L4 Measure Mass (g, kg)

This engaging Year 3 maths lesson focuses on measuring mass in grams (g) and kilograms (kg) through practical, hands-on learning rather than worksheets. Pupils explore the concept of mass by handling, estimating and weighing real objects using balance scales and kitchen scales, helping them develop a secure understanding of standard units of measurement. Children learn when to use grams or kilograms and build confidence in reading scales accurately. Through practical investigations, they compare the mass of classroom objects, sort items by weight and solve real-life problems involving mass. Pupils are encouraged to discuss their reasoning, make estimations before measuring and explain their findings using appropriate mathematical vocabulary. The lesson promotes active learning and collaboration, allowing children to deepen their understanding of mass through experience rather than written exercises. By engaging with tangible objects, pupils strengthen their ability to estimate, measure and compare mass in meaningful contexts. Designed to reduce reliance on worksheets, this lesson supports mastery of the Year 3 maths curriculum while encouraging curiosity, reasoning and real-world application of measuring mass in grams and kilograms.
