Addition
Tap a level to start - you can always try again!
Warm-up - you have got this!
Ready for a challenge!
Super hard - go for it!
Build confidence with addition through interactive practice. Questions are generated dynamically so children always get fresh problems. Three difficulty levels scale from simple single-digit sums to larger multi-digit calculations, helping learners progress at their own pace.
Choose a difficulty level, then solve each addition problem by selecting the correct answer from four choices. Score points for every correct answer and earn stars at the end.
Start with Easy to warm up, then move to Medium once you can answer every question correctly. Breaking larger numbers into tens and ones makes adding easier.
Shop totals, scores in sport, and measuring ingredients all use addition. Fast number bonds free your brain for harder school problems.
Addition is the foundation of all arithmetic. Children who develop fast, reliable addition skills have a much easier time with subtraction, multiplication, and later algebra. Automatic recall of addition facts — knowing that 7+8=15 without needing to count — frees up working memory for more complex problems.
Addition games are suitable for children from Kindergarten (ages 5-6) through to Grade 5 (ages 9-11). Start on Easy mode for numbers up to 10. Progress to Medium (up to 20) and Hard (up to 100) as confidence grows. Most children in Grades 1-2 will find the Medium difficulty appropriate.
Children often struggle with crossing the ten (for example, 7+5 is harder than 6+3 because the answer crosses into a new tens group). Teach the 'bridge through 10' strategy: 7+5 = 7+3+2 = 10+2 = 12. Another common difficulty is addition of larger numbers where children lose track of place value — using base-ten blocks or a written column method can help make the tens and ones visible.
