Ordering similar fractions
- 1. The University of Mindanao College of Teacher Education Prepared by: Almondia, Jesa O. Audience: Grade 2 (Third Quarter) L.C. arranges similar fractions in increasing or decreasing order (M2NS-111f-78.2). I. OBJECTIVES At the end of the lesson, the pupils are expected to: a. identify similar fractions in increasing and decreasing order, b. demonstrate cooperation in the group activity, and c. order similar fractions in increasing and decreasing orders. II. SUBJECT MATTER Topic: Ordering Similar Fractions Concepts: Similar (like) Fractions are fractions with the same denominators. Increasing orders when numbers are arranged from the smallest to the largest number, while decreasing orders are when numbers are arranged from the largest to the smallest number. Reference: 1.

- 2. 1. The teacher will show examples of fractions and let the students identify the fraction (the numerator or the numbers of part being taken and the denominator or the number of equal parts into which the whole is divided). C. Analysis a. What have you noticed on the fractions? (about their numerators and denominators) b. What have you noticed in their arrangement? D. Abstraction a. The teacher will discuss the concepts behind the given fractions and their arrangement. E. Application (Activity) “Let’s play cards!” a. The students will be group into two and will be given cards, manila paper and masking tape. b. They will make similar fractions from the given cards then, arrange it in increasing and decreasing orders and paste it in the manila paper using the masking tape. c. The first group will arrange their cards in increasing order and the second group will arrange their cards in decreasing order
- 3. d. They will be given 5 minutes to perform the task. e. The group that arranges more similar fractions will be the winner. IV. ASSESSMENT Direction: Order the following similar fractions below in increasing and decreasing orders. 1. 12 15 , 7 15 , 3 15 , 9 15 , 5 15 4. 10 18 , 5 18 , 7 18 , 14 18 , 6 18 Increasing Order: Increasing Order: Decreasing Order: Decreasing Order: 2. 2 20 , 10 20 , 5 20 , 15 20 , 17 20 5. 1 8 , 7 8 , 6 8 , 3 8 , 5 8 Increasing Order: Increasing Order: Decreasing Order: Decreasing order: 3. 7 9 , 2 9 , 4 9 , 1 9 , 8 9 Increasing Order: Decreasing Order: Answers: 1.
