Max Maths, Year 2, Practice, Addition within 100 with regrouping

In the Max Maths Year 2 practice for addition within 100, students are introduced to the concept of adding two 2-digit numbers with regrouping. This is a key mathematical skill that helps children understand how to handle sums that exceed ten in either the ones or tens place. The method involves breaking down each number into its tens and ones components before proceeding with the addition. For example, when adding 37 and 27, students are encouraged to separate these numbers into tens (30 and 20) and ones (7 and 7), then add each set separately before combining them for the final sum.

The 'Let's Practise' section provides exercises that reinforce this concept of regrouping. Students are given pairs of 2-digit numbers to add together, such as 19 + 18, 52 + 29, and 46 + 37. They are prompted to break down each number into tens and ones, add the tens together, add the ones together, and then combine these sums while keeping in mind the need to regroup if the ones add up to more than ten. This methodical approach helps to build a strong foundation in addition by ensuring that students are comfortable with the concept of carrying over numbers from the ones to the tens column. To further practice and solidify these skills, students are directed to workbook pages 42 to 46 for additional exercises and examples.
