# Max Maths, Year 3, Work Book, Review of subtraction facts and mental subtraction

In the Max Maths Year 3 Workbook, there is an engaging section dedicated to reinforcing subtraction skills. Practice 1 invites students to review subtraction facts and enhance their mental subtraction abilities. The exercise begins with a straightforward task where children are asked to count backwards from a larger number to find the difference. For example, to solve 13 minus 3, they would count down from 13 to reach the answer. Similar exercises follow, where pupils are required to subtract numbers like 6 from 15, 9 from 18, and 4 from 16, using a visual number line to aid their calculations.

Another activity shifts the focus to counting forwards from a smaller number to complete the subtraction. This method is particularly useful when the numbers being subtracted are close to each other. For instance, to find the result of 15 minus 9, students would start at 9 and count up to 15. Further examples are provided for practice, including 16 minus 13, 17 minus 11, and 18 minus 12. Additionally, the workbook features an exercise where students cross out cubes to visually represent and solve subtraction problems, such as 10 minus 7 and 18 minus 11. The final task on the page presents a series of subtraction problems, like 35 minus 10 and 56 minus 30, where students complete the equations by adding and subtracting strategically to find the answers.
