Max Maths, Year 3, Work Book, Converting between grams and kilograms (2)

In the 'Max Maths, Year 3, Workbook', students are provided with practical exercises to enhance their understanding of mass, particularly focusing on converting, adding, and subtracting masses in grams and kilograms. One of the practice activities, Practice 7, involves adding and subtracting the masses of different fruits to find total weights and differences in weight. For example, students are asked to calculate the combined mass of oranges and bananas by adding their individual weights given in kilograms and grams. They must then express the total mass in both units correctly. The exercise also challenges students to compare the mass of a watermelon to that of the oranges, requiring them to subtract one mass from the other to determine the difference in grams.

The workbook continues with further exercises that require students to apply their skills in addition and subtraction of masses in different contexts. They are presented with pairs of weights, which they must either add together or subtract one from the other, and then write down the resulting mass in kilograms and grams. These exercises not only test the students' ability to perform basic arithmetic operations but also their understanding of the metric system and how to convert between units of mass. The workbook is designed to build confidence and proficiency in handling real-life problems involving mass, an essential skill for young learners.
