Meet the Math Facts: Multiplication & Division

Learning About Multiplication

Today, we’re going to learn about a fun math fact: 4 times 5 equals 20! Multiplication is like adding the same number over and over again. Let’s see how it works!

Understanding 4 Times 5

When we say 4 times 5, it means we have four groups of five things. Imagine you have four baskets, and each basket has five apples. If you count all the apples, you will have 20 apples in total. That’s why 4 times 5 equals 20!

Counting by Fives

Another way to understand this is by counting by fives. Let’s count together: 5, 10, 15, 20. See? When you count by fives four times, you reach 20. That’s the magic of multiplication!

Practice Makes Perfect

Now it’s your turn to practice. Try to find things around you that you can group into fours and fives. Maybe you have toy cars or crayons. Count them and see if you can make groups of four or five. It’s a fun way to learn multiplication!

Fun Fact

Did you know that multiplication is like a shortcut for adding? Instead of adding 5 + 5 + 5 + 5, you can just say 4 times 5. It’s quicker and easier!

Keep Exploring

Keep practicing your multiplication skills, and soon you’ll be a math whiz! Remember, math is all about having fun and discovering new things. Happy learning!

  • Can you think of other things you might have in groups of four or five at home or school? How many do you have in total if you multiply them?
  • Why do you think multiplication is a useful skill to learn? Can you think of a time when you might use multiplication in your daily life?
  • Have you ever noticed patterns when you count by fives or other numbers? What patterns do you see, and how do they help you understand multiplication better?
  1. Apple Basket Challenge: Gather some small objects like buttons or coins. Pretend these are apples. Create four groups with five objects in each group. Count all the objects together to see if you have 20. Try rearranging them into different groups, like five groups of four, and see if you still get 20. Discuss with a friend or family member why the total number doesn’t change.

  2. Skip Counting Hopscotch: Draw a hopscotch grid outside or on a large piece of paper. Instead of numbers, write multiples of five: 5, 10, 15, 20, etc. Hop through the grid while saying the numbers out loud. This will help you practice counting by fives and understand multiplication better. Can you make it to 50?

  3. Multiplication Detective: Go on a hunt around your home or classroom to find items that come in groups of four or five. For example, look for chairs, books, or toys. Count how many groups you find and how many items are in each group. Write down your findings and see if you can create a multiplication sentence from what you discovered, like “3 groups of 5 equals 15.”

Here’s a sanitized version of the YouTube transcript:

[Music] Four times five equals twenty. Four times five equals twenty. Four times five equals twenty. [Music] Four times five equals twenty. [Music] Hmm. Four times five equals twenty. [Music] Four times five equals twenty. Four times five equals twenty. Four fives equals twenty. One, two, three, four, five equals twenty. Four times five equals twenty. [Music] Five, ten, fifteen, twenty equals [Music] twenty. Twenty equals four times five equals twenty. [Music] You.
