Max Maths, Year 2, Learn together, Estimating numbers to 100

In the 'Max Maths' curriculum for Year 2, students are introduced to the concept of estimating numbers up to 100. This skill is particularly useful when dealing with large quantities that would be time-consuming to count individually. For example, Padma faces the task of counting jelly beans. To make the process more manageable, she decides to estimate the total number before counting each jelly bean. The suggested strategy for estimation involves grouping the jelly beans in tens, as counting in tens is a simpler and quicker method compared to counting each item one by one. This approach not only saves time but also reinforces the students' ability to count by multiples of ten, which is a fundamental skill in early mathematics education.

The lesson encourages collaborative learning, with the phrase "Let's Learn Together" prompting students to engage with the concept of estimation as a shared activity. By working together, they can discuss and refine their estimating techniques. Padma's example demonstrates a practical application of estimation, showing that by grouping items into tens, children can make a reasonable guess at the total number. This method is then put to the test as Padma and her peers count the jelly beans to verify the accuracy of their estimate, providing a hands-on experience that highlights the value and effectiveness of estimation in everyday situations.
