Max Maths, Year 3, Practice, Adding 2-digit numbers mentally

In the Max Maths Year 3 practice section on adding 2-digit numbers mentally, students are encouraged to break down the process into more manageable steps. The 'Let's Try It' activity introduces a method that involves regrouping numbers into tens and ones before adding them together. This helps children understand the value of each digit and makes mental addition easier. For instance, when adding 12 and 53, students would break these numbers down into tens and ones: 10 and 2 for 12, and 50 and 3 for 53. They would then add the tens together, and the ones together, before combining both sums to find the total.

The 'Let’s Practise' section provides a series of 2-digit addition problems for students to solve mentally, reinforcing the concept of mental arithmetic. This part of the exercise challenges students to add numbers like 43 and 24, or 61 and 85, without the need for regrouping, encouraging speed and efficiency in mental calculations. The aim is to build confidence and fluency in adding 2-digit numbers, a fundamental skill in mathematics. Students are also directed to workbook pages 42 to 45 for additional practice, ensuring they have ample opportunity to master the skill of mental addition.
