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
3rd grade / Comparing numbers / Order decimal numbers / Decimal numbers: descending
To arrange decimal numbers in descending order we need to define 2 things:
A decimal number has two parts: the whole number part and the decimal part. The whole number part comes before the decimal point, and the decimal part comes after it. For example, in the number 5.32, the whole number part is 5, and the decimal part is 32.
To arrange numbers in descending order is to arrange the numbers from biggest on the left to smallest on the right. In descending order, the numbers 3, 2, 4, 1 are 4, 3, 2, 1.
Step 1: Compare the whole numbers first. When you're trying to arrange decimal numbers, start by comparing their whole number parts. The larger the whole number, the larger the decimal number. For example, 4.1 is bigger than 3.8 because 4 is bigger than 3.
Step 2: Compare decimal parts if the whole numbers are equal. If two decimal numbers have the same whole number part, then you need to compare their decimal parts. Look at each digit in the decimal part, starting from the left, and compare them. The larger the digit, the larger the decimal number.
For example, let's compare 4.09 and 4.15: The first digits are 0 (from 4.09) and 1 (from 4.15). Since 1 is bigger than 0, 4.15 is bigger than 4.09 even though it's second digit is smaller.
Let's arrange these numbers in descending order: 3.6, 1.15, 3.45, 1.80, 2.2.
First, arrange them by whole number parts: 3.6, 3.45, 2.2, 1.15, 1.80.
Now, compare the decimal parts of numbers with the same whole number part: 1.80 is bigger than 1.15, and 3.6 is bigger than 3.45.
The correct descending order is: 3.6, 3.45, 2.2, 1.80, 1.15.
With our UXO math game you will be practicing the topic "Decimal numbers: descending" from 3rd grade / Comparing numbers / Order decimal numbers. The math in this game consists of 16 questions that ask you to choose the correct descending order for these lists of 4 decimal numbers.
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.
