  4. Multiplication Factsare easiest to learn when... • You can find patterns. • You can use songs. • You can use stories. • You can relate them to what you already know.

  5. Zero’s Pattern0 times any number is 0 • 0 x 2 = 0 • 0 x 3 = 0 • 0 x 8 = 0 • 0 x 1 = 0 • 0 x 0 = 0 • 0 x 4 = 0

  6. What is 0 x 9 = 0

  7. One’s Pattern1 times any number is equal to the number • 1 x 5 = 5 • 1 x 7 = 7 • 1 x 6 = 6 • 1 x 1 = 1 • 1 x 8 = 8 • 1 x 9 = 9

  8. What is 1 x 5 = 5

  9. Two’s PatternMultiplying any number by 2 is the same as doubling the number. • 2 x 3 = 6 • 2 x 7 = 14 • 2 x 4 = 8 • 2 x 1 = 2 • 2 x 2 = 4 • 2 x 9 = 18

  10. What is 2 x 5 = 10

  11. Five’s Pattern Step 1Cut the number you are multiplying in half • 5 x 3 = 1.5 • 5 x 7 = 3.5 • 5 x 8 = 4 • 5 x 1 = .5 • 5 x 2 = 1 • 5 x 6 = 3

  12. Five’s Pattern Step 2 If you are multiplying an odd number, drop the decimal point 1 . 5 • 5 x 3 = • 5 x 7 = • 5 x 5 = • 5 x 1 = • 5 x 9 = . 3 5 2 . 5 . 5 4 . 5

  22. Nine’s Pattern Step 1Subtract 1 from number you are multiplying • 9 x 3 = 2 • 9 x 7 = 6 • 9 x 8 = 7 • 9 x 1 = 0 • 9 x 2 = 1 • 9 x 6 = 5

  23. Nine’s Pattern Step 2Add a 2nd number that totals nine with the 1st number 9 7 + • 9 x 3 = 2 • 9 x 7 = 6 • 9 x 8 = 7 • 9 x 1 = 0 • 9 x 2 = 1 • 9 x 6 = 5 = • 9 x 3 = 27 • 9 x 7 = 63 • 9 x 8 = 72 • 9 x 1 = 9 • 9 x 2 = 18 • 9 x 6 = 54 9 3 + = 9 2 + = 9 9 + = 9 8 + = 4 9 + =

  35. Real Life Applications Congratulations!!!

  36. You have been selected to build a Garden!

  37. The town council of Stone Mountain decides to beautify the town. They build square flower beds of different sizes and surround them with square tiles. Take a look.

  38. 1 by 1 bed 2 by 2 bed 3 by 3 bed

  39. What is the area of the 1 by 1 bed excluding the tiles? 1 x 1 = 1 What is the area of the 1 by 1 bed including the tiles? 3 x 3 = 9

  40. Similarly, work out: ….the area of the 2 by 2 bed excluding the tiles. 2 x 2 = 4 …the area of the 2 by 2 bed including the tiles. 4 x 4 = 16

  41. Now, the 3 by 3 flower bed…. … area excluding the tiles… ? 3 x 3 = 9 … area including the tiles… ? 5 x 5 = 25

  42. Represent your answers by using a bar graph.

  43. Represent your answers by using a pie chart.

  44. Flower bed ? x ? ? x ? 1 x 1 3 x 3 2 x 2 4 x 4 3 x 3 5 x 5 Flower bed with tiles Let's summarize Interesting Pattern!
