Max Maths, Year 4, Work Book, Totals to 100 and totals to 1000

In the 'Max Maths Year 4 Workbook', students are encouraged to engage with number pairs that total 100 and 1000. The first practice section focuses on finding the missing number in pairs that add up to 100. For instance, students are presented with a series of addition problems where one addend is provided, and they must calculate the other to reach the sum of 100. Examples include finding the number that, when added to 31, equals 100, or determining what should be added to 89 to make the total 100. This exercise helps solidify their understanding of complementary numbers and the concept of making a whole.

The second part of the practice moves on to larger numbers, challenging pupils to identify number pairs that sum up to 1000. Similar to the previous task, students are given one part of the addition equation, such as 150 or 850, and must figure out the missing addend that results in a total of 1000. This not only reinforces their comprehension of addition but also introduces them to working with four-digit numbers. Through these exercises, the workbook aims to enhance the students' addition and subtraction skills by providing them with practical and straightforward numerical problems.
