Drill number boulders apart with a factor that divides them, digging a factor tree down through the dirt until only prime gems are left.
Factor Dig plays like Dig Dug: the child drills a number boulder with a factor that divides it, the boulder cracks into two smaller boulders in the tunnels below, and the tunnels grow into a factor tree until every branch ends in a prime gem (36 = 4 × 9 = 2 × 2 × 3 × 3) while Pookas crawl in through the dirt. A jammed drill shows the remainder (50 ÷ 3 = 16 r 2) and a pump on a composite shows its hidden factor (91 = 7 × 13), targeting the habits of stopping a tree at a composite leaf and calling every odd number prime. Best for Grades 4–6.
