Learning Objective
Students will be able to apply decimals to real-world situations.
In this lesson, we'll explore how to apply decimals to real-world situations. Mathematical thinking develops logical reasoning and problem-solving abilities.
A decimal is another way to show parts of a whole, using a decimal point. The digits to the right of the decimal point show tenths, hundredths, thousandths, and so on. For example, 0.5 means 5 tenths (which equals 1/2). The number 3.25 means 3 whole ones plus 2 tenths plus 5 hundredths. Decimals are useful for money, measurements, and precise calculations.
As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.
Take notes on key points and make connections to what you've already learned in previous lessons.
