We are nearly finished with Chapter 2 in math. We have been working on estimating (to add, subtract, multiply by 3 digits and do long division), find factors, and multiples. Our test on chapter 2 will be on Monday, November 4.
Finding common multiples will help you later in the year when we learn fractions. Common means the same in this context. To find common multiples, list the first 12 multiples of both numbers. Then, cross out any that they do NOT have in common. Circle the multiples that appear in both lists. Finally, list those numbers they have in common.
You can find the least common multiple this way too. It's the smallest multiple they have in common, so in the above example you can see that the least common multiple of 6 and 8 is 24.
Can you find the least common multiple of 3 and 4? Answer in the comments below.
