Understanding **how to teach decimals** to kids is crucial because decimals can be quite challenging for them to grasp. Unlike whole numbers, decimals introduce a new element – the decimal point – and numbers that extend beyond it. This can feel like learning an entirely new language in mathematics. Why are decimals so tricky for kids? Mainly, it’s because they’re a significant shift from the whole numbers children are accustomed to. Decimals demand an understanding of the numbers and how their position after the decimal point affects their value.

**What are Decimal Numbers?**

Decimal numbers are numbers with a whole part and a fractional part, separated by a decimal point dot. The number on the left of the decimal point is the whole part, and the number on the right is the fractional part. For example, in 5.7, 5 is the whole part, and 7 is the fractional part, which means a little more than 5 but less than 6. Decimals are a way to write numbers that are not whole, helping us to measure and count things precisely.

**3 Intriguing Facts About Decimals**

**Decimals Have Been Around for Centuries:**The concept of decimal numbers has a long history, dating back to ancient civilizations. Today’s system was developed over time, with significant contributions from mathematicians in places like ancient Greece, China, and the Arab world. However, it wasn’t until the 16th and 17th centuries that the decimal system became widely used in Europe, thanks to the work of mathematicians like Simon Stevin.**Decimals and Computers:**In the world of computers, decimals play a unique role. Computers operate using binary code, a system of just two numbers: 0 and 1. When we input decimal numbers into computers, they convert these into binary code.
