Two best-friend words in maths. By the end you'll spot them everywhere — in skip counting, sharing snacks, and building number rectangles!
A multiple of 5 is any number you land on when you count in 5s: 5, 10, 15, 20… Each hop is one jump of 5.
Tap each hop in order to count in 5s 🐸
Tap all the numbers you would say when counting in 4s. Find them all to win! 🎯
Hint: start at 4, then keep adding 4 each time.
A factor of a number divides it into equal groups with nothing left over. Here are 12 cookies shared perfectly:
3 groups of 4 = 12. So 3 and 4 are both factors of 12. ✅
Tap a number to test it. If 12 splits evenly, it lights up green. If there's a leftover, it turns red — then just try another! 🌈
Factors of 12 are hiding among 1 to 12. Can you catch all six?
Factors love to hold hands! Two factors that multiply to make 12 are a factor pair. Tap each card to reveal its partner. 🤝
1×12, 2×6, 3×4 — every pair makes a neat dot-rectangle of 12.
Tricky bit: small numbers that divide 12 are factors. Bigger numbers you reach by counting in 12s are multiples. Sort each one!
Remember: small & inside = factor. Big & counted = multiple. 🌟
