  1. Distributive Property with Partial Products Method of Multiplication • Multiplying 2-digit by 2-digit Numbers

  2. Don't be scared! • You can do this

  3. Let's start with a problem • I know you're a little short and funny looking... • But I meant a math problem • Let's go with 56 x 78

  4. Expand your mind, man • Actually, you should put the two numbers in expanded form • 50 + 6 • 70 + 8

  5. Set it up • So we're multiplying • (50 + 6) x (70 + 8)

  6. Equality for All! • Since there are 4 numbers to deal with... • Place 4 equal signs under the problem

  7. Order Up • Okay, the commutative property does state that order doesn't matter, but... • You should follow a certain order here because it's easy to get mixed up • So let's start with the ones place on bottom

  8. Multiply the 8 by both numbers on top • Good idea to go right to left

  9. Move Over • Now let's get to the tens place on bottom • Write the 70 down by the last two equal signs

  10. Keep the pattern going • Multiply 70 times the ones place on top

  11. And Going • Now multiply the 70 times the tens place on top

  12. It All Adds Up • Now add up your partial products to find your final answer

  13. So 56 x 78 = 4,368 • Here's a picture of your mother
