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.
8th grade / Geometry & measures / Polygons / Interior and Exterior angles / Sum of interior angles
Any polygon with more than 3 sides can be split into a series of triangles by drawing lines between corners. Since we know that the interior angles of triangles sum to 180°, we can calculate the sum of the interior angles of any polygon by multiplying the number of triangles it contains by 180°. A shorthand version of this calculation is to take 2 away from the number of sides of a polygon and multiply that number by 180°.
The formula for calculating the sum of interior angles of a polygon given the number of sides is:
Sum of interior angles = (N - 2) x 180°
(where N = Number of sides and 180° = sum of interior angles of a triangle)
So, for any polygon with 5 sides (pentagon), the interior angles sum to:
3 x 180° = 540°
For a polygon with 10 sides (decagon), the interior angles sum to:
8 x 180° = 1440°
For a polygon with 3 sides (triangle), the interior angles sum to:
1 x 180° = 180°
With our Choose or lose math game you will be practicing the topic "Sum of interior angles" from 8th grade / Geometry & measures / Polygons / Polygons. The math in this game consists of 16 questions that ask you to calculate the sum of the interior angles for each of the given polygons.
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.
UXO * Duck shoot * The frog flies * Pong * Cat and mouse * The beetle and the bee
Rock fall * Four in a row * Sow grow * Choose or lose * Mix and match
Our CHOOSE OR LOSE game asks the learner to click on the correct answer from a selection of possible answers before the clock runs down.
