Maths Resource Description
The 'Max Maths' Year 3 workbook offers an engaging exercise on converting and manipulating masses in grams and kilograms. Practice 7 focuses on adding and subtracting different masses, a crucial skill for young learners to grasp the concept of weight measurement. For instance, one task requires students to calculate the combined mass of oranges and bananas. They are provided with the individual weights of the oranges (2 kilograms and 525 grams) and the bananas (1 kilogram and 140 grams) and must add these together to find the total mass in kilograms and grams. This exercise helps students understand how to work with mixed units of mass and reinforces their addition skills.
Another part of the practice involves comparing the mass of different items. Students are asked to determine how much heavier a watermelon is than the oranges. They must subtract the mass of the oranges from the mass of the watermelon, which is given as 4 kilograms and 657 grams. This subtraction exercise challenges students to think critically about the differences in weight. Further exercises include finding the total mass of the bananas and watermelon combined, as well as a series of additional problems that require students to perform both addition and subtraction of masses presented in kilograms and grams. These tasks are designed to strengthen their understanding of weight and conversion between different metric units, as well as to enhance their arithmetic skills.
