Problem: Use a given number of sticks (12, 10, 9 and 6) to make four triangles. A triangle is made using three sticks with the vertices (corners) formed using the dough.

How many different figures comprising of four triangles can be formed using 9 sticks?

In this lesson, we discuss what makes a task a problem. We also learn to analyse a problem if it is suitable for a given age group.

The class was introduced to Polya's problem-solving model.

Problem: How many apples are there on each tray? See previous post.

In discussing this problem, the idea of mathematical modelling was introduced. The term problem-solving heuristics were also explained with several examples.
