Types of Triangles

Does anyone have any good "tricks" to help the kids remember the difference between an equilateral, scalene, and isosceles triangle? My kids get equilateral because it has the word "equil" in it, but they're having trouble with the other two. We have done songs, poems, practice, but some are still having trouble identifying.

Scalene- ne stands for not equal
Isosceles-2 e's in the word, 2 equal sides

I've never used this, but it just occurred to me:

We have TWO Eyes-- so ISosceles is two!

Also, isosceles has SOS - side/other/side. Two sides the same length.

And scalene - like scale. Each step is different, each side is different.

Maybe you have't reached angles yet, but.....

Acute- it's a cutie! With the little kid voice. My math teacher in high school did that and I never forgot it. Then he did obtuse in a big man voice. It worked.

Register for studyjams.com through scholastic. It says you have to pick a plan but it's actually an unlimited free trial. They have a song on the different types of triangles.

I once did a lesson where we created triangles with straws and twist ties (to connect the ends). They had to cut up the different lengths of the straws to see the difference between the different types.

This may help for those who need a hands on visual.
