Use this short PowerPoint presentation on equations and inequalities to review, teach, or assess your students abilities to write equations and inequalities from a situation written in words or shown on a number line. Students will also draw a number line to show the solution to an equation or inequality. Included in the presentation are 9 different situations for students to show you their mastery or for you to use to teach/review with them. My students use their whiteboards to show me their understanding of inequalities and equations when I use this presentation. They always enjoy it.
