Lesson: Divison

Division is the process of splitting a number into equal parts. In this lesson, we’ll learn how to divide numbers up to 5, understand how to work with remainders, and solve word problems using division.

Basic Division Facts

Division tells us how many equal groups we can make from a larger number. It’s the opposite of multiplication.

  • Example: 10 ÷ 2 means “how many groups of 2 can we make from 10?”
    • The answer is 5 because 10 divided by 2 equals 5.

Here are some key division facts up to 5:

  • 10 ÷ 2 = 5
  • 15 ÷ 3 = 5
  • 20 ÷ 4 = 5
  • 25 ÷ 5 = 5

Division with Remainders

Sometimes, when we divide numbers, there is a number left over. This leftover is called a remainder.

  • Example: 14 ÷ 3 means “how many groups of 3 can we make from 14?”
    • You can make 4 full groups (because 3 x 4 = 12), but 2 is left over.
    • So, 14 ÷ 3 = 4 remainder 2.

Division Word Problems

Division is useful in solving real-life problems where you need to split things equally. Look for clues like “shared equally” or “divided among” in word problems to know when to use division.

  • Example: There are 15 cookies, and you want to share them equally among 5 friends. How many cookies does each friend get?
    • 15 ÷ 5 = 3, so each friend gets 3 cookies.

Division Facts

It’s important to remember basic division facts. Knowing these facts helps you divide quickly and correctly. Here are some examples:

  • 5 ÷ 1 = 5
  • 10 ÷ 2 = 5
  • 15 ÷ 3 = 5
  • 20 ÷ 4 = 5
  • 25 ÷ 5 = 5

Mixed Division Problems

Sometimes, you’ll have a mix of division problems, including ones with remainders. Practice helps you get better at recognizing when to divide and how to handle different types of division problems.

  • Example: What is 18 ÷ 4?
    • 4 goes into 18 four times (4 x 4 = 16), and there are 2 left over.
    • So, 18 ÷ 4 = 4 remainder 2.
