Max Maths, Year 2, Try it, Estimating numbers to 100

In an engaging lesson from Max Maths for Year 2 students, children are introduced to the concept of estimating numbers up to 100. The 'Try it' section presents a simple yet effective strategy for comparing two numbers to determine which one is larger when the tens digits are identical. The lesson explains that the key to comparison lies in looking at the ones digits. For example, when comparing two numbers that both have eight tens, the number with seven ones (87) is greater than the number with two ones (82). This method is visualised with illustrations showing the ones clearly, making it easier for young learners to grasp the concept of number magnitude.

The lesson encourages students to practice this skill with exercises in their workbooks, specifically directing them to pages 10 to 17 for further learning. Through these activities, students will solidify their understanding of how to compare numbers within the 100 range by counting the ones. This foundational skill in number sense is presented in a child-friendly manner, promoting confidence and competence in young mathematicians as they navigate through the world of numbers and engage with basic arithmetic concepts.
