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
3rd grade / Shapes / Properties of 2-D shapes / How many lines of symmetry
Lines of symmetry are imaginary lines that you can draw through a shape that divide the shape into two halves that are exact mirror images of each other. Different shapes have different numbers of lines of symmetry:
Square: A square has four lines of symmetry - one vertical, one horizontal, and two diagonal lines. Each line of symmetry divides the square into two halves that are mirror images of each other.
Rectangle: A rectangle has two pairs of opposite sides of equal length and four right angles. It has two lines of symmetry - one vertical and one horizontal.
Triangle: The number of lines of symmetry a triangle has depends on the type of triangle it is. An equilateral triangle has three sides of equal length and three equal angles. It has three lines of symmetry - one vertical and two diagonal lines. An isosceles triangle has two sides of equal length and two equal angles. It has one line of symmetry - the line that goes through the midpoint of the base and bisects the opposite angle. A scalene triangle has no lines of symmetry.
Kite: A kite has one line of symmetry - the line that goes through the midpoint of the shorter diagonal and bisects the longer diagonal.
Pentagon: A regular pentagon has five sides of equal length and five equal angles. It has five lines of symmetry - one vertical, one horizontal, and three diagonal lines. Regular shapes with more sides like hexagon and octagon have the same number of lines of symmetry as they have sides. So a regular octagon has 8 lines of symmetry.
In this topic you are shown a series of diagrams of regular 2D shapes. You must give the number of lines of symmetry for each shape.
With our Mix and match math game you will be practicing the topic "How many lines of symmetry" from 3rd grade / Shapes / Properties of 2-D shapes. The math in this game consists of 24 questions that ask you to identify the number of lines of symmetry each shape has.
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?

There are 5 blocks that need putting away to tidy the play room. Drag (they are heavy...) the blocks to the correct boxes.
