Scales are usedto measure the

mass of different items.

We can use a measuring cylinder to measure

amounts of liquid.

Rulers and tape measures are used to measure length.We also use rulers to draw straight lines.

Clocks and stopwatches areused to tell and measure the time.

An abacus hassets of 10 beads on rods.

It is used for countingand other calculations.

A calculatorcan work out

calculations quickly.

Make sure that you press the right keys

and check the answers againstyour estimate!

Maths Equipment

A thermometer is used to

measure the temperature.

Protractors areused for measuring and drawing angles.

1, 6 5 9, 0 2 3If you are not sure what a number is,

write the headings above each digit to help you.This number has

seven digits.

Square NumbersWhen a number has been multiplied by itself,

we say that the answer is a square number.Can you see why they are called square?

The first ten square numbers are1, 4, 9, 16, 25, 36, 49, 64, 81 and 100.

We can write four squared as 4 x 4 or 42.

1 x 1 = 1

2 x 2 = 4

3 x 3 = 9

4 x 4 = 16

5 x 5 = 25

A square root is the opposite ofa square number.

If 4 x 4 = 16, the square root of 16 is 4. We use the square root sign (√)

to show this, so √16 = 4

AdditionAddition is counting up or finding the total of some numbers.

FractionsFractions show us how much of something we have.

The parts of a fraction have special names:

3D Shapes3D shapes have faces, vertices and edges.

Faces are the flat

surfaces.A vertex is another word for corner. The

plural is vertices.

Edges are where the two faces meet.
