MARASIGAN EdD Principal IV Tuesday I. CURRICULUM CONTENT, STANDARDS, AND LESSON COMPETENCIES A. Content Standards The learners have knowledge and understanding of simple patterns and number sentences . B. Performance Standards By the end of the quarter, the learners are able to generate a simple pattern and describe the rule used. (NA) C. Learning Competencies The learners will be able to: complete a number sentence: a. to represent a property of operations (e.g., 4 + 3 = 3 + __) (commutative property of addition) b. to represent equivalent number facts (e.g., 4 + __ = 6 + 3) D. Learning Objectives At the end of the lesson, the learners will able to complete a number sentence: a. to represent a property of operations (e.g., 4 + 3 = 3 + __) (commutative property of addition) b. to represent equivalent number facts (e.g., 4 + __ = 6 + 3) .

Review A.Activating Prior Knowledge Find the answer to each question. 1) 9 − 4 + 3 x 8 = ______ 2) 5 x 5 − 3 x 2 = ______ 3) 6 x 5 + 6 + 4 = ______ 4) 8 x 5 + 10 − 12 = ______ 5) 6 x 4 + 10 − 3 = ______ 1.Lesson Purpose What does MDAS mean? Equivalent number facts refer to number sentences that yield identical numerical outcomes or results when computed despite variations in the arrangement or composition of numbers and operations. B. Establishing Lesson Purpose Example 1. 2+ 3 = 5 and 1 + 4 = 5, thus 2 + 3 = 1 + 4. 2. Unlocking Content Vocabulary Pattern is defined as a sequence of repeating objects, shapes, or numbers. A pattern has a rule that tells us which objects belong to the pattern and which objects do not belong to the pattern. Number sentences are a combination of numbers and mathematical operations. C. Developing and Deepening Understanding 1. Explicitation Giving more examples Example 1. Determine the value of N in the number sentence. 8 + 12 = N × 4 Solution. 8 + 12 = N × 4 20 = N × 4 To get the missing factor: 20 ÷ 4 = N Answer: 20 ÷ 4 = 5, therefore N = 5. Example 2. Determine the value of N in the number sentence. 64 - 8 = 25 + N Solution. 64 - 8 = 25 + N 56 = 25 + N To get the missing addend: 56 - 25 = N Answer: 56 - 25 = 31, therefore N = 31. Which part is difficult to answer? Why? What should be remembered in performing varied operations? 2.Worked Example Address: Barangay A, Rosario, 4225 Batangas (043)312-5563 / 09089898942 107571@deped.gov. Match the number sentence in Column A with the correct value of N in Column B. Column A 1. 2 x N + 3 = 17 2. (N - 5) x 4 = 16 3. 18 / (N + 1) = 3 4. 3 x N - 7 = 11 5. (N + 2) / 3 = 4 6. 4 x (N - 2) = 20 7. 24 ÷ N + 5 = 11 8. 5 x N - 12 = 23 9. (N / 2) + 6 = 10 10. 3 x (N + 1) - 5 = 19 Column B A. N = 12 B. N = 7 C. N = 4 D. N = 8 E. N = 6 F. N = 5 G. N = 9 H. N = 11 I. N = 3 J. N = 2 3.Lesson Activity The pupils will work in groups. Translate the word problems into number sentences and solve for N. 1. "Sarah had N apples. She gave 3 to her friend and had 7 left. How many apples did Sarah have originally?" 2. "John earned PhP5 for each hour he worked. He worked N hours and earned PhP30. How many hours did he work?" 3. D. Making Generalizations "A box contains N candies. If you divide them equally among 4 friends, each friend gets 6 candies. How many candies were in the box?" 1.
