Reviewing Previous Lesson/ Presenting the New Lesson Board Work: Write on the board the commutative property of the following and find the product. 1.) 3 x 4 = _____ 2.) 6 x 2 = _____ 3.) 3 x 5 = _____ 4.) 7 x 4 = _____ 5.) 2 x 8 = _____ PUPIL’S ACTIVITY 1.) 4 x 3 = 12 2.) 2 x 6 = 12 3.) 5 x 3 = 15 4.) 4 x 7 = 28 5.) 8 x 2 = 16 B. Presenting Examples/ Instances of the New Lesson Write the multiplication sentence then answer. 1.) ___________ x ___________ = ____ 1.) 2 x 2 = 4 2.) 2.) 4 x 2 = 8 ___________ x ___________ = ____ 3.) ___________ x ___________ = ____ 3.) 5 X 3 = 15 4.) 4.) 3 x 6 = 18 ___________ x ___________ = ____ 5.) 5.) 7 x 4 = 28 ___________ x ___________ = ____ C. Discussing New Concepts and Practicing New Skills #1 Observe the following groups of objects. 1.) 2 + 2 = _____ How many groups of shells are there? 1.) 2 + 2 = 4 2 groups of 2 The multiplication sentence is 2 x 2 = 4. 2.) 2.) 3 + 3 = 6 3 + 3 = _____ How many groups of pineapples are there? The multiplication sentence is 2 x 3 = 6. 3.) 2 groups of 3 4 + 4 = _____ 3.) 4 + 4 = 8 How many groups of watermelon are there? 2 groups of 4 The multiplication sentence is 2 x 4 = 8. Very good! D. Discussing New Concepts Practicing New Skills #2 and Group Activity: Before proceeding with our activity, what are the things we should consider when we are observing group activity? Group 1: Multiply by 2 2 x 1 = ___ 2 x 6 = ___ 2 x 2 = ___ 2 x = ___ 2 x 3 = ___ 2 x 8 = ___ 2 x 4 = ___ 2 x 9 = ___ 2 x 5 = ___ 2 x 10 = ___ Group 2: Complete the multiplication table of 3. 3 x 1 = ___ 3 x 6 = ___ 3 x 2 = ___ 3 x 7 = ___ 3 x 3 = ___ 3 x 8 = ___ 3 x 4 = ___ 3 x 9 = ___ 3 x 5 = ___ 3 x 10 = ___ Group 3: Complete the multiplication table of 4. 4 x 1 = ___ 4 x 6 = ___ 4 x 2 = ___ 4 x 7 = ___ 4 x 3 = ___ 4 x 8 = ___ 4 x 4 = ___ 4 x 9 = ___ 4 x 5 = ___ 4 x 10 = ___ Very good! E. Developing Mastery (Lead to Formative Assessment 3) Word Problem: It’s Ma’am Melissa’s birthday tomorrow. Her students wanted to surprise her by giving her balloons. If there are 10 students and each of them gives Ma’am Melissa 3 balloons, how many balloons are there all in all? Observe silence Share ideas or cooperate Respect each other members 10 students, Ma’am! How many students are there? 3 balloons, Ma’am! How many balloons each student is planning to give to Ma’am Melissa? 30 balloons, Ma’am! How many balloons are there in all? Show your solution: 3 + 3 + 3 + 3 + 3 +3 + 3 + 3 + 3 + 3 = 30 Using repeated addition: 3 x 10 = 30 Using multiplication: Very good! F. Finding Practical Application Concepts and Skills in Daily Living Find the product. 5 x 5 = ___ 5 x 10 = ___ 5 x 2 = ___ 5 x 8 = ___ 5 x 9 = ___ of 5 x 3 = ___ 5 x 7 = ___ 5 x 6 = ___ 5 x 4 = ___ 5 x 1 = ___ Very good! G. Making Generalizations and Abstractions About the Lesson How do you multiply a number by 2 or The table of 2 follows the pattern of 2, 4, 6, vice versa? What pattern did you 8, 10 at one’s digit place. discover? How do you multiply a number by 3 or The digits in multiples of 3 add up to a vice versa? What pattern did you multiple of 3. (3, 6, 9, 12, 15…) discover? How do you multiply a number by 4 or There is another pattern hidden among the vice versa? What pattern did you multiples of odd and even numbers. All discover? products of 4 are double the products of 2. (4, 8, 12, 16, 20…) How do you multiply a number by 5 or Multiples of 5 have a pattern of 5, 0 in the vice versa? What pattern did you ones place. Every other multiple of 5 is discover? even; every other multiple of 5 is odd. (5, 10, 15, 20, …) How do you multiply a number by 10 or When you multiply any number by 10, you vice versa? What pattern did you simply add a 0 at the end of the number. The discover? multiples of 10 are 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 ... H. Evaluating Learning Complete the multiplication table. 1.) 4 2.) 30 3.) 16 4.) 40 5.) 60 I.
