Max Maths, Year 3, Learn together, Addition up to 4 digits without regrouping (1)

In the Max Maths Year 3 curriculum, students are encouraged to learn addition up to four digits without the need for regrouping. This foundational skill is critical for their mathematical development. To illustrate the concept, the lesson presents a relatable scenario where two children, Samir and Padma, have coloured pencils. Samir has 25 coloured pencils, while Padma has 14. The task for the students is to calculate the total number of coloured pencils they have when combined.

To solve this, the lesson suggests using counting blocks as a visual aid, helping students to understand the addition process in a clear and tangible way. The sum is broken down into steps, starting with the separation of tens and ones: 25 is represented as 20 + 5, and 14 as 10 + 4. These are then added together in stages, first combining the tens (20 + 10 = 30) and then the ones (5 + 4 = 9). The final step is to add these two results together, which gives the total of 30 + 9 = 39. Through this method, the lesson demonstrates that Samir and Padma have 39 coloured pencils altogether, providing a straightforward example of adding two numbers without regrouping.
