If you are looking for a hands-on activity that will help students remember all the information on a unit circle this could be the one you are looking for.  Students find the radian measure, angle measure, and coordinates for 16 points around a unit circle by using right triangles.

Here are four similar products available in my store.  Students understand slope better when they can visualize the points on the line.  These four products have identical questions but some of the questions have the points graphed, while others require the students to product the graph.  With two of the products students can confirm their solutions using the QR Codes.   Geometry-Slope-Task-Cards-without-Graphed-Points-and-with-QR-Codes

Here is a great activity for after you have taught your students all the ways to solve a quadratic equation.  The set of 28 task cards (7 sets of four cards) focus on the various techniques for solving a quadratic equation:
1.   Solve Quadratic Equations using Square Roots
2.   Solve Quadratic Equations using Square Roots in Two     Steps
3.   Solve Quadratic Equations by factoring (a=1)
4.   Solve Quadratic Equations by Factoring (a≠1)
5.   Solve Quadratic Equations by Completing the Square
6.   Solve Quadratic Equations with the Quadratic Formula
7.   Solve the quadratic equation using any method.
 A full set of solutions are included.

Here are six sets of task cards that you can review major ideas you have covered in Algebra I.  They all refer to 7 of the standards in the Common Core State Standards in Algebra I.
