Working Without Worksheets – Reception Maths: Compare Length This Working Without Worksheets Reception maths lesson introduces children to the concept of comparing length. Through practical activities, real-life examples, and hands-on exploration, children begin to use key mathematical language such as longer, shorter, and the same length. The starter activity makes learning engaging and relatable: Ask children to look at their own hands and compare their fingers. Discuss which finger is the longest and which is the shortest. Introduce the key vocabulary in context so children can use it to describe everyday objects. In the main input, children explore comparing lengths using familiar objects: Compare two pieces of ribbon, identifying which is longer and which is shorter. Move on to pencils of different lengths, demonstrating how to line them up carefully to compare. Discuss examples where the objects are the same length, reinforcing the importance of accurate comparisons. Use questioning such as: “Which pencil is the longest? Which is the shortest? How do you know?” The independent activity encourages hands-on exploration: Children select two objects from around the classroom. They line them up carefully and decide which is longer and which is shorter. This develops early reasoning skills and gives opportunities to apply new vocabulary in practical contexts. The plenary reinforces learning: Challenge children to find something in the classroom that is longer than a crayon and shorter than a ruler. Discuss their choices as a class, focusing on accurate use of the terms longer, shorter, and the same length.
