Max Maths, Year 1, Learn together, Adding by bridging to 10
Maths Resource Description
In the Max Maths Year 1 curriculum, pupils are learning an essential addition strategy known as 'bridging to 10'. This technique helps children to simplify addition by breaking numbers down into tens and ones, making it easier to add them together. For instance, when Jade draws 13 lines and Samir adds 2 more, the children are encouraged to regroup these lines. They start by forming a group of 10 from the 13 lines, leaving 3 lines remaining. Adding the 2 lines from Samir to the leftover 3 lines, they reach another ten. This process can be visualised as 10 + 3 + 2, which is rearranged to 10 + (3 + 2), leading to 10 + 5, and finally totalling 15. The conclusion is that there are 15 lines altogether, demonstrating the effectiveness of regrouping to make addition more manageable.
The lesson continues with more exercises to reinforce the concept of regrouping into tens and ones. Children look at two groups of numbers and apply the same strategy. For example, when adding 4 and 13, they break down 13 into 10 and 3, and then add the 4 to the 3 to make another 10, resulting in 10 + (3 + 4) which equals 10 + 7, and thus the sum is 17. Similarly, when adding 12 and 4, they break down 12 into 10 and 2, then add the 4 to the 2 to make 10 + (2 + 4), which simplifies to 10 + 6, giving a total of 16. These exercises help pupils to visualise and understand the process of addition by bridging to 10, a foundational skill in their mathematical development.
