Mastering Decimals: Key Concepts
Before diving into practice problems, let's ensure your child understands the following key concepts:
Understanding Decimals
Decimals are numbers that have a part greater than 1 and a part less than 1. The decimal point separates the whole number part from the decimal part. For example, in 0.75, 0 is the whole number, and 75 is the decimal part.
Place Value of Decimals
The place value of a digit in a decimal is determined by its position. The first digit to the right of the decimal point is in the tenths place, the second digit is in the hundredths place, and so on. For instance, in 3.14, 1 is in the tenths place, and 4 is in the hundredths place.
