Comparing Fractions: Tell Them How You Know!
Students will be able to read, write, and compare decimals to thousandths with a partner.
- Have your students turn and tell a neighbour three things that are more fun to do with a partner. Circulate the room to listen in on student shares.
- Allow students to share an idea they either heard or had themselves.
- Tell your class that like all the great ideas that were shared, comparing fractions is also more fun when you read, say, and compare them with a partner!
Explicit Instruction/Teacher modeling(10 minutes)
- Hand out the Read, Compare, Tell: Decimal Comparisons worksheet and lead your students through the introductory example.
Guided practise(10 minutes)
- Have a pair of students perform the first example exercise on the Read, Compare, Tell: Decimal Comparisons worksheet and answer any clarifying questions.
Independent working time(15 minutes)
- Assign the remaining exercises to your students.
- Pair students in trios for added peer support.
- Before releasing students to complete their exercises, practise identifying the proper digits to look at when comparing decimals to the thousandths place.
- A sentence frame you can use would be: “I begin to compare decimals to the thousandths place by first looking at the //Digit. If necessary, I move to the //Digit.” Do this until there are two different digits to compare.
- For extra challenge have students compare numbers to the thousands that extend to the thousandths place.
- Taking photographs of real-time solutions and uploading them into online documents for classroom discussion is a great resource for teachable moments.
- Show your students a pair of numbers to compare like: 6.782 and 6.779.
- Have students explain the comparison.
- Then ask students to explain which digits could be switched in 6.779, to make it greater than 6.782.
Review and closing(10 minutes)
- Review answers and explanations with your students.
- Discuss: What’s more important when comparing two numbers, the size of the digit or the place value?
