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

Due to the fact that our number system is base 10, dividing decimal numbers by powers of 10 is relatively simple. The digits of the number move around, and there are maybe zeros to add or remove, but the other digits all stay the same. Remember that when we divide numbers by any number greater than 1 they get smaller so check this once your done.
Let's get our terms straight.
dividend ÷ divisor = quotient
237.4567 ÷ 1000 = 0.2374567
So for the sum 237.4567 ÷ 1000 = 0.2374567,
When the divisor is 10 the quotient is 10x smaller than the dividend. When the divisor is 1000 the quotient is 1000x smaller than the dividend.
Write the number to be divided down. Keep the digital point still and move all the digits of the number to be divided to the right relative to it. If we are dividing by 10, all the digits move 1 place. If we are dividing by 100, all the digits will move 2 spaces, and for dividing by 1000, it is 3 digits.
237.4 ÷ 10 = 23.74
237.4 ÷ 100 = 2.374
237.4 ÷ 1000 = 0.2374
Another way of thinking about it is to keep the number static and move the decimal point - when the divisor is 1000 by three places to the left, one for each of the zeros in 1000.
Dividing by 10 is the same as multiplying by the inverse of 10 which is 1/10 or 0.1, and dividing by 100 is the same as multiplying by it's inverse 1/100 or 0.01.
With our Mix and match math game you will be practicing the topic "Divide decimals by 10 100 1000" from 6th grade / Number / Decimals / Decimals. The math in this game consists of 16 questions that ask you to divide by powers of 10 up to 1000 by moving the digits the correct number of columns to the right.
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?

There are 5 blocks that need putting away to tidy the play room. Drag (they are heavy...) the blocks to the correct boxes.
