  2. Remember: With each multiplication strategy, we are asking yourselves: What Are We Really Doing When We Multiply?

  3. Quick Review of Strategy #1 - Using Arrays (Box) 32 x 6 6 x 30 = ? 6 x 2= ? 30 2 180 12 6 180 + 12 = 192. So 32 x 6 = 192.

  4. Quick Review of Strategy #1 - Using Arrays (Box) 525 x 4 4 x 500 = ? 4 x 5= ? 4 x 20 = ? 500 5 20 2000 80 20 4 2,000 + 80 + 20 = 2,100. So 525 x 4 = 2,100.
