Max Maths, Year 3, Learn together, Word problems (mass) (2)

In a Year 3 maths lesson from Max Maths, students learn to solve word problems involving mass. The example provided helps them understand how to calculate the difference in mass between two individuals, Tya and Padma. To visualise the problem, a model is drawn, showing Tya's mass as 29 kilograms and 800 grams, and Padma's as 25 kilograms and 650 grams. The solution involves a straightforward subtraction of the two masses. Students are guided to subtract both the kilogram and gram parts separately, which reveals that Tya is 4 kilograms and 150 grams heavier than Padma. This step-by-step approach aids in reinforcing the concept of mass comparison and subtraction.

After learning through the example, students are encouraged to apply their skills to a new problem: finding the total mass of Toby and Tya. They are instructed to use a model to represent the problem, which helps them organise their calculations and better understand the concept of combining masses. The lesson directs students to workbook pages 184 to 187 for further practice, where they can try similar problems and continue to develop their ability to work with mass in the context of word problems. This hands-on approach not only teaches mathematical concepts but also promotes problem-solving skills in young learners.
