Meet the Math Facts: Multiplication & Division

Learning About Multiplication

Hey there! Today, we’re going to learn about a fun math fact. Have you ever wondered what happens when you multiply four by ten? Let’s find out together!

Four Times Ten

When we say “four times ten,” it means we are adding the number ten, four times. Let’s count together:

Counting by Tens

First, we have ten. Then, we add another ten to make twenty. Next, we add another ten to get thirty. Finally, we add one more ten, and we reach forty!

So, four times ten equals forty. Isn’t that cool?

Visualizing the Math

Imagine you have four groups of ten apples. If you count all the apples, you will have forty apples in total. That’s just like saying four times ten equals forty!

Practice Makes Perfect

Now it’s your turn! Try to think of other numbers you can multiply by ten. Can you figure out what five times ten is? How about six times ten? Keep practicing, and you’ll become a multiplication master!

Fun Fact

Did you know that multiplication is like a shortcut for adding the same number over and over again? It makes math quicker and easier!

Keep Learning

Remember, math is all about having fun and discovering new things. Keep exploring and learning, and you’ll find out just how amazing numbers can be!

  • Can you think of a time when you had to count or group things in your life, like toys or snacks? How would multiplying help you count them faster?
  • Imagine you have a magic wand that can multiply things. If you could multiply any object in your room by ten, what would it be and why?
  • When you see numbers in the world around you, like on a clock or in a game, how do you think multiplication could help you understand them better?
  1. Apple Grouping Activity: Gather 40 small objects, like buttons or blocks, and pretend they are apples. Divide them into groups of ten. Ask the children to count how many groups they have and how many objects are in each group. Then, ask them to multiply the number of groups by ten to find the total number of objects. This will help them visualize multiplication as repeated addition.

  2. Multiplication Scavenger Hunt: Go on a scavenger hunt around your home or classroom to find items that come in groups of ten. For example, look for ten pencils, ten books, or ten crayons. Once you find them, ask the children to multiply the number of groups by ten to find the total number of items. This activity encourages them to see multiplication in their everyday environment.

  3. Question Time: Ask the children, “If you had to multiply a number by ten, what would you choose and why?” Encourage them to think of different numbers and predict the results. This question helps them apply multiplication to numbers they choose and understand the pattern of multiplying by ten.
