Find the thousands digit first
In 5,614 the thousands digit is 5. For 1000 more, make it 6: 6,614. For 1000 less, make it 4: 4,614. The hundreds, tens and ones never move, so do not rewrite them — copy them.

Say it before you write it
Read 3,208 as three thousand, two hundred and eight. A thousand more is four thousand, two hundred and eight. Saying it out loud stops you changing the wrong digit, which is the most common slip in this work.

Crossing into ten thousands
1000 more than 9,340 is 10,340. Nine thousands become ten thousands, so a new column opens up. Going the other way, 1000 less than 10,120 is 9,120 and the ten-thousands column closes again.

Chains and jumps
You can jump more than once: 2,700, then 3,700, then 4,700, then 5,700 is three jumps of 1000, which is the same as adding 3000. Spotting that saves time in word problems about savings or distances.

This is the part you'd do in your book at school. Pick the pieces below, write here or on paper, and photograph anything you draw or work out.
The cost of a school trip
A school is planning a trip to a wildlife park. The coach costs £480 however many people go. Entry costs £9.50 for each pupil and each adult goes free. The school says every pupil must pay the same amount, and the trip must not lose money.
If 60 pupils go, the coach works out at £8 each, so the total for each pupil is £17.50. If only 40 pupils go, the coach works out at £12 each, so the price rises to £21.50. The teacher explains that the coach is a fixed cost and the entry is a cost per person — which is why the price per pupil changes when the number changes.
The school decides to charge £20 and to use anything left over for a second trip later in the year.
