Max Maths, Year 5, Work Book, Adding and subtracting near multiples of 10 and 100

In the 'Max Maths, Year 5, Work Book', students are given the opportunity to enhance their mathematical proficiency with exercises focused on adding and subtracting near multiples of 10 and 100. One of the practice activities involves using number lines to visually represent addition and subtraction problems. For example, students are asked to draw arrows on the number lines to show calculations such as adding 9 to 35 or subtracting 19 from 65. These exercises help to reinforce the concept of estimating and adjusting by multiples of 10 and 100, which is a key skill in mental arithmetic.

The workbook also includes exercises that challenge students to identify the correct method for calculating sums and differences. For instance, they must determine whether to add or subtract a rounded number and then adjust by a small amount to find the actual answer. Additionally, the workbook provides problems where students need to complete equations by finding the missing numbers, further testing their understanding of the concepts. These activities not only improve the students' numerical fluency but also develop their problem-solving skills and their ability to work with number lines and mental strategies.
