Objective
By the end of this lesson, you will be able to represent and compare decimals up to 2 decimal places using place value.
Materials and Prep
Materials: Paper, pencil
Prep: Make sure you understand place value and how to read and write decimals.
Activities
1. Decimal Art: Create a fun drawing where you use decimals to represent different parts of the picture. For example, use 0.25 for the sun, and 0.75 for the grass.
2. Decimal Race: Write down several decimals with up to 2 decimal places. Have a race with a family member to see who can correctly order the decimals from least to greatest the fastest.
3. Decimal Hunt: Look around your house for items that have prices with decimals. Write down the prices and compare them using place value.
Talking Points
- "Decimals help us show parts of a whole. Just like how we use fractions, decimals can also represent parts."
- "When comparing decimals, we look at the digits in each place value position to see which is greater or smaller."
- "Remember, the place values in decimals go from largest to smallest: tenths, hundredths, thousandths."
- "If two decimals have the same digit in the tenths place, then we compare the digits in the hundredths place to determine which is bigger."
- "When writing decimals, always remember to include a 0 in the tenths place if there is no whole number. For example, 0.5 instead of just .5."
