Section 4: Working with weight
Key Focus Question: How can practical work be used to teach the measurement of weight using inexpensive resources?
Keywords: Standard units; grams; kilograms; practical work; balances; extension; differentiation; groups; demonstration.
Learning Outcomes
By the end of this section, you will have:
- helped pupils develop their understanding of weight by using progressive practical activities;
- explored ways to establish pupils’ understanding of the need and use of standard units for weight;
- explained different ways to organise your class.
Introduction
When exploring weight with pupils it is important to use a lot of practical hands on activities in the early stages so that they are able to build up mental models which will help their understanding in later stages. In this section you will plan ways to introduce your pupils to the concept of weight by following three stages:
- comparing weights of two or more objects by holding them at the same time
- estimating and measuring weight of objects using non-standard units such as stones
- measuring and comparing the weight of objects using standard units
Central to this work is the use of simple balances and using standard units that can be made from cheap and readily available materials, to enable practical group work and active learning.
