Game: CHOOSE OR LOSE
Aim: Choose the right answer; beat the clock
Method:
You start the game with 50 points. Each question has 2 to 4 answers. Select the correct answer before your time runs out to score points. Right answers are +10, wrong answers are -2, out of time is -5.
This is a timed game. Your final score is equal to the total score minus time taken.
7th grade / Geometry & measures / Polygons / Interior and Exterior angles / Exterior angles of regular polygons
The exterior angle of a polygon is the angle made by one side of the polygon and the extension of the next side of the polygon. By applying the angles on a straight line rule, we know that the interior angle plus the exterior angle sum to 180°. The sum of the exterior angles of polygons is always 360°.
This topic deals with regular polygons. Regular polygons have equal length sides and each of their interior angles is identical. Examples of regular polygons are equilateral triangle, square, regular hexagon, etc. Because their interior angles are identical, their exterior angles are also identical. The formula for calculating the exterior angle of regular polygons is:
Exterior angle = 360° / n
(where 360° = total of exterior angles and n = number of sides)
So, for a regular 3 sided polygon (an equilateral triangle), the exterior angle is:
360° / 3 = 120°
For a regular 4 sided polygon (a square), the exterior angle is:
360° / 4 = 90°
For a regular 5 sided polygon (a regular pentagon), the exterior angle is:
360° / 5 = 72°
With our Choose or lose math game you will be practicing the topic "Exterior angles of regular polygons" from 7th grade / Geometry & measures / Polygons / Polygons. The math in this game consists of 16 questions that ask you to use the number of sides to calculate the exterior angles for each regular polygon.
Our CHOOSE OR LOSE game is a simple activity to help secondary math learners and will improve the speed at which you can solve problems in the given topic. It does not rely on the learner typing in the answer. Rather, the learner must choose the correct answer from a list of 2, 3 or 4 similar answers.
CHOOSE OR LOSE encourages faster problem-solving for common and vital secondary math topics. CHOOSE OR LOSE is a timed game with a leaderboard for each topic at each of the 4 levels on offer. You can play the game with or without audio and robots.
