How to round decimals to 1 decimal place (1 dp)
Rounding is a helpful technique that makes numbers simpler and easier to work with. By rounding, we find a number that's close to the original number but not as precise. This makes it more convenient for estimating and solving problems.
When rounding decimals to the nearest tenth (1 decimal place, 1 dp), we look at the second decimal place (the hundredths column) to help us decide if the first decimal place (the tenths) should stay the same or go up by one. The rules for deciding are:
- If the second decimal place (hundredths) is 5 or greater (5, 6, 7, 8, or 9), round the first decimal place (tenths) up by one.
- If the second decimal place (hundredths) is less than 5 (0, 1, 2, 3, or 4), the first decimal place (tenths) stays the same.
For example, what is 3.24 rounded to 1 decimal place?
Look at the second decimal place (hundredths): it's 4, which is less than 5. So, the first decimal place (tenths) stays the same. The rounded number is 3.2.
What is 7.681 rounded to 1 decimal place?
Look at the second decimal place (hundredths): it's 8, which is 5 or greater. So, we round the first decimal place (tenths) up by one. The rounded number is 7.7.
In this topic you are asked to round decimal numbers to 1 decimal place. The numbers range from 22.93 to 55.5423.
With our Mix and match math game you will be practicing the topic "Round to 1 decimal place" from 4th grade / Decimals / Round decimals. The math in this game consists of 16 questions that ask you to round each of these decimals to the nearest 1 decimal place (1 d.p.).
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?
