What we are Learning This Week

Math: Mrs. Bennett

We will continue to work through our next math unit on factors and multiples! This unit builds on what we just learned about area—students will now use arrays to represent numbers and explore all the different ways they can be formed, helping them discover each number’s factors. They’ll also learn how to find common factors and multiples, and understand the difference between prime and composite numbers. These skills create a strong foundation for future topics like fractions and divisibility rules. Students will focus on learning divisibility rules to help them determine all the factors of a given number. The rules students will learn are listed below! Unfortunately, there aren't great rules for 7 and 8.

🔢 Divisibility Rules 🔢

1: Every number is divisible by 1.

2: A number is divisible by 2 if its last digit is even (0, 2, 4, 6, or 8).

3: A number is divisible by 3 if the sum of its digits is divisible by 3.

Example: 237 → 2 + 3 + 7 = 12 → 12 ÷ 3 = 4 ✅

4: A number is divisible by 4 if the last two digits form a number divisible by 4.

Example: 316 → 16 ÷ 4 = 4 ✅

5: A number is divisible by 5 if its last digit is 0 or 5.

6: A number is divisible by 6 if it is divisible by both 2 and 3.

9: A number is divisible by 9 if the sum of its digits is divisible by 9.

Example: 333 → 3 + 3 + 3 = 9 ✅

10: A number is divisible by 10 if its last digit is 0.
