On each card, students first determine the slope shown in 2 representations (table, graph, set of ordered pairs, equation*). Next, they either add, subtract, multiply or divide these slope values (based on what their card says to do) to see if the result matches the check number in the lower right corner of the card. Chances are if the check number matches, the rates of change were found correctly!
This activity is self-checking, giving students that instant feedback they love.
Includes 20 task cards that print 4 per page. The cards vary in difficulty so that all students can work at their own level. *Cards 11-20 include equations in standard form, whereas cards 1-10 only include graphs, tables and ordered pairs.
Two versions of the student answer sheet are included for differentiation. One version has spaces for all 20 cards to be answered. The second version has spaces for just the first 10 cards to be answered, if you'd like a shorter activity. The answer sheet also asks students to determine which representation on each card shows the greater rate of change. Answer key included.
I'm currently making more of these self-checking activities. You can see the list here: Solve 'n Check activities
