Today's Learning Goal:
  • Practice identifying whether a sequence is arithmetic or geometric.
  • Practice writing recursive and explicit equations for arithmetic and geometric sequences.
  • Practice creating tables and graphs for arithmetic and geometric sequences.
  • Understand efficient strategies for interpreting sequences and selecting useful representations.
Today's Materials:
  1. Laptop
  2. Pencil
  3. Guided Note Sheet
  4. Binder

Gallery Walk - Stations

In each of the given problems, I share some of the information that I know about a sequence. Your job is to add all the things that you know about the sequence from the information that I have given. Depending on the sequence, some of the things you may be able to figure out for the sequence are:

• a table;
• a graph or describe what the graph would look like;
• an explicit equation;
• a recursive equation;
• the constant ratio or constant difference between consecutive terms;
• the type of sequence;
• a story context.
Directions: With your group add one representation or piece of infomation from the list.

Volume: Please keep voices low enough where only your group can hear you. "Quiet Partner Voice"

Transitions: With your group you will rotate between each station, each stop is 4 mins, you will have 1 minute to transition.

Dog Care - Performance Task Practice

STUDENT INSTRUCTIONS

Alec’s neighbor is going on vacation for a week and has asked Alec to take care of her dog while they are gone. Alec thinks it’s a good chance to make a little money, so he agrees. The neighbor says, "Just tell me how much you want to charge." Alec tells the neighbor that he would like to think about it and then let her know.

Alec comes up with two plans:
  1. Plan A that Alec considers is to charge a dime ($0.10) on the 1st day, with the amount tripling each day for 7 days, so $0.30 on the 2nd day and so on.
  2. Plan B is to charge $10 on the 1st day and $3 more each day for each of the 7 days.
