Number & Operations in Base Ten - 5th Grade Math

We can use base ten blocks to help us solve this problem. Let's review what our base ten blocks are by using a whole number

When we put this together, we add:

To use base ten blocks to add decimal numbers, we need to think of the base ten blocks a little differently. We think of the hundreds block as one whole. The tens block as tenths because you would need ten of these to make one whole. Finally, the ones block as hundredths because you would need a hundred of these to make one whole:

Let's look at this problem:

First, we want to represent the with four tenths blocks and five hundredths blocks:

Next, we want to represent the with one tenths block and three hundredths blocks:

Now, we want to combine our blocks together:

We can see that we now have five tenths blocks and eight hundredths blocks, which means our answer is

Next, we want to represent the with three tenths block and two hundredths blocks:

Now, we want to combine our blocks together:

We can see that we now have four tenths blocks and seven hundredths blocks, which means our answer is

The tens block as tenths because you would need ten of these to make one whole. Finally, the ones block as hundredths because you would need a hundred of these to make one whole:

Let's look at this problem:

First, we want to represent the with five tenths blocks and six hundredths blocks:

Next, we want to represent the with one tenths block and seven hundredths blocks:

Now, we want to combine our blocks together:

Notice that we have more than ten hundredths blocks. This means we can take ten of the hundredths blocks and make another tenths block:

We can see that we now have seven tenths blocks and three hundredths blocks, which means our answer is

When we add decimals, we can treat it like a normal addition problem, we just need to remember out decimal:

Adding decimals is just like adding regular numbers, you just must remember to bring down your decimal point:

Adding decimals is like adding regular numbers, you just need to remember your decimal:

Adding decimals is just like adding whole numbers. But, you must remember your decimal in your answer.

You start adding on the far right which in this case is the hundredths place. . We have to carry a from the sum above the tenths place and place the other below the hundredths place.

Next, add the tenths place.

The decimal will be carried down and remain between the tenths place and the ones place.

The final addition portion is the ones place.

The final answer is

The tenths place will also be the first digit to the right of the decimal point.

The ones place will always be the first digit to the left of the decimal point.

The hundredths place will always be the second digit to the right of the decimal point.

The hundreds place will also be the third digit to the left of the decimal point.

The thousands place will always be the forth digit to the left of the decimal point.

The thousandths place will alway be the third digit to the right of the decimal.

The tens place will always be the second digit to the left of the decimal point.

The tenths place will always be the first digit to the right of the decimal point.

The hundreths place will always be the second digit to the right of the decimal point.
