Max Maths, Year 2, Try it, Addition pairs to 100

In the 'Max Maths, Year 2' activity, students are engaging with addition pairs that sum up to 10 and 100. They are first asked to complete a table by finding pairs of numbers that, when added together, result in either 10 or 100. Tya's column focuses on pairs that add up to 10, such as 0 + 10 and 1 + 9, while Toby's column focuses on pairs that add up to 100, with examples like 0 + 100 and 10 + 90. This exercise helps students understand the concept of addition pairs and strengthens their mental arithmetic skills.

The second part of the activity requires students to write down the addition and subtraction facts that are related to the given addition facts. For instance, if the addition fact is 10 + 90 = 100, the related subtraction facts would be 100 - 10 = 90 and 100 - 90 = 10. This helps students to see the relationship between addition and subtraction and to understand that they are inverse operations. The activity includes several examples to work through, such as 40 + 60 = 100 and 80 + 20 = 100, and also provides practice with subtraction facts such as 100 − 30 = 70. The completion of this exercise will deepen students' understanding of the number relationships within 100 and enhance their ability to quickly recall these important number facts.
