Max Maths, Year 2, Learn together, Addition within 100 without regrouping (2)

In the Max Maths Year 2 curriculum, students continue to build their addition skills within 100, focusing on problems that don't require regrouping. A typical problem might involve adding two numbers like 14 and 23. The method taught is to break down the numbers into tens and ones to simplify the addition process. For example, 14 is seen as 10 plus 4 ones, and 23 is 20 plus 3 ones. Students first add the ones together, which in this case are 4 ones and 3 ones, making a total of 7 ones. Then they add the tens, which are 10 and 20, to get 30. Finally, they combine the sum of the tens with the sum of the ones to get the total sum of 37. This method helps students understand the value of each digit in a number and makes addition without regrouping clearer.

A practical application of this method could involve a real-life scenario, such as Jade purchasing items for her computer. If Jade buys a mouse and a webcam, and students need to find out the total cost, they would add the prices of the two items together. To assist them, a number line can be used as a visual aid. Starting with the price of the mouse, students can jump along the number line to add the price of the webcam. First, they would add the ones to get an intermediate sum, then add the tens to find the total amount spent. This step-by-step approach reinforces the concept of place value and ensures that students are comfortable with adding larger numbers without getting overwhelmed by the process.
