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
2nd grade / Fractions / Fractions and decimals / Order fractions from smallest to largest
Knowing which fraction is biggest or smallest is not always obvious. If we compare fractions that have the same number on the bottom (the denominator) like β , β and β , then the bigger the number on the top (the numerator) the bigger the fraction is.
If we compare β , β and β , we can see that all those fractions have the same denominator of 5. The numerators are 4, 3 and 2. So we can say that to arrange those fractions in order from smallest to biggest will be :
β β β
There is another type of fraction that we need to talk about, unit fractions.
A unit fraction is the name for a fraction where the number on the top is a 1.
So Β½ is a unit fraction and so are β and β but β is not because it's numerator is not 1, it is 2.
Arranging unit fractions from smallest to biggest is not as easy as our first example. If we think about the two most common unit fractions, ΒΌ and Β½, we will see why. Which is bigger, ΒΌ of a cake or Β½ a cake? The answer is that Β½ a cake is bigger than ΒΌ of a cake even though the denominator of Β½, which is 2, is smaller than the denominator of ΒΌ, which is 4.
So, when we are asked to arrange fractions which are unit fractions, we have to remember that we need to compare the denominators, but that the fractions with the biggest denominators are the smallest fractions. If we are asked to arrange β β β in order from smallest to largest, we compare the denominators and order the fractions with the bigger denominators first and those fractions with the smaller denominators last. Arranging β β β in order from smallest to largest gives :
β β β
With our Mix and match math game you will be practicing the topic "Order fractions from smallest to largest" from 2nd grade / Fractions / Fractions and decimals. The math in this game consists of 16 questions that ask you to re-arrange each set of fractions so that they are listed from smallest to largest.
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?
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
There are 5 blocks that need putting away to tidy the play room. Drag (they are heavy...) the blocks to the correct boxes.
