Max Maths, Year 3, Learn together, Review of measuring mass in grams and kilograms (1)

In Year 3, students revisit the important concept of measuring mass, focusing on the units grams and kilograms. Through interactive learning, they understand how to use weighing scales to determine the weight of different objects. For example, an apple's mass can be measured in grams (g), with the scales indicating that it weighs 150 g. Students are encouraged to make estimates before measuring, allowing them to compare their guesses with the actual mass. This hands-on approach not only reinforces their understanding of the metric system but also enhances their estimation skills.

Further exploration of mass measurement introduces scales that display both kilograms (kg) and grams. This dual-readout scale is used to measure heavier objects, such as a pineapple, which in this case weighs 4 kg and 500 g. The lesson includes a practical exercise where students are asked to estimate the mass of the pineapple before checking it against the scale's reading. This activity not only solidifies their grasp of the two units of mass but also teaches them the practical application of these measurements in everyday situations. Through these exercises, students become more proficient in assessing and understanding the mass of objects in both grams and kilograms.
