Add Numbers up to 20
Addition practice with numbers to 20
Add Numbers up to 20 is a free online addition game designed for children ages 5 to 7 and ages 7 to 9. Players solve addition problems using numbers up to 20, receiving instant feedback after each answer. The game presents ten questions in a multiple-choice format, making it accessible for children who are still building confidence with addition. Each correct answer earns points toward a star rating, motivating children to replay and improve. Progress is tracked locally so children can see their improvement over time without needing an account.
Select a difficulty level to begin. The game presents a addition problem on screen with four possible answers. Tap or click the answer you think is correct. A green highlight means you got it right, and an orange highlight shows the question was tricky. After ten questions, you will see your score and a star rating. Try to earn three stars by getting nine or ten answers correct. You can play again as many times as you like to improve your score.
Addition is one of the first mathematical operations children learn, and fluency with addition facts underpins almost every other area of maths. When children practise addition regularly, they develop automatic recall of number bonds, which frees up working memory for more complex problem-solving later. This game gives young children and children in early primary school a low-pressure environment to build that fluency through repetition and immediate feedback.
This game is designed for children in Kindergarten and Grade 1 (ages 5-7), Grades 2-3 (ages 7-9). The questions are calibrated to match the skills typically taught at this level, making it suitable for classroom use, homework support, or independent practice at home. Parents and teachers can use this game as a structured learning activity that rewards effort and tracks progress.
