Recognising Equal Groups — Interactive Lesson (KS1)

Can two groups be equal even if they look different? This 15-slide interactive lesson teaches recognising equal groups by challenging what ‘equal’ really means.

Mastering Recognising Equal Groups in KS1 Maths

Children use pictures and concrete objects to help recognise equal groups, recognise and explain how they know when groups are or are not equal, and understand that groups can look different but still be equal in number. They decide whether groups of orange juice bottles, cans or red dice are equal, complete Jade’s drawing of equal groups of 4, and sort 15 pebbles into equal groups of 5 or 3. A reasoning question challenges the idea that groups which look different cannot be equal.
