Talk it through
Use counters, a drawing or a number line before moving to a mental method. Ask your child to explain a choice, then change one number and try the method again.
Ask: “How could you show the same answer another way?” Give your child time to explain. Return to an example after playing and ask whether they would approach it differently.
Rounding to 10, 100 and 1,000
Rounding means replacing a number with a nearby 'friendly' number that is easier to work with. Year 4 pupils learn to round any number to the nearest 10, 100 or 1,000. For example, 4,567 rounded to the nearest 100 is 4,600.
Try an example: Round 845 to the nearest 10.
The ones digit is 5, so round up to the next ten.

What to look out for
Using the wrong deciding digit. Underline the place you are rounding to and circle the digit immediately to its right.
Roman numerals to 100
Year 4 pupils learn to read Roman numerals to 100 (I to C). They also learn that, over time, the number system changed to include zero and place value, which the Romans did not have. Roman numerals still appear on clock faces, monarchs' names, film credits and buildings.
Try an example: XXVII
XX = 20, VII = 7.

27
What to look out for
Reading IX as 11. Remember: when the smaller symbol comes first, subtract. XI is 11; IX is 9.
Practise away from the screen
