L2 Measure Lengths (Non-Standard)

Help your Year 1 pupils build a foundational understanding of length and measurement with this engaging Working Without Worksheets lesson on measuring length using non-standard units . Children explore how to measure everyday classroom objects using cubes, paperclips, or rubbers, developing key mathematical vocabulary such as longer , shorter , and equal to . Through guided modelling and interactive discussions, pupils learn how to measure accurately by starting and finishing at the correct points and lining up non-standard units without gaps or overlaps. The animated teaching slides model both accurate and inaccurate measuring techniques , encouraging reasoning and problem-solving as children identify what makes a fair and reliable measurement. Hands-on activities make learning memorable and interactive, promoting teamwork and talk-rich mathematical understanding. This practical, no-worksheet lesson ensures children grasp the concept of measurement before moving on to standard units like centimetres, making it ideal for mastery-based maths teaching.
