) and it has been really challenging and fun.
[…] looking for ways to have students apply the vocabulary to new situations. After learning how to make our own tangrams yesterday, we took it to another level today. We decided to sort and classify the shapes that make […]
Thanks! I knew you could make them but never really looked up the ‘how to’.
Great activity. Children learn best when they get to figure things out themselves. I love that they get to name each polygon as they cut it and even have discussions about them.
