Number Squares

Working with signs and numbersFunctional skills lesson 2

Aims of the exercise.

• To explore the different numerical functions used in everyday life.

• Work out simple three part calculations.

Exercise 1

• Fill in the grid spaces with the mathematical sign needed to complete the grid.

• The signs used are + - x and ÷

Using Numbers in the Work place.Answer the following questions

1. When would you use :- Addition

Subtraction Multiplication Division In your place of work?

2. What mathematical processes do you need to do to work out how much you will be paid for a weeks work?

Example 1

• Bob is contracted to work for 37 hours a week. Last week he did 43 hours.

• He gets paid £9 per hour with overtime hours paid at 1.5 times the hourly rate.

• How much did Bob get paid last week?

Example 2

• Using your new skills, how much you will be paid for your weeks work?
