Game: FOUR IN A ROW
Aim: To get four symbols in a row
Method:
Choose a square and click on it. Click on the correct answer to the question in the box that appears. If you are right the square is replaced by a tick. Continue until you have won 4 in a row...
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 Four in a row 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.
The game will reinforce the math you have chosen to learn by getting you to match the question to the correct answer.
