Max Maths, Year 2, Try it, Doubling 2-digit numbers

In the Max Maths programme for Year 2, students are introduced to the concept of doubling 2-digit numbers through simple addition and multiplication. The lesson demonstrates that doubling a number is the same as adding the number to itself or multiplying it by two. For example, to double the number 14, children can calculate 14 plus 14, which equals 28, or simply multiply 14 by 2 to reach the same result. This concept is further illustrated with the number 13, where doubling it, either by addition or multiplication, results in 26.

The lesson continues with a practical exercise where students are asked to complete a table by doubling multiples of 5. Starting with the number 5 and doubling it to get 10, the table progresses with 10 doubled to 20, 15 to 30, and 20 to 40. Students are then tasked with continuing the pattern by doubling the subsequent multiples of 5 up to 50. This activity not only reinforces the doubling concept but also encourages observation of the patterns that emerge when numbers are doubled. Students are prompted to reflect on what they notice about the pattern of numbers as they work through the exercise. The lesson directs them to continue their practice on workbook pages 85 to 86 to further solidify their understanding of doubling 2-digit numbers.
