2. Tennessee State Curriculum 0406.4.3 Classify angles and triangles as obtuse, acute, or right. SPI 0406.4.4 Identify acute, obtuse, and right angles in 2-dimensional shapes.

3. Directions The students will be divided up into 2 teams (evens and odds) The students from each team will take turns answering their questions. The students will get 2 minutes to discuss the answers with their team before giving the final answer. If they get the answer right, they will get the amount of points shown on the slide. If the answer is wrong, the opposing team gets a chance to answer the question and steal points. It is the teams’ responsibility to keep up with the points earned.

4. Score Card Directions: Use the score card to count up the number of points you’ve earned. If you get the answer correct circle the points. Put your final score in the center of your board. 1 5 points 2 5 points 3 5 points 4 5 points 5 10 points 6 10 points 16 20 points 7 10 points 15 20 points 8 10 points 14 20 points 13 20 points 12 15 points 11 15 points 10 15 points 9 15 points
