The two sets of cards (AB and BC Calculus Review Task Cards) included in the bundle each contain 45 questions that review the entire two courses.
The AB cards are separated into three categories based on the three big ideas: Limits, Derivatives, and Antiderivatives.
The BC cards are separated into four categories based on the four big ideas: Limits, Derivatives, Antiderivatives, and Series.
When students have recorded their solution to each question on the student recording sheet, they can then use the QR codes to view a complete solution to that question. The solutions model the type of thinking students should use on solving each question.
In my store you will also find the AB/BC Calculus Review Task Cards BUNDLE. That set is identical to this set, but this set has QR codes for each question.
