Max Maths, Year 3, Work Book, Finding complements to 100

In a Year 3 maths workbook, students are encouraged to explore the concept of finding complements to 100, with a focus on halving and doubling numbers. One exercise prompts students to halve the number 70. They are guided through the process by breaking down the number into smaller, more manageable parts, which makes it easier for young learners to understand the concept of division. The workbook provides a visual aid by leaving blank spaces for the students to fill in the numbers that, when added together, will equal half of 70. The answer is then revealed to be 35, and students are reminded that while 70 is an even number, 35 is an odd number.

An additional task asks students to double the number 47. The exercise begins with the addition of 7 + 7 to help students understand how to double the last digit. The workbook then breaks down the process into smaller steps, prompting students to fill in the blanks to arrive at the doubled total. By adding together the tens and the units separately, students can see that doubling 47 results in 94. The workbook reinforces the concept of odd and even numbers by highlighting that 47 is an odd number and that its double, 94, is an even number. A similar exercise is presented for halving the number 82, where students learn that half of 82 is 41, showcasing the transition from an even number to an odd number through the halving process.
