Little Learning Pond › Math practice › Add & Subtract

➕ Addition and Subtraction Practice

Quick, confident adding and taking away frees a child's attention for harder math later.

These topics begin with adding to 10 and grow to adding and subtracting within 20, within 100 and within 1,000.

Topics, by the age they were designed for

The age on each topic is the age it was designed for, based on typical US school math. Schools in other countries teach topics in a different order, so treat the age as a guide and start where your child is comfortable.

Helping at home

Practice the pairs that make 10 and 20. They are the building blocks of mental math.
Let your child explain how they got an answer. Counting on, making tens and taking away are all fine ways in.
Use real life: change at a shop, scores in a game, steps on a walk.

How the practice works

Each practice round has 10 questions. Your child can type the answer or tap a choice, gets a second try, and sees the correct answer and a short hint when needed. Questions are generated fresh each time. It is free, with no sign-up and no ads, and progress and stars are saved on your device only.

Build your own course

On the Math Practice page, tap "Add to my course" on any topic from any age. Your picks are collected in one place, and a mixed round draws questions from only those topics.
