Max Maths, Year 5, Work Book, Written calculations using decimals (1)

In the "Max Maths, Year 5, Work Book," students are introduced to written calculations involving decimals through a variety of engaging exercises. Practice 6 focuses on the addition and subtraction of decimal numbers. The first activity requires the use of coloured squares to visually aid in the process of adding decimal numbers together. Students are given an example to follow, which helps them to understand how to align the decimal points and add the values correctly. This visual method supports the development of their conceptual understanding of decimal addition.

The subsequent exercises involve adding and subtracting decimal numbers without the visual aid of coloured squares. Students are presented with pairs of numbers and are tasked with calculating the sum or difference. For example, they may be asked to add 1.5 and 1.7 or subtract 7.4 from 1.2, ensuring that they align the decimal points to achieve the correct answer. The exercises progress in difficulty, with later questions involving larger numbers and more complex decimal places. This structured approach allows students to build confidence and proficiency in handling decimals in written calculations.
