Speedy Subtraction is a fast-paced subtraction test app with three levels. In just minutes of practice daily, your child will master each level and their mental maths skills will soar.
Fast and accurate manipulation of simple numbers is an essential building-block of maths confidence.
The BEGINNER level speed-tests recall of number bonds to 10 (e.g. 30 - 6, 70 - 3, 20 – 8) … master this level and your child will power through the sums faster than you ever thought possible.
Next, the INTERMEDIATE level breaks 10s and offers any 2-digit number minus a single digit (e.g. 41 – 3, 20 – 5, 53 - 9).
Finally, the ADVANCED level offers random 2-digit minus 2-digit numbers. In this level, appearing on the scoreboard is a challenge in itself.
Your child needs to spend only moments playing this game and mental maths skills will soar.
