Max Maths, Year 6, Learn together, Review of addition and subtraction (2)

In the 'Max Maths' programme for Year 6, students are encouraged to reinforce their understanding of subtraction through a practical exercise. The task involves completing a subtraction table where only the unshaded cells need to be filled in. This table is structured such that each row and column header represents a number from 11 to 20, and the cells contain the result of subtracting the column number from the row number. Some cells have been pre-filled to guide the students. For example, subtracting 11 from itself results in 0, and this pattern is repeated down a diagonal line, where any number subtracted from itself gives the same result.

After completing the table, students are asked to work in small groups to analyze their findings. One group member is tasked with identifying a pattern within the completed table, while another is responsible for explaining why this pattern occurs. This activity helps students to observe that when any number is subtracted from itself, the answer is always zero, which is why the table shows a diagonal line of zeros. The exercise not only enhances their subtraction skills but also encourages collaborative learning and critical thinking. For further practice and to consolidate their understanding, students are directed to continue their work on page 34 of their workbook.
