This PDF includes 56 ‘Interior Angles of Polygons’ task cards formatted as 4 cards per page with an attractive border. Cards’ difficulty level progresses from finding the measure of one missing angle to applying algebra skills to solve for x and then substituting the solution to calculate angle measures.
Each page of cards, 4 cards per page, presents a similar topic so that pages can easily be printed and grouped for notes or assignments. There is also enough white space on each card for students to show their work.
The first set of 28 includes QR coded answers so students can self-check their work by scanning the code using an iPad, iPhone, or tablet with one of many free QR code scanning apps. QR codes are ‘text only’ so no internet access is required.
The second set of 28 have the same questions as the first set but include no QR code, allowing for a wider range of applications by the teacher.
Topics for each set of 28 task cards includes:
- 12 Cards: Interior angles of a triangle
- 8 Cards: The interior angles formula (n-2)180
The sum of the measures of different n-gons
What polygon, if any, has a specific angle total
Using the formula to solve for x and find missing angle measures
- 8 Cards: Interior angles of polygons (quadrilateral, kite, pentagon (2), hexagon (2), heptagon, octagon)
- Enlarge and use as a warm up/bell ringer activity.
- Print, number, and post the cards around the room to get students up and moving.
- Print multiple pages on one to use as notes.
- Use as a Ticket Out activity.
- Utilize throughout the year to review/reteach/retain previous concepts.
- Post cards online for extra credit, review, or at home practice.
