New Curriculum edition
A guide for children and parents
Welcome to your new booklet explaining all about the updates to our
exciting Mathematics challenge.
There are 10 different levels for you to try and achieve. Each level will
have a number of key maths challenges to practise at home and then be
tested on in school. Every time you prove to your teacher you can
successfully do the different skills within each level, you will receive a
certificate and advance to the next level.
The levels
Circle
Semi-Circle
Triangle
Oblong
Pentagon
Hexagon
Heptagon
Octagon
Nonagon
Decagon
The shape up in maths levels are linked to the key objectives from the
new curriculum that teachers want children to be able to do mentally.
They are important skills that you should know off by heart or be able
to work out very quickly.
The aim will be to have a shape up in maths day every half-term, giving
you approximately 6 weeks to practise the skills.
Good luck and enjoy the challenge!
These are the skills that you will need to practise to help you

£ 5.97 x 3 = £ 17.91
You should call the value to the nearest pound and then adjust
your answer at the end by how much extra you added
Example
£2.99 x 3 – call the £2.99 three pounds instead
Then do £3 x by three to make £9
But you add an extra 1p three times, so you need to subtract 3p
from £9 – this make as a final total of £8.97
You will get unseen money problems to adjust
Convert any unit of measurement using multiplying and dividing by
10, 100 or 1000
Learn
10 mm = 1cm
100 cm = 1m

(just halve it and halve it again)
50% of 92 = 46
50% of 12.68 = 6.34
(just halve it)

Be able to adjust near multiples of ten to help mentally multiply two
by two digit numbers
Learn
21 x 12 = 252
19 x 13 = 247
32 x 15 = 480
You need to adjust the number to the nearest ten to make the
calculation easier
Example
21 x 12 = 252
First call 21 twenty and then multiply it by 12 to make 240
Then add one more 12 (because we only did 20 x 12 so far and we
need to do 21 x 12) so 240 + 12 = 252
You will also get unseen examples to calculate
