L3 Convert Between Kilograms and Grams

Description

Build your Year 4 pupils’ confidence in converting between kilograms and grams with this engaging, worksheet-free maths lesson designed for the Spring Measurement unit.

This comprehensive resource helps children understand the relationship between kilograms (kg) and grams (g), using the key fact that 1 kilogram = 1,000 grams. Through clear teacher modelling, interactive teaching slides and practical activities, pupils learn how to convert confidently between the two units by multiplying and dividing by 1,000 before applying their understanding in reasoning and problem-solving tasks.

The lesson begins by revisiting units of mass before introducing kilogram and gram conversions using visual models, worked examples and class discussion. Pupils then reinforce their learning through practical, hands-on activities, partner work and comparison tasks that encourage mathematical reasoning and deepen conceptual understanding.

Designed as a worksheet-free lesson, this resource promotes active learning while providing teachers with assessment opportunities, key questions and guidance on addressing common misconceptions.
