Game: MIX AND MATCH
Aim: Drag question blocks to answer boxes
Method:
Drag the question block over the right answer box to tidy up the play room. Points are added and taken away automatically.
Click the answer boxes to hear the answer for each box. You must answer 5 questions correctly to complete the game
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 Mix and match 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.
In this game we are in a room with lots of toys - and the room needs clearing up - you need to put the play blocks back in the right boxes to tidy the room and win the game...but which is the right box for each block? Well, you can work that out by comparing the question on the block with the math answer on each of the boxes - you should drag the question block into the box whose math answer matches the picture question.
You can listen to the spoken math answer by clicking on the individual boxes. There are 5 blocks to clear up - but if you put them in the wrong boxes, there will be more... Anyway, tidy is good and practicing math is better so start now and see how you get on...
This game reinforces the math you learned or revised in the lesson by asking you to match each question to the correct answer. If you are older you may not like the childish reference to toys, but don't worry - there are other games to play, and who knows - you might like a trip down memory lane?
