Dock rush! Numbers roll toward the shipping dock — SPLIT the composites into factor pairs, SHIP the primes whole. Watch out for sneaky 51s and 91s.
Players choose number tiles and snap them onto the belt until their product reaches the target value — working through factor pairs, identifying which numbers are prime, and building common multiples. Each round deepens understanding of factors, multiples, and prime factorisation as connected ideas rather than separate rules. A solid match for Grades 4–6, or any child beginning to see how multiplication links to the structure of numbers.
