Game: MIX AND MATCH
Aim: Drag question blocks to answer boxes
Method:
Drag the question block over the right answer box to tidy up the play room. Points are added and taken away automatically.
Click the answer boxes to hear the answer for each box. You must answer 5 questions correctly to complete the game
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 Mix and match 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.
In this game we are in a room with lots of toys - and the room needs clearing up - you need to put the play blocks back in the right boxes to tidy the room and win the game...but which is the right box for each block? Well, you can work that out by comparing the question on the block with the math answer on each of the boxes - you should drag the question block into the box whose math answer matches the picture question.
You can listen to the spoken math answer by clicking on the individual boxes. There are 5 blocks to clear up - but if you put them in the wrong boxes, there will be more... Anyway, tidy is good and practicing math is better so start now and see how you get on...
This game reinforces the math you learned or revised in the lesson by asking you to match each question to the correct answer. If you are older you may not like the childish reference to toys, but don't worry - there are other games to play, and who knows - you might like a trip down memory lane?
