We are usually mid-linear functions in October, so I created this matching activity to bridge our work with graphing, tables and slope-intercept form with our recent introduction to point-slope form. We also needed to really get deep into the unit-rate nature of slope and this activity really helped students make connections to that aspect. While many remember "rise over run" they forget to tie it back to independent and dependent quantities.
I LOVE CARD-SORTS!! But so much of what is out there doesn't require careful analysis - one point on each card is typically enough to complete the activity - not the case with mine :) all y-intercepts are the same and data tables, graphs and equations must be carefully analyzed to ensure a good match.
Students start with a verbal scenario and match it to tables, graphs, two versions of equations and two interpretations of slope. They use the models to solve related questions and write to explain their understandings.
Can be used as mid-unit activity, formative assessment or even as linear review in later coursework. I plan to use this again next year twice. Once as described above and then again to introduce systems of equations by allowing students to graph all in one and explore solving algebraically and graphically.
