Times Tables
Year 5 Name: _____________________ Form: ___________ Practise your tables at home either with someone asking you questions or on www.mymaths.co.uk or www.sumdog.com If you are good at your tables you could try trickier questions such as 30 x 900 x and ÷ by 10, 100 and 1000

Try to complete this table:
Fraction

½
0.5
0.25
¾
To multiply by 10, move the digits one place to the left.
To multiply by 100, move the digits two places to the left.
To divide by 10, move the digits one place to the right.
To divide by 100, move the digits two places to the right.
Practise this by completing these questions (Put the number in
the correct columns, then use the rules to move the digits and
calculate the answer)
1) 89 x 10 =
6) 11.4 ÷ 100 =
2) 15 x 1000 =
7) 2.6 x 100 =
3) 1700 ÷ 10 =
8) 7 ÷ 100 =
4) 3500 ÷ 100 =
9) 1.35 x
= 1350
5) 1.9 x 1000 =
10) 32.5 ÷
= 0.325

Conversion of Metric Measures
Mass
1000g = 1kg
1000kg = 1T (tonne)
Capacity
1000ml = 1l
10ml = 1cl (centilitre)
100cl = 1l
Kite
Length
10mm = 1cm
100cm = 1m
1000m = 1km
Try these questions:
Practise the names
and properties of
these shapes on
www.mymaths.co.uk
1. Play ‘I spy’ with the shapes or ‘Guess the Shape’.
Try using the shape names and some of their
properties.
2. Play ‘Spot the Difference’ with the shapes.

Square Numbers
Factors and Multiples
A factor is a number which can be divided equally into
another number.
1) Write the factors of 24:
12 = 1
22 = 4
32 = 9
42 = 16
2) Write the factors of 18:
Can you find the rest of the square numbers up to 100?
3) Do you know the prime factors for 18 and 24?
A multiple is a number which is in the table of another.
E.g. multiples of 4 are in the 4x table: 4, 8, 12, 16...
1) Write the 1st 5 multiples of 12:
2) Write the 1st 5 multiples of 5:
3) Do you know the lowest common multiple of 5 and
12?
Prime Numbers
Prime numbers are numbers with exactly 2 factors.
For example, the factors of 17 are 1 and 17.
SO... 17 is a prime number.
Fill in the table with the factors of each number. If
they have exactly 2 factors tick the column saying
‘Exactly 2 factors’.
Co-ordinates
To read a coordinate,
you go ‘along the
corridor and up the
stairs’.
Read the x co-ordinate
first and then the
y co-ordinate.
So (3,4) is the point along 3 and then up 4.
Use the grid below to practise your coordinates
whilst writing messages to your family!
E.g. (5,1) (1,2)
(-1,-3) (-5, 4)
(5,-5)
MATHS
Now list the prime numbers from between 1 and 20?

Angles
A right angle is 900
Properties of Shapes
The angles in a triangle add up to 1800
The angles on a straight line add up to 180
0
Parallel
Perpendicular
Diagonal
Side
Corner
Edge
Face
Vertex
Regular
Irregular
The angles around a point add up to 3600
Acute – Less than 900
Obtuse – Greater then 900
Fold a piece of paper to make a right angle. Use this to
check for right angles in your home.
Identify on pictures or in furniture where you see
acute and obtuse angles.
Use a clock face. How many degrees does the minute
hand turn between 3:00 and 3:15. How many more to
get to 4:00?
Use a protractor to measure the size of some angles.
Make some shape cards and pair them with matching
properties.
Play, ‘I think of a shape’. Try to work out from the
properties which shape you are thinking of.
