Add and subtract positives and negatives, crossing zero on the number line, then drop your buoy on the answer — integer arithmetic made visual.
On each turn, a child adds or subtracts positive and negative integers — crossing zero in either direction — then drops a marker at the answer on the number line. The visual approach builds a real feel for integer arithmetic: working with negative numbers rather than just applying a sign rule. Best for Grades 5–6, or any student who has met integers and wants to make sense of them.
A free, no-signup, no-ads math game for Grades 5–6 — practising integers, negative-numbers, addition, subtraction. Play in your browser on the KidsDoMath games hub or explore more Arithmetic games.
