Parental Guidance
In this unit, pupils will be adding and subtracting using mental methods and using the written column method. This week, pupils have been applying the methods used in weeks 1 and 2 to word problems.
This week’s game involves adding and subtracting 4-digit numbers– remember to always encourage your child to look at the numbers first, to consider if they can be easily calculated mentally, or if a written method will be needed.
Suggested methods can be found in the Parental Guidance pages for Unit 2 weeks 1 and 2.

You will need:
A die, some paper.
Instructions:
Together, roll a die 8 times– write down the 8 digits.
Arrange the digits to make two 4-digit numbers.
Add or subtract the two 4-digit numbers.
How close can you get to 3000?
Who was the closest?
Can you play it again with another target number?
For example:
Anna and her dad took it turns to roll the die, a total of eight times. They rolled a 4, 2, 6, 1, 1, 5, 3, and another 2.
