1. Class Opener:
Find the next two terms of each pattern. Then write a rule to describe the pattern.
1,3,5,7,9,11………
-2,-4,-6,-8,-10,-12……..
.2,1,5,25,125,625……….
50,45,40,35,30,25………..
512, 256, 128,64,32,16……
2,5,8,11,14,17………………
16,32,64,…………

2. Quick Notes:
You can describe some patterns with a sequence, or ordered list of numbers.
Each number in a sequence is a term.
A recursive formula defines the terms in a sequence by relating each term to the ones before it.
A formula that expresses the nth term in terms of n is an explicit formula.

3. Quick Write:
When, how and why are patterns useful in our everyday lives?

4. Group Activity Ground Rules:
For each Group:
Checker: ensures that all group members understand or agree, and that each member is ready to present if called upon.
Facilitators: Read the questions to the group, focus the conversation on the current task, and encourage progress towards the next question.

5. Group Activity Ground Rules:
Managers: Pick up any materials needed for the activity and keep track of time.
Recorders: take note of the groups responses, from the ongoing discussion points through final agreements. (at the same time, each group member will keep a personal record of the answers on their own copy of each station worksheet)
