Lesson 5: Problem 18

Problem: Make squares using the shapes shown below.

Some squares that we have made,

For a child who cannot see, we can show them an incomplete square like this demonstrated by Dr Yeap in the picture below.

Challenge:

1. Make squares of different sizes. (Promotes a systematic way of doing)

2. Can you make the same size square in all possible ways? (Promotes creative thinking)

Take away from this problem:

- In teaching measurement, we need to identify a unit to compare against it.
- Learning is thinking deeply rather than to gain more information!
