Mystery Area

This is intended to be a warmup activity for Desmos Central Park -- it prepares students who need an introduction to representing situations by writing expressions with variables. I plan to use this activity after Pool Border and before Central Park. It provides fairly robust hints for student wrong answers, so most students can work through this in pairs and get their answers checked by the computer, leaving the teacher free to work with the few students who need teacher support to access the lesson. For Virginia Algebra 1, all students should do Pool Border, most students should do Mystery Area, and some students should do Central Park. --Pool Border is here: https://teacher.desmos.com/activitybuilder/custom/58798fc7e338613f05a42feb --Central Park is here: https://teacher.desmos.com/centralpark
