This is a follow-up to my paper toy 'ible. I looked for sliceforms on this site and did find a few but not enough. As a geometry teacher of many years, I know how important playing with shapes is to a student's understanding of shapes.

In this instructable, I want to show you how to design and produce a few simple shapes that you can play with afterwards--or share with a child who can play with it. (I gave my paper toy sample to an adult to give to her children. She did show it to them but refused to let them keep it. She loved playing with it too much.)

Once you have built a few of these, you should start to feel capable of trying to design a few of your own. Don't be surprised if they come out nothing like you expected--especially on the first try.

Step 1: Print Some Graph Paper on Cardstock

As with all sliceforms, you need to use something a little thicker than copy paper. I use cardstock because I have a lot of it and it comes in a lot of fun colors. You can use 'cover stock' which is just a little lighter than cardstock. You can use sheet of plastic--but it is hard to print on plastic. Tracing your design onto the plastic with a permanent marker works well. Then you can erase marks left behind with rubbing alcohol.

Print a few sheets of graph paper. I don't bother with just printing a single sheet because when I start playing with my math, I tend to get a little carried away.

There are a lot of graph paper generators available on the internet so if you want a different size grid, you can easily find one.

<p>nice project mrsmerwin..</p>
<p>glad you liked it. Have you tried to build one yet. The long one (rectangular or oval) makes a nice fidget toy.</p>
