Frequently Asked Questions
Where can I do the passport activities with my child?
Anywhere! In the car, out and about, at the supermarket or at home. Most
activities can be done through talking with your child.
How often?
Daily for best results.
How long should we do it?
Around 10 minutes will do. Don’t overdo it, as your child may ‘switch off’.
My child is not being moved on at school. Why not?
Children will be tested on each target at regular intervals – approximately
every fortnight.
Why don’t you test straight after a practice?
We need to know that the children will remember each target forever!
My child says he was tested and passed, but is still working on this
target. Why?
We will test until they have passed the target 3 times. These tests will be
at least a fortnight apart from one another. Then the target will be ‘signed
off’ at school.
How many targets should I work on at once?
This is your choice. You can work on one target or several from the same
passport.
Can I help in school?
Yes! We are always on the lookout for help even if you can’t give up much
time. Please contact your class teacher if you’re interested.
What would I be expected to do in school?
You would be asked to work with one or two children for 15 minutes on
their numeracy passport activities e.g. once a week after lunch.
Why isn’t my child writing much down during the activities?
Children need to learn these targets mentally. Writing them down may slow
their progress. They will remember them better if this has been done
through talk and playing games.
What does the test look like?

The teacher would put some numbers in the middle column (see above). For
example, this one could be used to test the 2x table. Your child would then
start at the top and fill in as many answers in the empty column on one side
(left hander to the left side and right handers to the right side – so they
can see the middle numbers!)
Your child will be timed. If they complete the sheet correctly in 30
seconds or less they will receive the first signing of their passport. They
will then get tested approximately 2 weeks later. Once the target has
been signed 3 times, it will be ‘signed off’.
How does my child move to the next passport?
Once all their targets have been signed off, they will do a mixed test of all
their passport targets.
Why? This will ensure that they have REALLY learnt them by heart!
Double any number with up
to 1 decimal place.
Double means adding a number to itself,
e.g. 9.8 + 9.8, or multiplying the number
by 2 e.g. 9.8 x 2.
I can do this for all numbers with one
digit after the decimal point up to 9.9

1.3 = 2.6
2.4 = 4.8
3.0 = 6.0
4.1 = 8.2
1.7 = 3.4
2.8 = 5.6
3.5 = 7.0

You can double by splitting units and the
tenths number.

This needs to be done in your child’s head!
Ideas to try at home.
Your child starts with a small number (e.g. 0.1) and keep
doubling it in their head (0.1, 0.2, 0.4, 0.8 …) How far
can your child go without a mistake?
Now try 0.3, 0.6, 1.2…
Try taking it in turns with your child:
Mum says ‘0.3’ Child says ‘0.6’
Mum says ‘1.2’ Child says ‘2.4’ …
Customs Check
Write down 10 numbers with one decimal place
(Between 0 and 10). Give your child 30 seconds to
double them all.
Encourage your child to write out all the doubles from
0 to 10. Write next to each one whether it was easy,
tricky or very tricky.
Double
1.0 = 2.0 easy
1.1 = 2.2 easy
1.2 = 2.4 easy
1.3 = 2.6 easy
1.4 = 2.8 easy
1.5 = 3.0 easy
1.6 = 3.2 tricky…
Talk about any patterns you notice.
Memorise or learn all the easy doubles first before moving
onto the tricky doubles.
Halve any number with up to
1 decimal place.
I can do this for all numbers with
one digit after the decimal point up
to 9.9

Ideas to try at home:
Ruler Maths
Visualise the numbers using a centimetre/millimetre ruler.
Example: half of 2.7
Child puts their finger nail on 2cm 7mm. Now they estimate
which number is halfway along the ruler from 0cm. Then
see if you were right using the halving method on the last
page.
Beat the calculator
Parent has a calculator. Child picks a number to
halve. Who can work it out first?
Tip: Parents might want to give the child an
advantage by going slow.
Customs Check
Write down 10 numbers e.g. 8.7, 7.8 etc.
Give your child 30 seconds to halve them all.
Your child writes out all the halves of numbers from 5.0
to 9.9. Write next to each one whether they think it was
easy, tricky or very tricky.
Halve:
5.0 = 2.5 easy
5.1 = 2.55 very tricky
5.2 = 2.6 tricky
5.3 = 2.65 very tricky
5.4 = 2.7 tricky
5.5 = 2.75 very tricky
5.6 = 2.8 tricky…
Talk about any patterns you notice.
Memorise or learn all the easy halves first before moving onto
the tricky halves.
Activities to practise both doubling and halving at
the same time.
Follow Me
1.Cut out the Follow Me cards at the back of this book
and share them amongst as many players as you have
(the more the better).
2.Choose someone to start by reading out one of their
questions.
3.The person who has the answer shouts it out and
reads the question that is with it.
4.Play on until the game goes back to the person who
started.
(This could also be played like a game of dominoes.)
Car Journey Maths
Try questions like this in the car or on the bus…
“I think of a number and halve it, the answer is 2.3
Which number did I start with?”
Recall quickly multiplication facts up
to 10x10 and use them to multiply
pairs of multiples of 10 and 100
I know all my tables and can
answer questions like 30 x
70 and 40 x 200 straight
away.
10 x 70 = 700
700 x 700 = 490,000
600 x 60 = 36,000
40 x 70 = 2,800
5 x 800 = 4,000
90 x 90 = 8,100
20 x 200 = 4,000
8 x 600 = 4,800
90 x 70 = 6,300
100 x 100 = 10,000

Quick fire questions
Ask the table questions in any order:
20 x 40 = ?
50 x 700 = ?

Know all the factors of all
timetable answers up to 12 x 12
Give me any number up to 100
and I can tell you all the
numbers that ‘go into’ that
number exactly.
Example:
24?
1, 2, 3, 4,
6, 8, 12 and
24
Ideas to try at home:
Children can explore:
o Which numbers have the most factors?
o Which numbers have an odd number of factors?
o Which numbers have only 2 factors; 1 and
themselves?
