Addition Practice

Tips for faster addition

Set your number ranges, choose how many questions you want, and see how quickly you can finish.

• Start small (0-10) and widen the range only after you're consistently fast.
• Group numbers to make tens: 8 + 7 = (8 + 2) + 5 = 15.
• Add left-to-right for multi-digit numbers (hundreds -> tens -> ones).
• Use compensation: add to a round number, then adjust back.
• Common mistake: forgetting to carry when crossing 9 -> 10.
• Common mistake: rushing and swapping digits (e.g., 47 + 18 -> 55 instead of 65).
• Try speed sets: 20 questions in a row, then beat your time.
• If you stall, reduce ranges for 2 minutes, then increase again.
