• ### Transcript

• 1. Multiplication Wrestling
• 2. What is 78 X 36?
• 3. What is 78 X 36? How do we solve this?
• 4. What is 78 X 36? How do we solve this? Think....FOIL
• 5. What is FOIL?
• 6. What is FOIL? F- First Two
• 7. What is FOIL? F- First Two O- Outter Two
• 8. What is FOIL? F- First Two O- Outter Two I- Inner Two
• 9. What is FOIL? F- First Two O- Outter Two I- Inner Two L- Last Two
• 10. Step 1: Turn your multiplication fact into a partial sum fact.
• 11. 78 X 36= (70 + 8) X (30 +6)
• 12. Step 2: Find the FOIL
• 13. Step 2: Find the FOIL (70 + 8) x (30 + 6) F-First Two (70 x 30)
• 14. Step 2: Find the FOIL
• 15. Step 2: Find the FOIL (70 +8) x (30 + 6)
• 16. Step 2: Find the FOIL (70 +8) x (30 + 6) O- Outter Two
• 17. Step 2: Find the FOIL (70 +8) x (30 + 6) O- Outter Two (70 x 6)
• 18. Step 2: Find the FOIL
• 19. Step 2: Find the FOIL (70 + 8) x (30 +6)
• 20. Step 2: Find the FOIL (70 + 8) x (30 +6) I- Inner Two
• 21. Step 2: Find the FOIL (70 + 8) x (30 +6) I- Inner Two (8 x 30)
• 22. Step 2: Find the FOIL
• 23. Step 2: Find the FOIL (70 + 8) x (30 + 6)
• 24. Step 2: Find the FOIL (70 + 8) x (30 + 6) L- Last Two
• 25. Step 2: Find the FOIL (70 + 8) x (30 + 6) L- Last Two (8 x 6)
• 26. Step 3: Add up the FOIL
• 27. Step 3: Add up the FOIL F- (70 x 30) = 2100
• 28. Step 3: Add up the FOIL F- (70 x 30) = 2100 O- (70 x 6)= 420
• 29. Step 3: Add up the FOIL F- (70 x 30) = 2100 O- (70 x 6)= 420 I- (8 x 30)= 240
• 30. Step 3: Add up the FOIL F- (70 x 30) = 2100 O- (70 x 6)= 420 I- (8 x 30)= 240 L- (8 x 6)= 48
• 31. Step 3: Add up the FOIL F- (70 x 30) = 2100 O- (70 x 6)= 420 I- (8 x 30)= 240 L- (8 x 6)= 48 2100+ 420 + 240 + 48= 2,808
• 32. SO... 78 x 36 = 2,808
• 33. 27 x 45
• 34. 27 x 45 (20 + 7) x (40 + 5)
• 35. 27 x 45 (20 + 7) x (40 + 5) F- (20 x 40)
• 36. 27 x 45 (20 + 7) x (40 + 5) F- (20 x 40) O- (20 x 5)
• 37. 27 x 45 (20 + 7) x (40 + 5) F- (20 x 40) O- (20 x 5) I- (7 x 40)
• 38. 27 x 45 (20 + 7) x (40 + 5) F- (20 x 40) O- (20 x 5) I- (7 x 40) L- (7 x 5)
• 39. 27 x 45 (20 + 7) x (40 + 5) F- (20 x 40) O- (20 x 5) I- (7 x 40) L- (7 x 5) 800 + 100+280+35= 1215
• 40. 93 x 76
• 41. 93 x 76 (90 + 3) x (70 + 6)
• 42. 93 x 76 (90 + 3) x (70 + 6) F- (90 x 70)
• 43. 93 x 76 (90 + 3) x (70 + 6) F- (90 x 70) O- (90 x 6)
• 44. 93 x 76 (90 + 3) x (70 + 6) F- (90 x 70) O- (90 x 6) I- (3 x 70)
• 45. 93 x 76 (90 + 3) x (70 + 6) F- (90 x 70) O- (90 x 6) I- (3 x 70) L- (3 x 6)
• 46. 93 x 76 (90 + 3) x (70 + 6) F- (90 x 70) O- (90 x 6) I- (3 x 70) L- (3 x 6) 6300+540+210+18= 7068
