Max Maths, Year 6, Work Book, Review of adding and subtracting decimals

In the Max Maths Year 6 Workbook, students are provided with a comprehensive review of adding and subtracting decimal numbers. Practice 5 focuses on reinforcing these concepts through a series of exercises. The first activity uses visual aids in the form of coloured squares to help students complete the addition of decimal numbers. For example, they are given problems such as 2.4 + 4.3 and 6.06 + 5.85, where they must not only calculate the sums but also demonstrate their understanding by representing the addition with coloured squares. This visual approach assists in solidifying the concept of decimal place values and the process of addition.

The subsequent exercises involve straightforward addition and subtraction of decimal numbers without visual aids, encouraging students to apply their skills more abstractly. Problems range from simple additions like 2.5 + 3.7 to more complex calculations such as 17.8 + 29.9, and from basic subtractions like 8.4 - 3.3 to more challenging ones such as 57.2 - 23.5. This variety ensures that students have ample opportunity to practice and master the addition and subtraction of decimals with different place values. The workbook's structured approach helps students to progressively build confidence and proficiency in handling decimals—an essential skill for their mathematical development.
