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.
