Max Maths, Year 6, Learn together, Addition of 2- and 3-digit numbers (1)

In the Max Maths Year 6 curriculum, students are introduced to the concept of addition with 2- and 3-digit numbers through practical examples. One of the exercises involves a scenario where two children, Han and Tya, have collections of coloured pencils. Han has 25 coloured pencils, and Tya has 14. To determine the total number of pencils they have together, students are encouraged to use counting blocks or a similar visual aid to help them understand the process of addition.

The addition is broken down into simpler steps to aid comprehension. Firstly, the numbers are separated into tens and ones: 25 is divided into 20 and 5, while 14 is divided into 10 and 4. These numbers are then recombined in a way that makes it easier to add them together: 20 + 10 becomes 30, and 5 + 4 becomes 9. By adding these two results together, students find that the total is 39. Therefore, Han and Tya have 39 coloured pencils in total. This method of breaking down and recombining numbers is a foundational skill in arithmetic that helps students understand the properties of addition and gain confidence in their mathematical abilities.
