Tips for Parents & Teachers
Start with objects your child can touch and move — combining two groups of blocks or toy cars makes addition tangible.
Teach the "count on" strategy: start from the bigger number and count up. It is faster than counting everything from 1.
Practice "making 10" — it is the most powerful addition strategy and will serve your child for years.
Use addition in daily life: "You have 3 strawberries and I am giving you 4 more. How many will you have?"
