Math Monday: Tetrahedron Tree

 "Say 'Tree's'"

Math Monday's theme was introduced with a Tri Triangle Tree.

"Angel"
 
Then I gave Ms. O four triangles, exactly the same size and asked her how many ways she could arrange them.
"Tree"

"The Letter C"
 
"A Boat"


Then, we looked at how four triangles can become a large triangle and that triangle can be folded into a pyramid!
