This choice board has six project-based tasks based on solving systems of linear equations (1 page handout in a grid). Students choose three of the six tasks to complete. This is a great way to assess at the end of a unit on systems.
I have also included stations - style cards describing each task. You can use this format instead if you choose to have students rotate through all six tasks in centers, or learning-stations (6 pages with tasks listed in large print - meant to be laminated and placed at each station).
Take a look at the preview file to see what the tasks are.
