Triangles

Earlier this week first graders sorted through a collection of shapes to find all of the triangles.  This can be tricky for students this age, because if the triangle isn't an equilateral triangle, or if it is "upside down", many students will not think that it is a real triangle.  On one side of their paper first graders glued the shapes that they thought were triangles, and on the other side they tried to write 3 different attributes that these triangles all share.
