Game: UXO
Aim: Knock out the targets, avoid the bombs
Method:
Click or tap and hold to destroy the objects while avoiding the bombs. When you knock out all 10 targets, you must answer the question to continue to the next level. There is a time limit of 30 seconds to get all 10 targets or you lose 50 points.
Scoring is :
Hit target : +10
Hit bomb : -5
Right answer : +50
Wrong answers : -20
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 ⅖, ⅗ and ⅘, then the bigger the number on the top (the numerator) the bigger the fraction is.
If we compare ⅘, ⅗ and ⅖, 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 :
⅖ ⅗ ⅘
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 ½ is a unit fraction and so are ⅐ and ⅛ but ⅖ 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, ¼ and ½, we will see why. Which is bigger, ¼ of a cake or ½ a cake? The answer is that ½ a cake is bigger than ¼ of a cake even though the denominator of ½, which is 2, is smaller than the denominator of ¼, 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 ⅕ ⅙ ⅐ 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 ⅕ ⅙ ⅐ in order from smallest to largest gives :
⅐ ⅙ ⅕
With our UXO 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.
UXO is a fun game to learn math where you attempt to knock over all the target objects while avoiding clicking / tapping on the bombs.
After each level, win an additional 50 points by correctly answering a math question from your selected topic. Wrong answers lose you 20 points but you can answer multiple times. Each level lasts 30 seconds: if you haven't cleared all the targets in that time, you lose 50 points. High scores can be added to the UXO leaderboards.
