How to Teach Addition to Young Children
A step-by-step guide to teaching addition, from using fingers and manipulatives to mental math strategies like doubles, near doubles, and making 10.
Addition looks simple to adults because we've forgotten how many cognitive leaps it actually contains. You have to understand that numbers represent quantities, that quantities can be combined, that the combined quantity has a single name, and — the hardest one — that this works the same whether you count pebbles or jellybeans or pounds sterling.
The sequence that actually sticks: count to ten, then count on from any number, then add with fingers, then discover doubles (2+2, 5+5), then near doubles (5+6 = 5+5+1), then the make-ten strategy. By the end of that sequence a child doesn't need to count on their fingers anymore — not because you took the fingers away, but because the math got easier than the fingers.
The biggest mistake parents make is jumping to written sums too fast. If a five-year-old is writing 3 + 2 = 5 but can't actually put three counters and two counters together and count them, you don't have addition yet — you have copying. The section below separates the two.

Frequently Asked Questions
What age should I start teaching addition?+
Most children are ready to add small numbers (within 5) around age 4 to 5, once they can reliably count to 10 and understand one-to-one correspondence.
Should kids use fingers to add?+
Yes, in the early stages. Finger counting is a normal developmental strategy and research shows it actually supports later mental math. Children drop it naturally once they build fact fluency — usually around age 7 or 8.
What's the 'make 10' strategy?+
It's a mental math trick: to solve 8+5, break the 5 into 2+3, add the 2 to 8 to make 10, then add the remaining 3 to get 13. It's the foundation of fast mental arithmetic and should be taught in Year 1.
When should children memorise addition facts?+
Addition facts to 20 should be fluent by the end of Year 2 (age 7) in most curricula. Drill comes after understanding — not before.
