Math Practice for Decimals

Decimals Don’t Have to Be Confusing when you Practice Math

Working with decimals is very confusing for most people, children to adults. This confusion can become even overwhelming or paralyzing when they are taking a timed test, so it is important to prepare them as much as possible for their test to give them the confidence that they need. Math Practice with hints and tips to help them deal with decimals can go a long way to helping them to do their best on their test and on their schoolwork from now on. What are some decimal tricks that you can share with your child?

Organize your numbers
When doing any sort of math with decimals, it is important to line up the numbers according to the decimal point. All the solders (numbers) need to be lined up behind the cannon (decimal) and all the cannons should be lined up, as the solders should be lined up. Here is an example:

By lining up your cannons and soldiers, you will be able to help them win their battle by solving them. Add and subtract them as you would a problem without decimals. Just bring down the cannon into its proper place.

Rounding decimals
This can be quite a confusing concept for kids to learn, but it is an important tool, as decimals can keep going, going, and going. You first have to help them determine what place that they are rounding to. This is normally listed in their problem. For example, the tenths, hundredths, thousandths, etc. To help them with rounding, explain that if the number is above 5, then it rounds up and below 5, it will stay the same. Here is an example:

Rounding to the hundredths:
26.677 becomes 26.68
39.432 becomes 39.43
67.359 becomes 67.36

Rounding to the thousands:
43.7789 becomes 43.779
23.4222 becomes 23.422

You look at the number after the point where you are rounding (the bold numbers in the examples) to determine if you increase the number or not.

Count the numbers
When you are multiplying two numbers with decimals, it may seem even more confusing, but it doesn’t have to be. Look at the example below.
.05 x .14 (looks confusing doesn’t it?) Try:
5 x 14 (that looks easier) and then count the numbers before the decimals points in the original problem, which is four. This means that your answer needs to have four places before the decimal point. The answer of the easier problem is 70, but counting decimals means that the answer to the original problem is 0.0070 . See the four places before the decimal? That is the placeholders from your counting in the original problem.

Decimals can make even an adult scratch their head in confusion, so you want to make your child as comfortable as possible with the process of working with decimals. This will take practicing different problems with them time and time again. Math practice is the only way that you can help your child gain confidence with decimals and allow them to do their best on their timed tests. Practice rounding, adding, subtracting, multiplying and dividing to ensure that they will be as prepared as possible. Your child will thank you for it.
