Skills to Review from Algebra 1--2024
Skills to Review from Algebra 1--2024
Factoring Quadratics
Solving Quadratics
Understanding and Using Exponential Functions
Simplifying Rational Expressions
Operations with Rational Expressions
Below you will find a section for each of these skills. It will include valuable links to notes, videos, or other tutorials. Each section will also include a practice worksheet and key.
Feel free to reach out to Ms. Sprigg with questions: nsprigg@dcsdk12.org.
After that is an intro to Algebra II, combining Algebra 1 Skills and beginning Alg II Skills. These skills include:
Function Notation and Evaluating Functions
Intro to Matrices
Solving Two Variable Systems with Matrices and Cramer's Rule
Week 1--Factoring and Solving Quadratics
Week 1--Factoring and Solving Quadratics
This week will be a bit longer, as this is a BIG skill and has many components. Feel free to break up your study/review as you'd like. If you don't need the videos, that will save you a lot of time, as the videos can be long.
There are 5 main types of factoring. (There are others, but these are the essential skills.) Each of the 5 types have a unique video and explanation. The worksheet has ALL of these problems, and an answer key.
Worksheet (each section of 10 problems relates to 1 kind of factoring, answer key at the end)
Factoring and Solving Quadratics are closely related, but not EXACTLY the same. Below is a video to help you understand the difference, and to help you move from factors to actual solutions.
Week 4--Operations With Rational Expressions
Week 4--Operations With Rational Expressions
This week is a review of adding, subtracting, multiplying and dividing. It's a perfect combination of your factoring skills as well as your simplifying skills. Doing this is sure to help keep your memory and ability up to date.
Week 5--Intro to Function Notation and Evaluating Functions
Week 5--Intro to Function Notation and Evaluating Functions
This week is a quick review of the definition of a function, how to identify if something is a function (table, graph, equation, map), and how to evaluate a function.
I reference this video in my own lesson, if you are interested: What is a Function?
Week 7--Matrices and Cramer's Rule
Week 7--Matrices and Cramer's Rule
No new information this week, just another chance to practice Cramer's Rule!
Week 8--Discrete Functions, Domain and Range
Week 8--Discrete Functions, Domain and Range
This week we'll return to functions (out of order because I didn't plan as well), and look at what are discrete functions, and how to evaluate them. We'll also do a quick review on domain and range, as this is an essential understanding for Algebra II.
