Lesson 3: Digits to the Left and Right
During this lesson, you began looking at decimal numbers and how they fit into our overall place value system. During the next lesson, you'll dive more deeply into decimals and extend what you already know about them.
Questions to Discuss
- In terms of value, how much more is the hundreds place than the tens place? (10 times more)
- In terms of value, how much less is the hundredths place than the tenths place? (1/10 less)
- What happens to the decimal point when you multiply by 10? (it moves to the right)
- What happens to the decimal point when you divide by 10 or find one-tenth of a decimal number? (it moves to the left)
- When might it be important in the real world to understand the values of digits in different places? (examples include buying something expensive, comparing batting averages or other sports statistics, reading nutritional information)
Things to Review
Review that a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left
