Max Maths, Year 2, Learn together, Subtracting tens and hundreds (2)

In the engaging Max Maths Year 2 lesson, children learn about subtracting tens in a practical and relatable way. The lesson starts with a simple story where Han shares 10 nuts with Toby, which provides a context for the subtraction problem: 53 minus 10 equals 43. This demonstrates to the children that after giving away 10 nuts, Han has 43 nuts left. The learning continues as Han generously gives another 10 nuts to Padma, leading to a new subtraction problem: 43 minus 10 equals 33, leaving Han with 33 nuts. This sequence of transactions helps reinforce the concept of subtracting tens from a given number.

The lesson further solidifies this mathematical concept by providing additional subtraction examples, such as 63 minus 10 equals 53, and subsequent tens subtracted from the result, showing a clear pattern. The children are encouraged by Han to cross out a ten to visually comprehend the subtraction process, reinforcing the mental calculation of subtracting by tens. This interactive approach is further supported by a prompt to visit workbook page 51, where children can practice this skill with more exercises. The lesson concludes with a confidence-building statement, "I can subtract by tens mentally," and a challenge to the children, asking, "Can you?" This encourages the students to reflect on their understanding and ability to perform similar calculations mentally.
