number 8 - odd one out - subitising (subitizing) problem solving

This is a great resource that children enjoy. They have to problem solve to find the odd one out. I laminated the sheets, cut out the crosses and stuck velcro on the squares and cross. This enables the children to work independently by placing the cross on the ‘odd one out’ before explaining to me what they found.

I also placed the number sentences with Numicon representations on the back of these sheets for a reference to the children.

Why is this activity important?

When children subitise it means they can work out how many in a collection without having to count everything they see. They can describe how many by looking and thinking which helps your child build their mathematical imaginations. Spatial structures are critical mathematical representations that children need to be able to make meaning from. It later enables children to work flexibly with numbers and operations.
