After completing the boomerang problem and a short review over Arithmetic Sequences, we started looking a patterns generated by multiplication.
For more help with Arithmetic or Geometric Sequences: See Cool Math Sequences & Series Lessons 1, 2, 5, 7 is what you are responsible for currently.
Or you may log-in to your TenMarks account and find Arithmetic at the end of the Relations/Functions unit and the Geometric at the beginning of the Exponential Functions unit.

A few practice problems from class today (9/28/11)
Students are currently reworking missed problems from last weeks assessment on Relations / Functions.
Today, after completing the boomerang problem, they were given 11 equations to solve. This will be a pre-test to determine where they stand in ability to solve a variety of equations. Students, you must remember, these are our goals for the unit!
Rate each one – 3! You’ve got it and do not need more practice.
2! You’ve almost got it, but could use a little more practice!
1! Not sure where to start and need some instruction.
History of the Boomerang
Yesterday was our first Kentucky Leadership Network meeting for Mathematics. One of our sessions was an introduction to Lessons created through the Mathematics Assessment Project. Today, I shared a problem which we were presented as part of our training.
Students had 10-15 minutes to work individually on their solutions.
Tuesday we’ll revisit our responses, then work within small groups to create a better solution.
Students will then receive 4 sample solutions to analyze and discuss.
Some sample questins shared in class today. This may help you get started on your practice test. See you unit organizer to guide your questions.
Afterschool sessions begin Tuesday, September 20. Students should meet in the library and plan for pick up at 3:45.
There will always be a math teacher on-site.
Remember you can also report to Room 148 before school Tuesday – Friday for any help/questions; make-ups.
Students were asked to create 3 tables of values – one of each: linear, quadratic, expoential (not in that order). At the beginning of class, students will exchange their tables, and determine which function family each tov belongs to. They may/may not be able to determine if any patterns exist in the radical and rational functions.
