Number Sense
A child's intuitive grasp of how numbers work — their size, relationships, what happens when you combine or split them — built well before formal arithmetic begins.
What number sense includes
- Counting forwards and backwards with confidence.
- Knowing that 7 is greater than 5 without counting again.
- Composing and decomposing numbers (8 is 5+3, 4+4, 6+2).
- Estimating — is 38 closer to 30 or 40?
- Recognising patterns and relationships between numbers.
Why it matters
Children who develop strong number sense before Class 2 sail through later arithmetic, fractions, decimals and even algebra. Children who skip this foundation and jump straight to drill-style arithmetic often struggle with word problems — they can compute, but they cannot reason about quantity.
Building it at home
Play board games with dice, count steps on a staircase, share dosa pieces equally, ask 'How many more?', compare two glasses of juice. Everyday family life offers more number-sense practice than any worksheet ever will.
