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

The Max Maths workbook for Year 3 provides a practical approach to enhancing students' skills in adding and subtracting multiples of 10 and 100. Practice 3 in the workbook offers a series of exercises that encourage pupils to apply their understanding of place value and basic arithmetic operations. The first activity involves using number lines to visually support the process of adding or subtracting multiples of 10 or 100 from given numbers. For example, students are tasked with calculating the result of 895 minus 70 and 647 plus 200, with number lines provided as a guide to help them jump in tens or hundreds accordingly.

The second set of exercises requires students to fill in missing numbers to complete addition or subtraction problems. This not only tests their computation skills but also their ability to understand the inverse relationship between addition and subtraction. For instance, they need to determine what number added to 38 equals 88, or what number subtracted from 388 leaves 308. The third and final part of Practice 3 presents a challenge where students must find a certain number more or less than another number. This includes finding 30 more than 360 or 300 less than 847, encouraging learners to mentally calculate the difference and sum when dealing with multiples of 10 and 100. These exercises are designed to build confidence and fluency in basic arithmetic, a fundamental skill for young mathematicians.
