This file contains two sets of 12 task cards on finding multiples, identifying common multiples, and finding the least common multiple of two and three numbers.
**The first set (rainbow background) is more challenging. Students will need to find multiples of 12, 18, 20, etc. to answer the questions.
**The second set (red, white, blue background) uses smaller numbers. Students can find all the multiples needed to answer these questions on a 12 by 12 multiplication grid (not included).
A recording sheet is included and answer keys for both sets of cards are provided.
