What to do

Cut out 6 circles. To make the circles, we traced the bottom of a recycled yogurt container.

Draw a triangle inside one circle. The triangle needs to be equilateral, which means all three sides are equal. We just used a ruler to draw ours, but you can use a compass or protractor to be exact. Obviously, the more equal the sides, the more aligned is the final product.

Cut out the triangle and trace it on the inside of all the remaining circles.

Fold each circle along the triangle’s lines. To make it easier, we lined the triangle line along the edge of the table and then folded.

Time for the gluing fun! Glue one folded circle flap to the flap of another circle. Keep going until all six are connected. Note: if you going after a specific pattern, make sure all the pieces are pointing in the same direction.

Fold all flaps flat in the same direction and let it dry under a heavy book.

You can put it in the envelope and give someone on Valentine’s Day. 

Or you can keep going and turn it into a 3-D Valentine! 

 

3-D Math Valentines

The same idea as above, only now you need 20 circles with equilateral triangles inside of them.

Now glue all 20 triangles together in a ball shape. The easiest way we know to make it look even is to first glue 5 circles together to form a top and another 5 circles to form a bottom. The pic below shows you two views.

Now flip the top over. Do you see five flaps that don’t have anything attached to them?

We think they are absolutely magnificent!

 

These valentines are made from circles and triangles and demonstrate how simple shapes can be joined together to form elaborate designs.

 

Vary the sizes of your finished product by using smaller and larger circles. If you are making a whole bunch of these, you can also buy circle punches to speed up the process.
