Slide 1

Lets practice some more! This time use the strategy of using words in place of the multiplication sign (X). 2 X 2 = ?

2 + 2

Mission : Checkpoint!Checkpoint! If you have completed all 5 parts of your mission your ready to land, if not go back for review.Be able to recognize the symbol for multiplication (X).Be able to use addition to help you solve a multiplication problem.Be able to use words (groups of) to help you understand and solve a multiplication problem.Be able draw a picture to help you solve a multiplication problem. Be able to arrive at the correct answer using one of the multiplication strategies.

Lets Review!Ready to land!

Head Home!

Multiplication Matters!You know to add when you see this sign. +

2. You know to subtract when you see this sign.

3. You are going to learn to multiply when you see this sign. x

Head Home!

Mission : ChecklistYou should: Be able to recognize the symbol for multiplication (X).Be able to use addition to help you solve a multiplication problem.Be able to use words (groups of) to help you understand and solve a multiplication problem.Be able to draw a picture to help you solve a multiplication problem. Be able to arrive at the correct answer using one of the multiplication strategies.

Why does multiplication matter?Multiplication is a faster way of adding. Since you already know how to add, this will help make understanding multiplication easier. When you get stuck with a new multiplication problem, you will be able to use addition as a strategy to help you figure out the answer.However, your goal will be to eventually master your multiplication facts. This will make solving real world problems easier and faster.

Remember this symbol/sign means we are going to multiply.X

Mission : Checkpoint! 1. What should you do when you see this math symbol (X)?

addb) subtractc) multiply

Remember our goal is to understand what multiplication is and practice the strategies. Try a little more practice.Add is not the correct answer because the sign for addition is + .

This symbol/sign (X) also is another way of saying groups of .

Remember when you see the multiplication symbol/sign you can insert the words groups of to help you understand and solve the multiplication problem.

Here is an example:X 2 = 3 groups of 2

Lets see if using the words groups of in place of the X symbol helps us find and understand the answer. 3 X 2 = 3 groups of 2

If we have three groups of two, we can add the groups and find that the answer is six (6). 3 X 2 = 3 groups of 2

2+ 2+ 2

In the previous example, you saw how inserting words groups of for the sign , using addition, and/or drawing a picture helped you solve the multiplication problem.

Remember: When you get stuck, you might want to try one of these strategies. Replace the X sign with groups of to make sense of the problem.Use addition to help you solve the problem.Draw a picture to visualize the problem.

Mission: Checkpoint 22. What words could you use in place of the multiplication (X) sign to help you understand and solve the problem? 3 X 3 =

multiplicationtons of groups of

Remember our goal is to understand what multiplication is and practice the strategies. Time for a tune up. Sorry, multiplication is not the right answer. Please go back for review. Lets Review

Lets try another one! This time use addition to come up with the answer. 6 X 3 = ?6 groups of 3

How did you do? 6 X 3 = 18 3 + 3 + 3 + 3 + 3 + 3

Mission: Checkpoint 3! 3. Use the addition strategy to help you solve this problem. 3 X 6 = ?

3 + 66 + 6 6 + 6 + 6

Lets visualize the problem by drawing a picture this time. 2 x 5 = 10 2 groups of 5

5 + 5 Mission: Checkpoint 4! Use the strategy of drawing a picture to help you solve this problem: 2 X 4 = ?

a)

b)

c)

Which strategy did you use? You can also try two strategies and check your own work! 3 X 5 = 153 groups of 5= 155 + 5 + 5 = 15

Mission: Checkpoint 5!5. Using any of your strategies, what is the answer to this problem: 5 X 3 = ?

15 820

Use a different strategy this time and see if you can come up with the right answer. But, first lets look at a few more examples. Hint: Use one of your strategies: addition, draw a picture or use the words groups of to help you understand the problem.

More Examples

Pay attention. Here is another example. 1 x 2 = 21 group of 2

Back to checkpoint!

Lets try one more! Then, if your ready you can take the quiz. If your not, you can go back and review!2 X 4 = ?

How did you do? If you got this right, you might be ready to take the quiz! 2 X 4 = 82 groups of 4 = 8 4 + 4 = 8Lets ReviewTake the Quiz!

What words could you use in place of the multiplication (X) sign to help you understand and solve the problem. 2 X 2 = ?

2 ______ ___ 2 ?groups ofHow did you do? 2 X 2 = 4

2 groups of 2 = 4

If you thought of groups of and your answer was 4, good job! If not, go back and review.

Here is an opportunity to take a break. If you dont need one continue otherwise, stand up and try this yoga pose. tree pose

Remember our goal is to understand what multiplication is and practice the strategies. Try a little more practice.Add is not the correct answer because the sign for addition is + not X .Try Again!

Quiz question 2What is the correct addition problem that represents 4 X 2 = 8 ?

2 + 2 + 2 + 2 = 2 + 2 + 2 =4 + 2 =

Way to go high flier! Learning to fly this plane took time and paid off. Your practice seems to be paying off.

Way to go! Plants dont grown overnight you have to work at taking care of them. Practice your multiplication strategies and your math skills will grow! Correct answer! 6 X 3 = 18.
