Geometric and Arithmetic Sequences and Series Review - Section 2: Review Sunken Treasure Game

I think it is important to model the kind of relationships that students will see during their exam and give them instant feedback. Reflecting on this lesson I would model the relationships in various ways previous to this review. The activity in this lesson allows you to have students practicing the problem sets and getting instant feedback, but I would also allow time at the end to clarify misconceptions that were brought up during the review. During my last NCTM visit I was told to always phrase questions as "What are your questions" rather than "Are there any questions" as we know there are questions that everyone has. Please reference Edward Burger's "5 Elements of Effective Thinking". I used this approach referenced from this book and found that it resulted in many more responses and questions.

During this activity I really also focus on MP#3. I create an environment in which the students can critique the reasoning of others by creating team building activities. I also choose to group teams by certain features based on a few characteristics. Sometimes I have heterogeneous groups based on ability, sometimes homogeneous groups based on ability. I have even tried groups of all boys and girls. I have some classes with very few girls and have researched that if a girl is in a group with all boys they are much more likely to not offer feedback and critique their peers. For this activity group by homogenous groups. The stronger students can work at a faster pace and challenge each other, while I usually work with the lower level groups by providing much more scaffolding. The nice thing about this activity is that groups can still "win" even if they are slower than other groups. it is just a matter of chance once they find a solution.

# Geometric and Arithmetic Sequences and Series Review

Lesson 5 of 6

## Objective: SWBAT represent arithmetic and geometric sequences/series verbally, visually, in lists/tables, graphically, as a recursive rule/pattern, an explicit rule, and in summation notation using Cornell notes in a review activity.

## Big Idea: Represent arithmetic and geometric sequences/series with various models (MP#4) using a cooperative learning review activity (MP#3).

#### Quick Write

*10 min*

The point of this QW is to get them thinking of the what they need improvement on for this introductory unit.

Students will enter the classroom and answer the following question in their binder or on a piece of paper (teacher choice, I have a required binder with Quick Write section they are graded on)

"I am still struggling with the concept of ____________________. I plan on getting assistance during __________________."

So far in this unit I can see students struggling with creating explicit rules and writing functions. I plan on spending time reviewing this concept further depending on their Quick Write answers.

#### Review Sunken Treasure Game

*70 min*

I like to play this sunken treasure game for reviews, especially when there is a series of questions involved. Instead of just handing them a series of questions, they get to play a game involving the questions. They can work at their own pace and still win a prize, which is also important to me.

Students will be playing a game with the below attachments. They will receive the series of questions face down and told to not turn it over until stated. The Sunken Treasure Smartboard Game will be shown on the board. Students answer each question as a team, one team member brings all of the packets to the teacher/co-teacher/para to check answers. Once all of the questions have been checked and approved, the team chooses a number on the board. If even one is incorrect, I will let them know that they have not all agreed upon an answer and will have to discuss and come to a consensus (MP#3). Behind one number is a "treasure". You can choose for the treasure to be what you want, I give candy (mints, red hots, dumdums, gum) or extra credit points. There are 10 different scavenger board hunts that they can play, so when a treasure is found you can simply choose a different board. The game keeps going until time runs out. Explanation of the game can be found here.

There is flexibility in this lesson since whatever questions are not answered during the game can be assigned as homework.
