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,…………

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.

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

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.

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)
