Mastering Fraction Reduction Techniques

Mr. Lincoln guides sixth-grade students through reducing fractions to their simplest terms. The lesson covers key vocabulary such as numerator and denominator, explains the concept of simplest terms, and provides a step-by-step example of finding the greatest common factor (GCF) to reduce fractions. Students are instructed to practice the process and check their work with the teacher.

What is the top number of a fraction called?

• Denominator

• Quotient

• 2

• 3

• 9

• 1

What is the simplified form of the fraction 9/18?

• 4/5

• 1/2

• 2/3

What should you do after finding the GCF of the numerator and denominator?

• Divide the numerator and denominator by the GCF

• Multiply the numerator and denominator by the GCF

• Add the GCF to the numerator and denominator

• Subtract the GCF from the numerator and denominator

What should you do after completing each practice problem?

• Erase your work and start over

• Check with your teacher for a stamp or check mark
