### A Year in Review, Blogs for NROC’s Algebra 1—An Open Course

My goodness! Almost a year has gone by since I made my first post about teaching with NROC’s Algebra 1—An Open Course.  I hope you’ve found the ideas interesting and the material useful.  Feel free to let me know what sort of posts you’d like to see more of, and I’ll do my best to provide them.

Now, it’s time to review! This blog post bundles the past year of posts. Which is to say, here you’ll find links (one in each title) leading to my 11 previous blogs. Quick descriptions are provided. Enjoy!

Writing Real Life Algebra Equations
After viewing the creation of a real-life equation, students create and illustrate their own algebra equation.
(This blog uses the presentation from NROC's Algebra 1--An Open Course, Unit 2 Topic 1: Solving Equations. The presentation is now available on Hippocampus.org.)

Constructing the Idea of Absolute Value
Using the NROC absolute value game, “Absolutely,” students construct the meaning of the absolute value symbol. They create a set of class notes and hypothesize about how to solve for X in absolute value equations.
(This blog uses “Absolutely,” a game from NROC's Algebra 1--An Open Course, Unit 2, Lesson 2, Topic 1: Absolute Value. The puzzle is also now available on Hippocampus.org under "Simulations".)

Algebra Equations to Budget a School Party
Students make and solve algebra equations while budgeting for an imaginary school event. Students can follow up with budgeting for a real event or fundraiser.
(This blog uses a summative project and problems from NROC's Algebra 1--An Open Course, Unit 2 Team Project: Students Rule. They are currently only available if you have direct access to the course.)

Tutor Sim: Feedback While Reviewing Functions
With a simulated tutor providing hints and feedback as needed, the student(s) answer interactive multiple choice questions that deal with functions and their graphs. The blog suggests how to introduce and use the sim as part of a topic review.
(This blog uses the simulation from NROC's Algebra 1--An Open Course, Unit 3 - Tutor Sim: Snowboarding. It is also now available on Hippocampus.org under "Simulations".)

How to Record Your Own Step-by-Step Algebra Problems
This post will help any teacher who wishes to record and post online additional example problems for their students.
(This blog refers to the worked examples for NROC's Algebra 1--An Open Course, Unit 6, Topic 1: Solving Systems of Linear Equations by Graphing . These examples are available at hippocampus.org.)

Strengthening Language Skills While Reviewing Graphing Inequalities
Students first fill in a teacher-created cloze dealing with systems of inequalities. Then, they make and share one of their own.
(The “Topic Text” from which the cloze worksheet was created is currently only available if you have direct access to Algebra 1--An Open Course. However, the systems of inequalities cloze worksheet and key are linked to directly from the blog.)

Virtual Math Manipulatives for Algebra
Interactive math manipulatives and their use are linked to and discussed.
(The math manipulative focused on in the blog illustrates the effects of the “m” and “b” terms on linear equations and appears in the course text. It is from NROC’s Algebra 1—An Open Course, Unit 4, Lesson 1, Topic 3: Proportional Functions and is only available if you have direct access to the course. However, links to publicly available manipulative archives are provided.)

Applying Functions: A Roller Coaster Project
After reviewing functions and their graphs via the online tutorial simulation, “Snowboarding,” students draw a graph representing the hills and loops of a roller coaster. The students use coordinates from their graph to discuss different types of relations (functions, linear functions, etc.). Finally, they create a scale model of a roller coaster, thereby applying their learning to the use of a proportional function in a real world situation.
(The simulation and project referred to are from Unit 3 of NROC’s Algebra 1--An Open Course. A version of the roller coaster project is available through links on the blog post, and the simulation is also now available on Hippocampus.org under "Simulations".)

Introducing Exponents
Exponent rules are introduced. The power of exponents is further explored with activities based on a classic math story in which grains of rice are doubled on each successive square of a chessboard resulting in the last square receiving 2^64 grains of rice.
(This lesson uses the NROC video presentation from Algebra 1—An Open course, Unit 7, Lesson 1, Topic 1: Rules of Exponents, which is now available at hippocampus.org.)

Polynomials--Introducing and Exploring
This blog’s lesson asks students to predict the rules of polynomial addition and subtraction based on their understanding of what a polynomial is. They then share their results and check their predictions.
(This blog refers to recordings from NROC’s Algebra 1—An Open course, Unit 8, Lesson 1, Topic 1: Polynomials, and Unit 8, Lesson 1, Topic 2: Adding and Subtracting Polynomials, which are available at hippocampus.org.)

This lesson reinforces students’ ability to check their work while reviewing both factoring and polynomial multiplication.
(Students use the practice problems from NROC’s Algebra 1—An Open course, Unit 9 - Factoring, Lesson 1, Topics 1, 2, and 3 to develop skills in checking their own work.  These problems are only available to those with direct access to the course.)

CAHSEE and Others -- High School Exit Exam Math Preparation
This blog provides a plan and links to aid preparation for the California High School Exit Exam (CAHSEE), but the links provided are useful for any summative high school math exam.
(The blog links to California state materials as well as recordings from NROC’s Algebra 1—An Open Course and the Khan Academy Collection on Hippocampus.org.)

A Year in Review, Blogs for NROC’s Algebra 1—An Open Course
Now, it’s time to review! This blog post bundles the past year of posts. Which is to say, here you’ll find links (one in each title) leading to my 11 previous blogs. Quick descriptions are provided.
(Wait a moment. This title seems familiar somehow. Oh well, Enjoy! …And if you’re reading this before the end of March in 2012, I hope I might see you at the NROC Member’s Conference.)
