Fractions: Numerators and Denominators – Review fraction components – Numerator: parts of the whole – The number above the fraction line – Denominator: total equal parts – The number below the fraction line – Simplifying fractions – Reducing fractions to lowest terms | Begin the lesson by reviewing the basic components of a fraction, ensuring that students can identify and differentiate between the numerator and the denominator. The numerator, located at the top of the fraction, indicates how many parts of the whole are being considered, while the denominator, at the bottom, represents the total number of equal parts that make up the whole. After the review, introduce the concept of simplifying fractions to their lowest terms by finding the greatest common divisor (GCD) of the numerator and the denominator and dividing both by this number. Provide examples and practice problems to reinforce the concept.

Simplifying Fractions Using GCF – Define Greatest Common Factor (GCF) – GCF is the highest number that divides both numbers without a remainder. – Find GCF for numerator & denominator – Use prime factorization or Euclidean algorithm to find GCF. – GCF simplification examples – Example: For 8/12, GCF of 8 and 12 is 4. Simplified form is 2/3. – Practice simplifying fractions | This slide introduces the concept of the Greatest Common Factor (GCF) and its role in simplifying fractions. Begin by defining GCF and explaining that it’s the largest number that can divide both the numerator and denominator without leaving a remainder. Demonstrate finding the GCF through methods like prime factorization or the Euclidean algorithm. Provide examples to show how to use the GCF to simplify fractions to their lowest terms. For instance, with the fraction 8/12, the GCF of 8 and 12 is 4, so dividing both by 4 gives the simplified fraction 2/3. Conclude with practice problems for students to apply their understanding of GCF in simplifying fractions.

Simplifying Fractions: Step-by-Step – Divide by the Greatest Common Factor (GCF) – Find GCF of numerator & denominator, then divide both by it – Check if further simplification is possible – After dividing, see if the fraction can be reduced more – Practice with a class example – Example: Simplify 16/24 together | Begin by explaining the concept of the Greatest Common Factor (GCF) and how it is used to simplify fractions. Demonstrate the process of finding the GCF of the numerator and denominator and then dividing both by this number to simplify the fraction.
