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.
