MULTIPLICATION 3x8: ?

What does it mean? Multiplication means that you have a certain number of groups of the same size. How can you express the same quantity using numbers?

Now, identify its parts: 3 X 2 : 6 Factors : Product (Multiplier and multiplicand) : Product How do you read it? 3 X 2 : 6 Three times two equals six

Practice a)Complete b)Identify the parts of the multiplication c)Write each operation.  4X3: _____.  5x6: ______.  7x1: ______.  9x3: ______.  8x5: ______.

How did you solve the previous multiplications? -Did you use images? -Did you use time tables? -Did you addition? -Did you use your fingers to count ?

There are different ways to solve a multiplication 1.Repeated Addition: The basic idea of multiplication is repeated addition. For example: 5 × 3 = 15 or = 15

What is it? It is when you add the same number again and again in order to find the answer to a multiplication. Example: Here we have five groups, and each group has two elephants. 5 × 2 = 10 how many groups? how many in each group? We can solve it by adding: 5×2 = = 10 Fivetimes two elephants is ten elephants. Remember that you need to use the same numbers of the operation.

Now, solve the following exercises using repeated addition. a.9x8: b.6x7: c.12x4: d.6x4: e.7x9:

Now, solve the guide.
