Welcome to learning about decimals! Decimals are a special way to write numbers that show parts of a whole. Think of them like fractions, but written in a different way. For example, if we have a pizza cut into ten equal slices and we take three slices, we can write this as zero point three, which is the same as three-tenths.
Now let's learn about decimal place values. Each digit in a decimal number has a special place. The dot is called the decimal point, and it separates whole numbers from parts. To the left of the decimal point, we have ones, tens, hundreds. To the right, we have tenths, hundredths, and thousandths. Each place gets ten times smaller as we move right.
Now let's practice reading decimals out loud. When we read a decimal, we say the number and then the place value of the last digit. For zero point seven, we say seven tenths. For zero point twenty-five, we say twenty-five hundredths. For zero point zero zero three, we say three thousandths. The key is to identify the place value of the last digit.
We can also show decimals on a number line. Between zero and one, we can fit many decimal numbers. Each small mark represents one tenth, or zero point one. Let's mark some special decimals: zero point two is here, zero point five is in the middle, and zero point eight is here. This helps us see how decimals relate to each other and compare their sizes.
Let's review what we learned about decimals. First, decimals are a way to show parts of a whole, just like fractions. Second, the decimal point separates whole numbers from the fractional parts. Third, each place value gets ten times smaller as we move to the right. Finally, we can read decimals, write them, and show them on number lines to understand their value.
