Estimating Reasoning and Rounding Year 2

Before children can estimate, they need to be able to round up or down. This is a great introduction to rounding to the nearest multiple of 10 up to 100. The children can practice identifying which multiple of ten is on either side of a given number. They then use the rounding rule to round up or down. This is a great differentiated activity to show mastery maths and reasoning with numbers up to 100. Children will be required to reason with problems such as Adam can read 8 pages a day. Estimate how many he can read in a week. The children will round first to solve this answer and show their reasoning. Encourage use of APE it - Answer it, prove it and then explain it to achieve mastery skills.
Suitable for the new year 2 curriculum in maths.
