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

In Max Maths for Year 2, students are encouraged to learn addition within 100 without the need for regrouping by breaking down numbers into tens and ones. This method simplifies the addition process and aids in understanding the value of each digit in a number. For instance, when adding 23 and 45, the first step is to separate the numbers into tens and ones: 23 becomes 20 (two tens) and 3 (three ones), while 45 becomes 40 (four tens) and 5 (five ones). This breakdown is written as 23 + 45 = 20 + 3 + 40 + 5.

Once the numbers are broken down, students can easily add the ones and tens separately. In our example, adding the ones—3 and 5—gives us 8 ones. Then, adding the tens—20 (two tens) and 40 (four tens)—results in 60 (six tens). Combining these sums gives us the final answer: 23 + 45 = 20 + 40 + 3 + 5 = 60 + 8 = 68. In a practical application, Jade spends £68 on items for her computer. Another example involves Padma, who starts with 7 candies and receives an additional 12 from her mother. Breaking down the number 12 into 10 and 2, and then adding the ones (2 + 7), results in 9 ones. Combining this with the ten gives us 19, so Padma now has 19 candies in total. For further practice, students are directed to complete exercises on workbook pages 37 to 39.
