Max Maths, Year 3, Practice, Adding and subtracting multiples of 10 and 100

In the Max Maths workbook for Year 3, students are encouraged to practice their mental arithmetic skills with a series of exercises that involve adding and subtracting multiples of 10 and 100. The first activity, "Let's Practise," consists of simple calculations designed to be completed without the aid of a calculator or paper. For example, students are asked to add 40 to 530, find 100 more than 742, and determine what is 50 less than 686, among other similar tasks. These exercises are tailored to help students quickly and accurately perform basic arithmetic operations in their heads, thereby strengthening their mental maths abilities.

The second activity presents a set of equations where students must choose the correct solution from two options. They are tasked with circling the right answers for problems such as adding 20 to 34, subtracting 200 from 781, and adding 60 to 222. The exercise includes a mix of addition and subtraction problems to ensure a comprehensive review of the concepts. The workbook provides clear instructions and a structured approach to help students confidently navigate through the problems, reinforcing their understanding of place value and the properties of addition and subtraction. After completing the exercises, students are directed to continue their practice on workbook page 40.
