- think multiplication…
1 ) Partitioning the Dividend
- 420 (70 x 6) 18 (3 x 6)
- 248 ÷ 4 = (240 + 8) ÷ 4 = 60 + 2 = 62
- 8280 ÷ 9 = (8100 + 180) ÷ 9 = 900 +20 = 920
- 344 ÷ 8 = (320 + 24) ÷ 8 = 40 + 3 = 43
2 ) Compensation
- $1393 shared between 7 people
- $1400 would be $200 each but 1400 is 7 more than
1393. 7 more for 7 people = $199 each
3 ) Balancing For a Constant Quotient
- changing a division question to an equivalent question so your
answer is the same but the process is easier
- 125 ÷ 5 = (multiply both by 2) 250 ÷ 10 = 25
- 120 ÷ 2.5 = (multiply both by 4) 480 ÷ 10 = 48
- 23.5 ÷ .5 = (multiply both by 2) 47 ÷ 1 = 47
** uses the right language (NO “goes into”)
- 8 goes into 344 (NO)
- 344 goes into groups of 8
- 420 ÷ 6 =
- 420 goes into 6 groups with 70 in each group

Overall, I am very impressed with my first day with David; I feel like I have a better understanding of student challenges and feel prepared to incorporate these strategies to help students be more successful. As alluded to, here is a sneak look at some of the singing we enjoyed...
