What your child learns
Class 2 to 9 · ages 7–14
Abacus Flash is flash anzan practice: numbers flash one after another, on abacus beads or as digits, and the child adds them in their head. It trains the abacus visualisation that abacus classes aim for, plus focus and working memory. Choose 1, 2 or 3 digits and a speed to match your level.
Tips to get better at Abacus Flash
Picture the beads moving as each number flashes — that is the anzan skill.
Keep a running total; do not try to remember every number.
Slow the speed down until you get 8 out of 8, then speed up one step.
A way abacus students practise mental maths: numbers are shown one at a time, very quickly, and the student adds them by picturing the abacus beads in their mind.
My child is new to the abacus. Can they play?
Yes. Start with 1 digit, slow, and the abacus view. Children who do not read the beads yet can choose digits.
Which speed should we start with?
Slow (1.5 seconds per number) until all 8 are right, then medium (1 second), then fast (0.65 seconds).
Is it free?
Yes — free in the browser, with the free TalentJR Abacus course for learning the beads.
