Max Maths, Year 3, Work Book Rounding numbers to tens or hundreds

The Max Maths workbook for Year 3 provides a practical exercise on rounding numbers and making sensible estimates in Practice 5. The activity begins with a visual task where students are asked to estimate the number of ants depicted in an image. This exercise encourages children to develop their estimation skills by providing a guess of the total count as a range before verifying their estimate by counting the ants one by one. After counting, students record the actual number of ants and compare it to their initial estimate to evaluate its accuracy.

The workbook continues with a similar activity involving various shapes. Students are instructed to make an initial estimate of the number of shapes they see, fostering their ability to judge quantities at a glance. Following the estimation, the task requires a precise count of the shapes to determine the exact number. Students then record this number and reflect on how close their estimate was to the actual count. Additionally, they are prompted to describe the method they used for estimating, which helps them to articulate their thought process and potentially improve their estimation techniques in the future.
