Identifying Angles of a Triangle: From Worksheet to Models

It all started with a worksheet like this one shown in the picture.  The students were to write in the name of the triangle based on its angles...

But, I changed up the lesson by creating large construction paper triangles that closely resembled each of the shown triangles on the worksheet.

These triangle could be measured, and the group passed each triangle around as we discussed the angles together.

Suddenly, the classification based on angles used in the triangles began to make sense to the dual language students in the small guided math group.  

   It took more work on my part to make the individual triangle models, but the students seemed to understand it more clearly and the discussion from the group was great!

 It was worth my effort.
