Deffenbaugh's Algebra 1 Classes

This page has been created to inform parents and students about the daily activities of my Algebra 1 classes. I will post notes, reminders, etc on here.

Happy Pi day!

Here is the Unit test review. We will work on it tomorrow and Wednesday and I plan on Testing Thursday (weather permitting)

02/18/15- Students have been studying Coordinate rules for transformations. Learning how to tell points to "move" on a coordinate plane. Once I told them that this is similar to the process video game designers use to make their favorite games, they were intrigued.

02/04/15- Example of translation by reflection.

02/03/15- New Unit is called Butterflies, Pinwheels, and Wallpaper. Your kids will be investigating transformations, congruence. One of my students drew this for me. I had to share.

02/30/15- This is an example of a Geometric Sequence your kids investigated in Function Junction.

02/29/15- This is an example of an Arithmetic Sequence your kids investigated in Function Junction

02/29- Your students are studying Arithmetic and Geometric Sequences at the moment. It is an enrichment of what they have already learned about linear and exponential functions. They are now using function notation and looking at data in tables as a series of terms.

Parent/ Teacher conferences February 3rd and 5th! Sign up sheets have been sent home with your children. You should be meeting with their 3rd period teacher. Have a great day!

We studied killer plants in Investigation 2 of the Growing, Growing, Growing book. I saw this one at the store and had to get it for the classroom. I thought we might try to track it's growth over this semester. What should i name it? Audrey 2?

Notes from 01/14/15- nth root and rational exponents.

01/13/15- Students used patterns from Investigation 5.1 to come up with more specific rules of exponents. Very interesting discussions today. Some kids used a "guess-and-check" strategy. Some used inference. Pictured below is what they came up with.

Students have learned how to make graphs on the calculators that represent the data given in problems. (They still have to come up with an equation on their own first).

Checking the temperature of the water every 5 minutes. Finding the difference between water temp and room temp.

07/01/2015

We have studied Exponential decay patterns in making ballots (finding the areas of the new ballots after cutting), in fighting fleas (amount of medicine left in the body after a certain time), and, after today, the cooling pattern of hot water. Students have learned how to spot the initial value and calculate the decay factor. They are able to come up with an equation just by looking at patterns in tables.

Students are picking up right where they left off. They are off to a great start this year! Here are some notes from 01/06/15.

I handed out instructions today to all who were interested. I have more if needed.

12/03/14- Vocabulary from GGG investigation 1.3

12/02/14- GGG Investigation 1.2- Students investigated a similar growth pattern in this problem. The only difference is the starting value. They had to alter their equations a bit.

12/01/14- Growing, Growing, Growing Investigation 1.1- Students investigated exponential growth by making ballots and observing the pattern of increase. They made a table and a graph, then came up with an equation.

I am going to reschedule the unit test originally planned for tomorrow. Instead, we will review further. We will be in the computer lab Monday and Tuesday and I plan on testing Wednesday.

11/11/2014

We are having our "Looking for Pythagoras" Unit Test this Friday, 11/15. We will review Thursday in class. If you want to go ahead and get started on it, here are the problems we will be working as a review:

Pg 16 #'s 15-25
Pg 29 #4
Pg 30 #'s 38 & 39
Pg 31 #'s 40 & 42
Pg 71 #'s 3-7
Pg 90 #5
Pg 92 #9 (a only)
Pg 93 #10 (a only)
