Decimals are a way to represent numbers that have a fractional part to express values between whole numbers. They are written with a decimal point, separating the whole number part from the fractional part.

Let me tell you an exciting story about Lily and Emma to help you understand what decimals are all about.

Lily and Emma were talented bakers who loved making delicious cakes. One day, they decided to make a beautiful chocolate cake together. While preparing the cake batter, they needed to measure the ingredients very precisely. They used a special measuring cup that had markings on it to help them get the right amount.

Now, imagine Lily pouring 1 cup of flour into the bowl. The measuring cup showed that the flour reached exactly up to the line marked “1.” This is a whole number, representing a complete cup of flour.

Next, Emma had to add ½ cup of sugar. She looked closely at the measuring cup and noticed a small line halfway between 0 and 1. Emma carefully poured the sugar until it reached that line. This line represents the fraction half (½), which is less than a whole cup.

So, when Lily measured 1 cup of flour, it was like saying 1 whole unit (or 1.0). And when Emma measured ½ cup of sugar, it was like saying 0.5 units, representing a part of the whole cup.

In simple terms, Decimals are helpful when we need to express values that are in-between whole numbers. They allow us to be more precise with measurements and represent fractional amounts.

Especially when dealing with measurements, money, or any situation where we need to express values between whole numbers.
