Max Maths, Year 3, Try it, Finding complements to 100

In this exercise suitable for Year 3 students, the task is to understand the concept of complements to 100. The activity is designed to help children grasp how different numbers add up to make 100. In part one, students are presented with a series of simple addition and subtraction problems. They are asked to find the missing number, or complement, that will complete the equation to equal 100. For example, they must determine what number should be added to 12 to reach 100, and similarly, what number must be subtracted from 100 to leave 37. This exercise not only reinforces their understanding of addition and subtraction but also helps them to become familiar with the concept of number complements.

The second part of the exercise applies this mathematical concept to a real-world scenario involving money. Tya has a budget of £100 to spend on various toys, and the students' task is to calculate the change she would receive from £100 after purchasing each item. Students will look at the price of each toy, such as a car for £45 or a bike for £96, and work out the difference from £100, ensuring they express the change using correct money notation. This practical application helps to develop their arithmetic skills and introduces them to basic financial literacy. The instructions also guide the students to refer to their workbook on page 41 for further practice and learning.
