Explain how negative numbers are used on a coordinate grid

Maths

Represent a change story using addition and subtraction symbols

Interpret numbers greater than and less than zero in different contexts

Read and write negative numbers

Explain how the value of a number relates to its position from zero

Identify and place negative numbers on a number line

Interpret sets of negative and positive numbers in a range of contexts

Use knowledge of positive and negative numbers to calculate intervals

Use knowledge of positive and negative numbers to interpret graphs

Solve problems involving positive and negative numbers in a range of contexts

In this unit pupils will  interpret numbers greater than and less than zero. They will read and write negative numbers explain, how the value of a number relates to its position from zero positioning on a number line. In the future unit pupils will estimate the value and position of numbers including negative numbers on unmarked or partially marked number lines and calculate intervals across zero.

In the prior unit pupils compared and ordered 4-digit numbers They learned to round and rounded 4-digit numbers to the nearest 1000, 100 and 10, counted backwards through 0. In this unit pupils will interpret numbers greater than and less than zero. They will read and write negative numbers, explain how the value of a number relates to its position from zero, positioning on a number line.

Negative numbers

a set of values that show an exact position

any of 4 areas made when a plane is divided by x and y axes

the x and y lines that cross at right angles to make a grid

Using brackets and a comma, give the coordinates of the cross marked on this two quadrant grid.

positive x direction, positive y direction

negative x direction, positive y direction

negative x direction, negative y direction

positive x direction, negative y direction

Match the letters with the quadrant descriptions.

In which quadrant will you find the coordinate (−2, 5)?

If the axes were extended, in which quadrant would you find the coordinate (18, −25)?

When joined together, the four crosses form a rectangle. Tick all of the coordinates that would be found inside the rectangle.

What are the coordinates being shown here?

It is to the right of −6 on a horizontal number line. 

It is to the left of −6 on a horizontal number line. 

It is to the left of −4 on a horizontal number line. 

Which of the statements about the number −5 are true? Tick all that apply.

3 and −3 have the same distance from zero.

Put the following numbers into descending order. 

There is no number between −10 and −9.

What number is exactly halfway between −10 and −9?
