1. Topic-
|
| Comparing Fractions Using Fraction Strips |
| |
|
2. Content-
|
Fractions with common denominators
-numerator
-denominator |
| |
|
3. Goals: Aims/Outcomes-
|
If two fractions have the same denominator, the fraction with the
greater numerator is the greater fraction.
|
| |
|
|
4. Objectives-
|
Students will use models and qualitative reasoning to compare fractions
with the same denominator.
|
| |
|
5. Materials and Aids-
|
Fraction Strips
White Boards
Markers
Dice |
| |
|
6. Procedures/Methods-
|
|
A. Introduction-
| You already know who to compare whole numbers. Today, you will learn
how to compare pairs of fractions with the same denominator. |
| |
|
|
B. Development-
1. What is the number on top called - numerator.
2. What is the number on bottom called - denominator.
3. How are the fractions 2/6 and 4/6 similar? How are they different?
- Draw fractions on white board.
- Students - They are similar because they have the same denominator.
They are different because they have different numerators.
- Teacher - Which fraction is greater?
- Students - 4/6 is greater because there is more of it shaded in.

C. Practice-
1. Write these number sentences on the board:
5/8 < or > 7/8
4/6 < or > 1/6
3/4 < or > 1/4
Students will shade in fraction strips for each number sentence and
then share their reasoning to a partner.
2. Students can compare fractions by comparing the numerators.

|
|
D. Independent Practice-
1. Have students work with fraction strips to compare the fractions
and complete the number sentences:
1/2 < or > 2/2
2/3 < or > 1/3
1/8 <, >, or = 1/8
2. Assign each pair a denominator.
3. Students will take turns rolling the dice to find the numerator
to compare fractions.
4. Students must draw their fraction strips, write their number sentence,
and say their number sentence before rolling the dice to compare a
new set of fractions. |

E. Accommodations (Differentiated Instruction)-
1. Students use manipulatives.
2. Give positive reinforcements every few minutes.
3. Have students think-pair-share their reasoning. |
| |
|
|
F. Checking for understanding-
1. Students must say their number sentence, write their fraction
comparisons, and draw and visual representation.
2. Quick check at end of lesson.
3. Topic Test |
| |
|
|
G. Closure-
Students create their own fraction comparison using the same denominator.
