Max Maths, Year 4, Work Book, Mass

In the Max Maths workbook designed for Year 4 students, Practice 6 focuses on understanding and writing measurements of mass for various foods. The exercise begins by presenting the students with a series of food items, each with a scale indicating their mass in grams (g) or kilograms (kg). The students are tasked with reading these scales accurately and then writing down the mass of each food item. The scales are illustrated with increments that help the students determine the mass, which ranges from lighter items measured in grams to heavier ones that may require the use of kilograms. This activity is designed to enhance the students' ability to interpret and record measurements of mass in different units, reinforcing their numerical and measurement skills.

The second part of the practice involves looking at pictures of different objects and choosing a mass that would be appropriate for each one. The options provided are in various units, including grams, kilograms, and both combined. The students must tick the mass they believe matches the object's likely weight. For example, they might choose from 90 g, 900 g, or 1 kg for a certain item. This activity encourages students to apply their understanding of mass and to use reasoning to estimate and select the most suitable mass for each object. It's a practical exercise that helps students grasp the concept of mass and its real-world applications, fostering their ability to estimate and compare different masses.
