This can be used as a one or two-day lesson on solving absolute value equations. There is also a YouTube video included that can be used for yourself, with students, or perfect for a sub plan with a teacher not prepared to teach Algebra 1. and we all know that our subs rarely ever know Algebra 1 material. #SorryNotSorry

I love this activity so much! This package includes 4 files: 1) Desmos Investigation that helps students learn how to graph lines, inequalities, circles, and introduces domain and range. 2) Answer Key for the Investigation. 3) Additional graphing tips that show various functions such as absolute value and quadratic that will help student create art with their graphing calculators. It also details how to write equations for horizontal and vertical lines. My students have always struggled with tha

One of the best activities if you set it up correctly. Students are creating their own mystery number problems, and the rest of the class will solve them. I call it a scavenger hunt with my students, but I call almost everything in which they are getting out of their seats a scavenger hunt. Leave yourself time to check the mystery number problems that the students create. The activity is only as good as the clarity of their problems. I also highly suggest running through a couple of problems of

This is a great review sheet for students to practice solving quadratic equations, with a word problem where they will need to multiply binomials. Students can use any method to solve. However, these were selected for a variety of factorable equations. You may want to remind students to set equations to zero whether they factor or use the quadratic formula.

This is a two-part activity. First, students graph 8 different linear inequalities. Then they match it up with graphed linear inequalities to find the right answer, or to correct their mistake. I recommend handing out one page at a time unless you want students to focus only on writing linear inequalities when given a pre-made graph.

This is fun for students to create their own arithmetic sequences and to solve for their classmates' sequences as well. I find this to be really helpful in writing the rule of the sequences in y = mx + b format.
