I created a Jamboard with equations on each slide.  Students are to model equations.  The opening slide has the key for all subsequent equations.   A red counter represents a negative integer, a yellow counter represents a positive integer, and a grey rectangle represents the variable.    After students correctly model the equations, they may be asked to solve them.  Students should use the rectangle and red/yellow counters to solve the equation.  This activity was created due to students being virtual and unable to physically move the counters in the classroom.  Students may work independently or collaboratively.  https://jamboard.google.com/d/13T40ubvlB4-JX98Jwze4DItHJEqmCL63qEBz2ALIsxY/copy?usp=sharing
