Writing Fraction Comparison Sentences
Writing Fraction Comparison Sentences is a Grade 3 math skill from Eureka Math teaching students to express fraction comparisons using the symbols >, <, and =. After comparing two fractions (using visual models, number lines, or comparison rules), students write a formal comparison sentence with the correct symbol between them. For example: 3/4 > 2/4, or 1/3 = 2/6. This skill builds precision in mathematical language and connects visual or logical fraction comparison to written symbolic notation used throughout mathematics.
Key Concepts
To express the comparison between two fractions, we use the symbols for greater than ($ $), less than ($<$), and equal to ($=$). The comparison symbol is placed between the two fractions to create a true number sentence.
Common Questions
What symbols are used to write fraction comparison sentences?
Greater than (>), less than (<), and equal to (=). Place the correct symbol between the two fractions to form a true comparison sentence.
How do you write a comparison sentence for 2/5 and 3/5?
Compare: both have denominator 5, so compare numerators. 2 < 3, so 2/5 < 3/5. Write: 2/5 < 3/5.
How do you remember which way the comparison symbol points?
The open (wide) end of the symbol always faces the larger number. The pointed end points to the smaller number. For 3 > 1, the wide end faces 3.
Write a comparison sentence for 1/4 and 1/2.
1/4 < 1/2. Fourths are smaller parts than halves, so 1/4 is a smaller amount than 1/2.
In which textbook is Writing Fraction Comparison Sentences taught?
This skill is taught in Eureka Math, Grade 3.
