Max Maths, Year 4, Work Book, Addition and subtraction with 3-digit numbers using number lines

In the Max Maths Year 4 Workbook, young learners are provided with a practical exercise to enhance their proficiency in addition and subtraction involving 3-digit numbers, with the assistance of number lines. This methodical approach allows students to visualise the calculations, making it easier to comprehend and solve the problems. The workbook presents a series of calculations that require the students to use the number lines to determine the correct answers.

The exercise, categorised as Practice 3, includes a variety of addition problems such as adding 19 to 275, 48 to 119, a larger sum of 402 to 462, and combining 375 with 299. These tasks are designed to build confidence in incrementally adding both small and large numbers. In addition to the addition problems, subtraction is also tackled, with questions like subtracting 19 from 965, removing 499 from 668, and reducing 811 by 302. By engaging with these calculations, students not only practice their arithmetic skills but also learn to effectively use number lines as a tool for visualising and checking their work.
