### Transcript

• 1. Learning Multiplication Level 1 Beginner
• 2. Part One Learning the Process
• 3. The Step By Step Procedure <ul><li>When Learning Multiplication, one might think of it as confusing. </li></ul><ul><li>It is a good idea to really think about the steps as you multiply. </li></ul><ul><li>Don’t forget that there are always rules you must follow when multiplying! </li></ul>
• 4. How Do I Know When I’m Doing it Right? <ul><li>You can always know by the out come! </li></ul><ul><li>If your answer is smaller than any of the numbers you multiplied by; you know you did something wrong. </li></ul><ul><li>If the answer you got is bigger than the number you multiplied by you probably got the equation right! But then you may not have. </li></ul><ul><li>It’s a good idea to check your answer with division. </li></ul>
• 5. So, Then What is the Procedure? <ul><li>The procedure is how you choose to accomplish the task. </li></ul><ul><li>If you’re working with a problem such as 2x3 you would want to get it right. </li></ul><ul><li>So you could break the problem down into sections. </li></ul><ul><li>Don’t get it? Try a practice problem and see what you get! </li></ul>
• 6. Practice Time! Directions: Count all the objects in each shape. Then when you’re done write the multiplication equation it resembles. Be sure to write it vise versa too. Also when you’re done click the button below to see the answer. Answer: ____________&___________ * * * * * * * * * * Click button to reveal answers
• 7. Practice Time! Directions: Count all the objects in each shape. Then when you’re done write the multiplication equation it resembles. Be sure to write it vise versa too. Also when you’re done click the button below to see the answer. Answer: _______2x5_____&_____5x2______ * * * * * * * * * *
• 8. Answer: ___2x5___ &___ 5x2 ________ * * * * * * * * * * At first the answer might not make sense. But there are 2 shapes and in each shape there are 5 objects. So… the answer would’ve been 2x5 & 5x2. Now, you’re probably thinking “How can it be 5x2 if there's two shapes and not 5?” Well the answer is actually quite simple. You see in addition it doesn’t matter which number comes first. That’s the same with multiplication. No matter what order you put it in it’s always going to be the same answer! So I bet you’re wondering what the answer is to 2x5 or 5x2? Well it’s ten. It’s ten because 5+5=10. And there’s 2 sets of 5. So now do you get it? If not click the more help button for extra practice. If you do get it click continue. Continue More Help 1 2 3 4 5 1 2 3 4 5
• 9. Part Two Learning the Math Facts
• 10. Face the “Facts” <ul><li>Learning your math facts is very helpful in multiplication. </li></ul><ul><li>If you know your math facts 1-12 multiplication will be a snap! </li></ul>
• 11. Practice Time <ul><li>Solve the problems below. </li></ul><ul><li>2x5=__ 2x9=__ 2x6=__ 2x3=__ 2x2=__ 2x4=__ 2x7=__ 2x1=__ 2x8=__ 2x10=__ 2x11=__ 2x12=__ </li></ul><ul><li>Click the button below to reveal the answers. </li></ul>
• 12. Practice Time <ul><li>Solve the problems below. </li></ul><ul><li>2x5= 10 2x9= 18 2x6= 12 2x3= 6 2x2=_ 4_ 2x4=_ 8_ 2x7=_ 14 _ </li></ul><ul><li>2x1= 2 2x8=_ 16 _ 2x10=_ 20_ 2x11=_ 22_ 2x12=_ 24 _ </li></ul>
• 13. Oh, those Facts! <ul><li>Did you get most of the 2 facts right? </li></ul><ul><li>I sure hope you did! Well there are so many other facts you can learn as well. Most people start of with there 2’s. </li></ul><ul><li>How about you try 3’s and 4’s and then will wrap up this lesson! </li></ul><ul><li>Sound good? Yeah, I thought so too! </li></ul>
• 14. 3’s and 4’s <ul><li>3x1=__ 3x2=__ 3x3=__ 3x4=__ 3x5=__ 3x6=__ 3x7=__ 3x8=__ 3x9=__ 3x10=__ 3x11=__ 3x12=__ </li></ul><ul><li>4x1=__ 4x2=__ 4x3=__ 4x4=__ 4x5=__ 4x6=__ 4x7=__ 4x8=__ 4x9=__ 4x10=__ 4x11=__ 4x12=__ </li></ul>
• 15. 3’s and 4’s (answers) <ul><li>3x1 =_3_ 3x2 =_6_ 3x3 =_9_ 3x4 =_12_ 3x5 =_15_ 3x6 =_18_ 3x7 =_21_ 3x8 =_24_ 3x9 =_27_ 3x10 =_30_ 3x11 =_33_ 3x12 =_36_ </li></ul><ul><li>4x1 =_4_ 4x2 =_8_ 4x3 =_12_ 4x4 =_16_ 4x5 =_20_ 4x6 =_24_ 4x7 =_28_ 4x8 =_32_ 4x9 =_36_ 4x10 =_40_ 4x11 =_44_ 4x12 =_48_ </li></ul>
• 16. Multiplication Tricks <ul><li>Anything times zero is zero. </li></ul><ul><li>When you multiply by one the number stays the same. Example: 7 x1=7 </li></ul><ul><li>When you multiply by two the answer is always an even number! </li></ul><ul><li>When you multiply by 5 the answer either ends in a 5 or 0. </li></ul><ul><li>When you multiply by ten the answer always ends in a zero . </li></ul><ul><li>When you multiply by 11 the number turns into its double-digit form. Example: 6 x11=66 </li></ul><ul><li>When you multiply by 9 you can use your fingers. For example lay your fingers out straight. Suppose you want to know the answer to 5x9. On you left hand you would count until you reach your 5 th finger, which would be your left thumb. Then put you thumb down so that you can’t see it any more. Ok now the four fingers that you can see on your left hand are the tens column. So now you have 40. Then the fingers on your right hand are the ones place. You have 5. Put them together your answer is 45! </li></ul>
