Scales are used
to 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 are
used to tell and measure the time.
An abacus has
sets of 10 beads on rods.
It is used for counting
and other calculations.
A calculator
can work out
calculations quickly.
Make sure that you
press the right keys
and check the
answers against
your estimate!
Maths Equipment
A thermometer
is used to
measure the
temperature.
Protractors are
used for measuring
and drawing angles.

3. Place Value
Place value tells us how much each digit is worth in a number.

If you are not sure what a number is,
write the headings above each digit to help you.
This number has
seven digits.

4. Square Numbers
When 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 are
1, 4, 9, 16, 25, 36, 49, 64, 81 and 100.
We can write four squared as 4 x 4 or 42.
© www.teachingpacks.co.uk
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 of
a 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

5. Addition
Addition is counting up or finding the total of some numbers.
Here are some more words that are linked to addition:
add more
plus increase total
sum altogether

5 + 3 = 8
We can use a number line to help us count on.
++
+ +
The addition sign

6. Fractions
Fractions show us how much of something we have.
The parts of a fraction have special names:

The denominator tells us
how many parts something
was divided into.

8. 3D Shapes
3D 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.

something is. We measure temperature using a
thermometer.
We usually measure temperature in ºC
(degrees Celsius) but it can also be measured
in ºF (degrees Fahrenheit).

11. Pie Chart
Pie charts are used to compare
information. A pie chart looks like a
pie that is split into slices.
In this survey, 16 people chose their
favourite sport. The pie is split into 16
sections and the sections are coloured
to show the results.
Look at the pie chart to compare the results.
