### Algebra Word Wall - print and digital

One year, I found myself drawing linear graphs and tables on our whiteboard over and over and over again. My students needed constant refreshers back to these algebra 1 topics from the nonlinear functions we were learning about in class. I wasted so much time drawing those graphs. So the next summer, I put together parts of an algebra word wall to cut down on all the drawing.

I posted photos of the graphs and tables that I had made on social media and immediately heard from teachers who wanted the references for their own algebra classrooms. Fast forward a bunch of years, and this algebra word wall now includes a printable color version, a printable black & white version, a no-prep version built in Google Slides and Spanish vocabulary.

With references for slope, y-intercept, x-intercept, origin, grid, graph, table, x and y axis, domain and range, increasing and decreasing, quadratics, graphing exponential functions, linear equations, linear inequalities, systems of equations, systems of inequalities, parallel and perpendicular lines on the coordinate plane, compound interest, difference of squares, complete the square, Quadratic Formula, fractional exponents, term, expression and equation, algebraic and geometric sequences, this word wall is a great support for an algebra curriculum.

In this post, I want to show you some of its pieces.

Here is the very first part I made of the algebra word wall. I made this part for my algebra 2 classroom so that we could make connections between x-intercept and y-intercept in linear equations and the zeros and y-intercepts of the nonlinear functions we were learning in class. It shows the math vocabulary origin, grid, graph, y-intercept and x-intercept. I have always found examples to work really well with my students, especially my students who struggle with reading for any reason. So this section shows the algebra vocabulary through the example y = 2x - 6.

Is it a factor, term, expression, equation? This section shows these vocabulary words as well as exponent, constant, coefficient and variable through more examples. I have found examples helpful for students, especially students who struggle with language for any reason. Being able to apply an example to a new problem is a skill that needs to be developing in kids and one that comes in handy during problem solving.

Like most of the later additions to this word wall, this section on compound interest was a teacher request.

There's an exponential functions section in the word wall that is a lot like the linear section. It helps students compare exponential and linear functions and how they each grow. The quadratic functions section has a lot of math vocabulary going on! You can choose to display everything at once or add pieces as you progress through the unit.

I love how "difference of squares" is literally one square removed from another.

This section links the process of completing the square and standard, vertex and factored form quadratics.

All of the photos here are hand-colored, but I also added color versions of all the pieces not too long ago. So if you have access to a color printer, everything will print in about the colors I used to color the pieces in these photos.

Solving systems of equations through graphing, elimination and substitution with links to their graphs are included. Algebraic and geometric sequences were another more recent addition from  teacher request. And of course, quadratics. The different forms, the Quadratic Formula, difference of squares, completing the square, zeros, vertex, second difference. I also added domain, range, increasing, decreasing and function notation into this section.

The digital version was a 2020 addition. I added digital versions to all of my math word walls to support students who were suddenly learning from home. My favorite way to share the digital versions is by sending the word wall in /present mode. I wrote a short post explaining how to send digital word walls to students here.

The algebra word wall, along with all of my print and digital algebra activities, are all included in this Algebra 1 Activities Bundle
