This one page task can be used as a short assessment. It shows the student 6 differential equations and 6 matching slope fields. Students must think "what is the differential equation telling me about the slope of a function?" The slope field "paints" a picture of what the differential equation is describing. By comparing the differential equations and the slope fields, the students match which differential equation matches with each slope field.
It is a great activity to use with the students after they have been briefly introduced to a slope field.
