Number sense is the intuitive feel for quantity. A child with good number sense knows that 8 is a lot but 3 is a little, that 5 + 2 is close to 5 + 3, and that six objects look bigger when spread out than when bunched together. It's foundational to all future maths.
What is Number Sense?
Counting with Purpose
Rote counting (1, 2, 3, 4...) is fine, but children need to count things that matter. Count the buttons on a cardigan. Count the crackers at morning tea. Count the days till the class excursion. Counting should answer real questions: "How many are there?"
Subitising Activities
Subitising is recognising quantity without counting. Show a card with 5 dots for 1 second. "How many?" Children should see 5, not count to 5.
Activities: Dice games, dominoes, finger combinations, scattered objects. "I'm showing 4 fingers. You show 4 fingers without counting."
Comparing and Ordering
"Do we have more boys or girls today?" "Who has more blocks?" "Line these piles from smallest to biggest." Comparison is how children build understanding of relative size.
Part and Whole Understanding
Three counters: 2 red, 1 blue. "We have 3 altogether. We can make 3 from 2 and 1." This is the foundation for addition and subtraction. Use any object: blocks, beads, pasta, leaves.
Number Songs and Rhymes
Five Little Monkeys, Five Currant Buns, 10 Green Bottles—these embed number relationships through rhythm and repetition. Kids remember them. Revisit them in many contexts.
Real Contexts
Number isn't abstract for Year 1s. It's about apples in a basket, children on a mat, spots on a ladybird. Use the environment: shells on the beach, insects in the garden, leaves in autumn.

Mixed Counters and Manipulatives
Coloured counters, beads, and loose parts for building number sense through play.
Avoid Pressure
Some Year 1s aren't ready to count to 10. Some are counting to 50. That's fine. Number sense develops gradually. Pressure backfires.
