Cooperative Learning Groups & Responsibilities

Task A: Triangle Sort1. Sort the entire collection into three

groups so that no triangle belongs to two groups.

2. Give a description or name to each of the groups and record on chart paper.

3. Once you have found one criterion for sorting. Determine a second.

Cooperative Learning Groups & Responsibilities

Task 1: Classifying TrianglesThe following shows how triangles can be classified according to some of their features: ANGLES, SIDES, SIZE

Engage/Activate!

Individual Activity.OSketch a triangle

in each of the nine cells.

OOf the nine cells in the chart, two of them are impossible to fill. Can you tell which ones and why?

Reflect and Connect!

Question to Help Student’s Share Their

Feelings

What was easy/difficult for

you?

How did solving this

problem make you feel?

Do you feel ready to solve

a problem like this again?

Question to Help Student’s Reflect

What did you do well?

What difficulties did

you have?

What did you learn by

solving this problem?

Conclusion

The aim is to encourage children to think critically about solutions rather

than focus on one “right” answer.
