Introduction<br />

How can <strong>Inspire</strong> <strong>Maths</strong> help you <strong>and</strong><br />

your Year 6 pupils prepare for Key<br />

Stage 2 <strong>SATs</strong>?<br />

We have selected a number of questions from the 2016<br />

KS2 <strong>SATs</strong> papers <strong>and</strong> highlighted relevant pages from<br />

the <strong>Inspire</strong> <strong>Maths</strong> Pupil Textbooks which will help your<br />

Year 6 pupils to answer these questions.<br />

Pupils following the <strong>Inspire</strong> <strong>Maths</strong> programme will build<br />

<strong>and</strong> consolidate knowledge <strong>and</strong> underst<strong>and</strong>ing year<br />

on year. <strong>Inspire</strong> <strong>Maths</strong> will give them the mathematical<br />

language, deep underst<strong>and</strong>ing <strong>and</strong> confidence so they<br />

are fully prepared for <strong>SATs</strong>.<br />

1 ABC is a triangle.<br />

A<br />

B<br />

The three sides are AB, BC <strong>and</strong> CA.<br />

C<br />

Let’s recall<br />

the parts of<br />

a triangle. It has three<br />

sides <strong>and</strong> three angles.<br />

B<br />

In triangle ABC, the base BC = 6 cm <strong>and</strong> the height AD = 4 cm.<br />

D<br />

Area of triangle ABC = area of triangle ABD + area of triangle ADC<br />

Area of triangle ABD = 1 × area of rectangle FBDA<br />

2<br />

= 1 2 × 2 × 4<br />

= 4 cm 2<br />

Area of triangle ADC = 1 × area of rectangle ADCE<br />

Four of the triangles have the same area.<br />

Which triangle has a different area?<br />

the base <strong>and</strong> AD is<br />

called the height.<br />

AB is the base <strong>and</strong><br />

CF is the height.<br />

= 8 cm 2<br />

So area of triangle ABC = 4 + 8<br />

= 12 cm 2<br />

Now area of rectangle FBCE = 6 × 4<br />

= 24 cm 2<br />

Half of its area = 12 cm 2<br />

So area of triangle ABC = 1 × area of rectangle FBCE<br />

2<br />

= 1 2 × 6 × 4<br />

= 1 × base BC × height AD<br />

2<br />

The lengths 6 cm <strong>and</strong><br />

4 cm of rectangle FBCE<br />

are the base <strong>and</strong> height<br />

of triangle ABC.<br />

Triangle ABC is half<br />

of rectangle FBCE.<br />

Calculate the area of<br />

parallelograms <strong>and</strong> triangles.<br />
