Question 1

When developing the written record for multiplication computation it is helpful to encourage students to follow these suggestions EXCEPT:
◦ Use sheets with base-ten columns.
◦ Record partial products.
◦ Record the combined product on one line.
◦ Mark the subdivisions of the factors.

Question 2

Which is an example of the compensation strategy?
◦ 63 × 5 = 63 + 63 + 63 + 63 + 63 = 315
◦ 27 × 4 = 20 × 4 + 7 × 4 = 80 + 28 = 108
◦ 46 × 3 = 46 × 2 (double) + 46 = 92 + 46 = 138
◦ 27 × 4 is about 30 (27 + 3) × 4 = 120; then subtract out the extra 3 × 4, so 120 -12 = 108
