An integer is any positive or negative whole number or zero.

Plotting non-integer coordinates

Maths

In this unit, pupils extend their knowledge of plotting coordinates from KS2 by now plotting non-integer values. Pupils learn that a set of points can satisfy a relationship and this understanding is built on in the sequences unit

In this unit, pupils learnt how to plot coordinates in all four quadrants via plotting positions and then shapes

Plotting coordinates

Coordinates can take integer values such as $$(2,5)$$ and $$(13,-27)$$ and also __________ values such as $$({1 \over 2},{1 \over 5})$$ and $$(1.3,-2.7)$$

This rectangle is parallel to the $$x$$ and $$y$$ axes. What is the missing fourth coordinate? 

$$2, 27, 327, -7, -107$$ and $$0$$ are all examples of __________.

Match the equivalent fractions and decimals.

Find the midpoint for each pair of numbers.

The signs are the wrong way round on both coordinates. It should read $$(3,-4)$$

It's below the $$x$$-axis so both need to be negative. $$(-3,-4)$$

Nothing. That is the coordinate $$(-3,4)$$

What's wrong with the labelling of this coordinate? 

The sides of this rectangle are parallel to the $$x$$ and $$y$$ axes. What is the missing fourth coordinate? 

This lesson will soon be taken down.
