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
Kindergarten / Subtraction / Subtracting numbers / Subtraction: bridge through 10
In this topic we are going to look at taking away (subtracting) a single digit number like 4 or 7 from a double digit number like 12 or 15 (this is sometimes called 'bridge through 10' because you are counting down from double digits to single digits through the number 10). This is a little bit harder than subtracting single digit numbers but not much harder. So, how can we work out the answer to the following sum :
12 - 7
We know we can subtract numbers by counting down from the first (bigger) number by the same number of steps as the second (smaller) number. So to subtact 6 - 3, we start with 6 and count down three places to 5 then 4 then 3, and 3 is the answer.
When we are subtracting from a double digit number, we do the same thing. So, for 12 - 7, we are going to start with 12 and count down seven places - so, 11, 10, 9, 8, 7, 6, 5. So we can say :
12 - 7 = 5
If you find counting down hard, a different way to work out the sum is to start with the smaller number and count up to the bigger number, and the number of steps you take will be the answer. So if we have the sum 9 - 5, we can count up from 5: to 6, then 7, then 8, then 9. So that was 4 steps and the answer is 4. For 12 - 7, we would start at 7 then :
The number of steps from 7 up to 12, which is the answer, is 5
Another question from the topic is :
17 - 8
So let's use our counting up method. We start at 8, plus 1 to 9, plus 1 to 10, plus 1 to 11, plus 1 to 12, plus 1 to 13, plus 1 to 14, plus 1 to 15, plus 1 to 16, plus 1 to 17. How many steps was that? It was 9 steps so we can say :
17 - 8 = 9
With our UXO math game you will be practicing the topic "Subtraction: bridge through 10" from Kindergarten / Subtraction / Subtracting numbers. The math in this game consists of 16 questions that ask you to subtract a single-digit number from a double-digit number by counting down through 10.
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.
