Above Average Math

I created this escape room as a back to school activity, but it really can be used any time of the year. There are 5 math challenges: 1. multi-step equation 2. word problem with variables 3. number sequence 4. equations in two variables 5. quadratic equation Solving each problem provides a number to the "code" that will unlock the classroom door. This can be used as a Bell Ringer or an Exit Ticket. It is a way to see what your students know/remember from the summer off or after y

Teaching your students how to solve a system of equations using matrices? THIS is the lesson you want to give! Included is a PowerPoint lesson, complete with animation and answers, that will guide your students into setting up a coefficient matrix, then an augmented matrix, and ultimately reduced row echelon form of the matrix. Prior knowledge on what an identity matrix is has been briefly included as a reminder. Prerequisite knowledge (not included in this lesson): matrix addition and sub
