Feed the Monster
divisibility · sorting numbers divisible by 2, 3, or 5
Use divisibility rules to decide which monster should receive each number card.
Feed the Monster is a Grade 4 divisibility activity that has students sort number cards according to divisibility by 2, 3, or 5. Groups create monsters with two, three, and five arms, then decide which monster should receive each number. The visual sorting makes divisibility rules concrete, and follow-up numbers can reveal that one value may belong to more than one divisibility group.
Use it for small-group practice after students have learned basic divisibility tests. Ask students to defend where a card belongs and whether another monster could also eat the same number.
