Multiplication

MULTIPLICATION
Grade 2
Math Lesson 3

• ​Multiplication is repeated addition.
  You add groups of the same amount together.
  For example: you add 3 groups of 2 cherries.
  At this point, you don't even need to mention the word “multiplication.”

NOTE:
In math, multiply means the repeated addition of groups of equal sizes.

​Factor Definition

​​Product

​Product is the result we get by multiplying factors together.

What is Multiplication?

• Repeated Addition

• division+addition=subtraction-multiplication

• Repeated subtraction

• repeated addition of groups of equal sizes

Multiple Choice

How many methods are there to solve multiplication?

(From the video)

• 6

• 8

• 0

• 2

• 3

Multiple Choice

What are the Methods? method1:

(Solve depending on the examples in the video)

Example: There are 4 bowls and in each bowl, there are 5 fish.

• we subtract the fish from the bowl.

• We add the number if fish in each of the fish bowl.

• we divide the fish into more bowl and the subtract the remaining bowls.

• we subtract the number of bowls from the number of fish.

• we don't feed the fish for 4 days.

Method 2:

(Solve depending on the examples in the video)

Example: There are 4 bowls and in each bowl, there are 5 fish.

• Add the numbers

• Subtract the numbers

• Multiply the numbers

• Divide the numbers

What can we say about Methods 1 and 2?

(conclude)

• We can tell that the way to solve them is different but we always sum up with the same product.

• We can tell that they subtract each number twice.

• We can tell that they divide the product with no remainders.

• We can tell that they are repeated addition.

We use the × sign to multiply factors together and = to show the product.
