Group Activities for Solving One & Two Step Equations

I am on my third day of student teaching and cannot be more excited!!

I am planning lessons for the unit that I will begin teaching in a few weeks and I am having trouble finding group activities to supplement the lesson and further understanding. 

The unit we are covering includes the following:

Solving One Step Equations (+, - , * and /)

Solving Two Step Equations

Solving by Distribution and Combing like Terms

Solving Equations: Clearing Fractions

Solving Equations (with one variable)
