In this learning activity, fourth-grade students work on their understanding of factors and factor pairs. Specifically, they determine all possible pairs of factors for the given six numbers: 24, 18, 16, 40, 50, and 30.

To find factor pairs for the number 24, you need to find two numbers that multiply together to equal 24. Start with the number 1; since 1 times 24 equals 24, (1, 24) is a factor pair. Next, try 2 because 2 times 12 equals 24, so (2, 12) is another factor pair. Keep going like this, trying the following numbers: 3 times 8 equals 24, so (3, 8) is a pair, and 4 times 6 equals 24, so (4, 6) is a pair. Once you've checked all possible pairs, you have all the factor pairs of 24: (1, 24), (2, 12), (3, 8), and (4, 6).
