Max Maths, Year 4, Work Book, Word problems

In the Max Maths Year 4 Workbook, Practice 6 focuses on solving word problems using addition. The first problem presents a scenario where a student needs to calculate the combined cost of a classical guitar priced at $638 and an electric guitar priced at $457. To solve this, a model drawing is suggested to visually represent the problem, with the prices of each guitar added together to find the total cost. The solution to this problem is straightforward addition, leading to the total amount spent on both guitars.

The second problem involves understanding the concept of comparative height. It describes Han, who is 128 cm tall, and his brother, who is 15 cm taller than Han. A model drawing is again recommended to help visualize the difference in height. By adding the additional 15 cm to Han's height, students can determine the height of Han's brother. The workbook continues with a set of problems related to the mass of different fruits, where students must use addition to find the combined mass of various fruit pairings, such as a lime and a mango, or a tomato and a banana. Additionally, students are tasked with identifying the fruit that is 121 g lighter than the mango, requiring them to apply subtraction to solve the problem.
