Climbers trail · ages 10–12
Free math games for 12-year-olds
Twelve is a transition year: students firm up fractions, decimals and percentages while meeting negative numbers, ratios and their first algebra. Gaps from primary school show up quickly here, so revisiting them is worth it.
Number Quest lets them do both: Climbers for consolidation, and Scholars (ages 13 to 15) for integers, ratios and solving for x. Practice mode lets them pick one topic and work on it untimed.
