## Pipe music with decimals

- Secondary Activities
- Number and Algebra
- Level Four

These exercises and activities are for students to use independently of the teacher to practice number properties.

## Base 2 and complementary arithmetic

- Secondary Activities
- Number and Algebra
- Level Five

These exercises, activities and games are designed for students to use independently or in small groups to practise number properties. Some involve investigation (see Related Resources) and may become longer and more involved tasks with subsequent recording/reporting. Typically an exercise is a 10 to 15 minute independent activity. While the involve operating with number, the contexts for the number operations in these exercises are not formally in the curriculum, and are therefore most suitable as ‘broadening’ or extension work with more able students.

## Series-ous Escape

- Secondary Activities
- Number and Algebra
- Level Four

These exercises, activities and games are designed for students to use independently or in small groups to practise number properties. Some involve investigation (Mikes Investigation Sheet link) and may become longer and more involved tasks with subsequent recording/reporting.

## Double Double Boil and Bubble

- Secondary Activities
- Number and Algebra
- Level Four

These exercises, activities and games are designed for students to use independently or in small groups to practise number properties. Some involve investigation and should be formally written up (Investigation Write Up) and may become longer and more involved tasks with subsequent recording/reporting. Typically an exercise is a 10 to 15 minute activity.
