Directed Numbers Book 2

Directed Numbers are numbers with both size and direction; one direction is positive and the other is negative. In mathematics, a negative number represents an opposite. Usually, a negative number is less than zero.

Learning Objective

• Identify the directed numbers.
• Use the number line to order the numbers.
• Add and subtract the directed numbers.
• Multiply and divide the directed numbers.
• Simplify the directed numbers.
• Research use directed numbers in temperature.

Learning Outcome

After working through this workbook the pupil should be able to:

• Add negative and positive numbers using the rules.
• Subtract positive and negative numbers using the rules.
• Multiply and divide positive and negative numbers using the rules.

Recommended Level 

This workbook will help pupils to build the knowledge and skills expected to match the new National Curriculum for years 7. Although, in reality many pupils in years 8 and 9 will benefit from working through this workbook as a refresher.

The mathematical tasks in directed numbers book 2 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.

To conclude, to maximise the benefit for the learners, it is recommended that these workbook should be used from beginning to end.
