Learning Objective

• Identify directed numbers.
• Use directed number line to order numbers.
• Utilize directed numbers in real life situation.
• Work out distance between the numbers.
• Add and subtract directed numbers.

Learning Outcome

• Read and interpret negative and positive numbers in real life situation.
• Read scales with negative and positive numbers.

• Add and subtract directed numbers.

Recommended Level 

This workbook will help pupils to build the knowledge and skills expected to match the new National Curriculum for years 5 and 6. Although, years 7, 8 and 9 can use this workbook a refresher.

The mathematical tasks in directed numbers book 1 are based on the variation theory. These tasks will allow pupils to gain an understanding of both negative and positive numbers. Furthermore, the tasks will explain the rules and give a guidance of how to calculate by using arithmetic operations. Such as, plenty of examples for pupils to learn the rules and internalise the concept.
