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
4th grade / Fractions / Subtract fractions / Subtract mixed fractions with borrowing
A mixed number has a whole number part and a fraction part. Sometimes when you want to subtract 2 mixed numbers, you will find that the fraction part of the second number is greater than that of the first. For instance, in the sum 2⅓ - 1⅔ the fraction part of the second number is greater than the fraction part of the first number.
So one way to solve such a sum is to borrow 1 from the first whole number (which is reduced by 1) and add it to the fraction part so that the fraction part of the first number becomes greater than the fraction part of the second number. In our example, 2⅓ - 1⅔ becomes:
Now you can subract the fraction part first, and then the whole numbers to arrive at the solution.
A different way to think about this sum (and any similar sum where the denominators of the fraction parts are the same) is to count up from the second number to the first. So in our example above, counting up from one and two thirds to two gives us one third, and then we need another third to get to the first number two and a third, so the difference between the 2 numbers is two thirds.
With our UXO math game you will be practicing the topic "Subtract mixed fractions with borrowing" from 4th grade / Fractions / Subtract fractions. The math in this game consists of 14 questions that ask you to use borrowing to subtract mixed fractions.
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.
