# Before and After Big Numbers

### Purpose:

The purpose of this activity is to help your child to say a number 1, 10, 100, 1000 before and after a given number in the range 0 – 1 000 000.

### Link to the Number Framework:

Number Sequence, Stage 6

Calculator

### What to do:

Ask your child to enter a thousands number. For example: 725 346. Check they have entered it correctly.
Ask your child: What digit will we need to change to find the number 10 000 after 725 346?
(the 2 because it is in the ten thousands column)
Can you add 10 000 on the calculator? (press + 10 000 =)
What is the number 10 000 after 725 346 – read it from the calculator? (735 346)
Ask your child to make further changes to the number. For example:
What number is 100 before 735 346?
It is best to limit the changes to one column, otherwise it becomes quite challenging for children.

### What to expect your child to do:

To recognise the place value of numbers in the columns, e.g. the 2 is in the ten thousands column.
