Students learn how to calculate square numbers and square roots using visualisation, written and calculator methods.

Less able students are encouraged to use a timetable to support their learning, and more able are challenged to demonstrate Lagrange's Theorem.

**Differentiated Learning Objectives**

- All students should be able to calculate the first twelve square numbers using the timetable grid.
- Most students should be able to calculate the square numbers and their roots up to 12.
- Some students should be able to calculate the square of negative, decimals and fractions.
