This resource is a Google Sheet containing 20 one-step equations. There are 3 columns; Column 1 gives the equation. Column 2 asks for the operation required to solve the equation. Column 3 is for the solution. The solution box will turn green if it's correct so students will get immediate feedback. There is also a 2-step equation at the end for students to try if they want a challenge. I use this as classwork to review with my 8th graders and it takes most of them about 15 minutes to complete.
This is a reference sheet for finding mean, median, and mode. It is hand-drawn and shows an example for each. I just drew it up for my students and I hope you find it useful for your own class!
