Organizing Data Into Matrices

When algebra 2 students familiarize themselves with organizing data into matrices, they first learn how to identify the different types of matrices, count the number of rows and columns in matrices, as well as judge the order of a matrix. To facilitate these early introductory lessons on matrices, math teachers can employ a variety of […]

In algebra 2, students learn the standard form of quadratic functions and how to differentiate between linear and quadratic functions and become proficient in modeling data with quadratic functions. Learning modeling data with quadratic functions can sometimes seem challenging for students. Luckily, there are ways in which teachers can make this process as smooth as […]

Teaching Relations and Functions

In Algebra 2, relations and functions are among the earliest math concepts that students come across. They learn how to arrange and identify relations and functions, and are able to identify the range and domain of relations. Teaching relations and functions can be challenging, especially if your students have gaps in previous knowledge in this […]

Rational Functions and Their Graphs – Group Activity

Below we have provided the Rational Functions and Their Graphs Group Activity. You will need to download these for the Activity. You will need to have the students count off by fours and assign them each a student number.  Rational Functions Group Activity Directions: Each Group is Given a Rational Function and must: Find and  […]

Algebraic Expressions Worksheet and Activity – Mazing!

This activity is available as a free download. It includes an algebraic expressions worksheet where the students must solve problems that will help then work their way through a maze! Registering on the website also gives access to a ton of Algebra 2 activities. In this activity students are given 15 algebraic expressions that require […]

Properties of Logarithms

Change of Base Formula Your calculator will only do Base 10 (log) and base e (ln). In most cases this is sufficient for real world problems. However, if another base is needed we have to be able to adjust! The best example you can use in class is a CLOCK! A clock doesn’t use either […]

Adding and Subtracting Matrices – Using Rainbows

This is the most important lesson in the Unit on Matrices! The easiest way to teach adding and subtracting matrices is by color coding. Let’s Start Adding and Subtracting MatricesI start with adding two 2×3 matrices. The reason I do not start with 2×2 matrices is because it is easier to show them that the matrices […]

The Nightmare of Exploring Conic Sections

Conics Sections can be a very confusing lesson if you let it be. The best advice I can give to any teacher is to start with the basics of the equation of a circle. Make sure they have mastered h,k form and how changes to the equation transform the shape. Once you are confident they completely […]

Probability of Multiple Events – A Coin and a Card

I love this lesson on Probability of Multiple Events. You get to give your students things they can actually touch. There are many simulators out there that you can use to get them to see the bell curves and all that boring stuff. The part I love is handing my students a deck of cards, […]

Roots and Radical Expressions – Why so Negative?

Students can really struggle with this unit on Roots and Radical Expressions if not taught correctly right away. This is usually the first time that the concept of a math problem having 2 answers ever arises. If you aren’t careful with the way you present this you will lose your students that aren’t big fans […]
