Doubling and Halving for Kids
Doubling and halving are fast mental math shortcuts that build the foundation for multiplication and division facts.
Doubling — add a number to itself
Doubling 7 means 7+7=14, the same as 7×2. Kids who master doubling facts quickly gain an entire set of times-2 multiplication facts for free.
💡 Practice: double numbers 1-10 daily until instant — this single skill unlocks fast mental math elsewhere.
Halving — split into two equal groups
Halving 14 means splitting into two equal groups of 7 each — the reverse of doubling, and the base of division by 2.
FAQ
Why teach doubling before the full times table?
Doubling facts come naturally from addition already known, making them the easiest entry point into multiplication.
