  1. *Don’t forget to sign in!* What model of division does this comic illustrate? What is the rate?

  2. Agenda • Make-up Videos: Thursday at 1pm in MATH 303 and Friday at 8:40am in MATHE 141 • Exam 2 is one week from today (multiplication 3.3 and division 3.4). • If you plan to take the exam at the DRC, please let me know so I can have an exam for you! • One more video (no class notes) • Using base 10 blocks • Algorithms – how do they work?

  3. Kevin

  4. Kevin • Does Kevin always say what he means? • Does Kevin explain mathematically why this algorithm works? What is going on here? The teacher began to make some connections… • Let’s back up and solve the comic division problem using base 10 blocks

  5. Use base 10 blocks to solve 215÷13.

  6. Use base 10 blocks to solve 215÷13.

  7. Use base 10 blocks to solve 215÷13.

  8. Use base 10 blocks to solve 215÷13. 13 x + = 215 (quotient) (remainder)

  9. Use base 10 blocks to solve 215÷13.

  10. Now look at the “scaffolding” algorithm • Last page of the division worksheet. • If you have completed this and can explain mathematically what this algorithm is doing, go on to Exploration 3.20 (p. 74). Be ready to present one of the problems to the class – explaining mathematically why we do each step.

  11. Homework • Exploration 3.20 (p. 74) due Monday • Division Worksheet due Wednesday
