Discussing new concepts and practicing new skills no.1.( Modeling) Sample Problem: Teacher Clea has to split her class of 36 pupils into different groups with equal numbers of members. In how many ways can she group her pupils without excess? There are two types of To answer the problem word problems you may above, we can apply encounter. It could be: the Polya’s technique in solving word problem: ❖ Routine problems Using POLYA’S four-step that are useful for daily plan a. living; or ❖ Non-routine problems which are mostly concerned with developing mathematical reasoning and fostering an understanding that mathematics is a creative endeavor. A.Understand: ➢ Know what is asked The common number of trees in each row ➢ Know what are given 50 seedlings of boys 30 seedlings of girls B. Plan: ➢ Determine the operation/method/proc edure to be used Find the common factors by factor tree method c. Solve: ➢ Use any method to solve the problem Find the common factors of 50 and 30 E. Discussing new concepts and practicing new skills no.2( Guided Practice) By looking at the digits of a large number or by doing simple calculations, you can easily tell whether a number is a factor of a given number or not. Remember that a number is divisible by: ➢ 2 – if it is even and ends in 0, 2, 4, 6, or 8 Example: 106 is divisible by 2 because it ends in 6. Example Example Example ➢ 4 – if the number formed by its last two digits is divisible by 4. Example: 612 is divisible by 4 because the number formed by its last two digits are 12, which is divisible by 4. ➢ 8 – if the number formed by its last three digits is divisible by 8. Example: 913 824 is divisible by 8, because the number formed by its last three digits is 824, which is divisible by 8. ➢ 5 – if its ones digit is either 0 or 5 Example: 487 580 is divisible by 5 because it ends in 0. ➢ 9 – if the sum of its digits is divisible by 9. Example: 9 684 is divisible by 9 because the sum of all its digits is 9 + 6 + 8 + 4 = 27, and 27 is divisible by 9. ➢ 11 – if the difference of the sum of the odd-positioned digits (starting from the left) and the sum of the even-positioned digits (starting from the left) is zero or if it is a multiple of eleven. Examples: 2 376 is divisible by 11, because (2 + 7) – (3 + 6) = 0. 76 813 is divisible by 11, because (7 + 8 + 3) – (6 + 1) = 11, which is a multiple of 11. ➢ 6 – if it is divisible by 2 and 3 Example: 5 652 is ➢ 3 – if the sum of even. The sum of its the digits of the digits is 5 + 6 + 5 + 2 = number is divisible by 18, which is divisible by 3 Example: 315 is 3. So, 5 652 is divisible by divisible by 3 6 because it is divisible because 3 + 1 + 5 = 9 by both 2 and 3. and 9 is divisible by 3. ➢ 10 – if its ones digit is zero Example: 850 is divisible by 10 because 850 ends in 0. ➢ 12 – if the sum of its digits is divisible by 3 and the number formed by its last two digits is divisible by 4. Example: 324 is divisible by 12 because the sum of all its digits is 3 + 2 + 4 = 9, which is divisible by 3. Also, the number formed by its last two digits is 24, which is divisible by 4. F. Developing Mastery (Leads to Formative Assessment 3.) ( Independent Practice ) G. Finding practical application of concepts and skills in daily living (Application/Val uing) Delfin is willing to give a reward to whoever guesses his age this year. His clues state that his age is divisible by 12 and is multiple of 9, and that he is less than 51 years old. How old is Delfin? a. Understand • What is asked? The age of Delfin this year • What are given? Delfin’s age is less than 51, so our range is from 1-50. Listing all numbers divisible by 12 within that range, we have: 12, 24, 36, 48. Another clue is that, his age is a multiple of 9. Among the four numbers, we can eliminate 12, 24, and 48 because the only number that is multiple of 9 is 36. Answer: Therefore, The Barangay Youth Officials of Purok SONA are planning to conduct clean-up drive and tree planting in their costal area. There are 125 youths who are officially registered and are requested to participate the said activity. How many groups could there be with equal number of members in a group? Given: 125 registered Age is divisible by 12 Age is multiple of 9 Age is less than 51 What strategy can we use to solve this problem? Since there are just a few numbers less than 51 which are divisible by 12 and 9, we will use Listing Method and Elimination. Delfin’s age is 36 youth Asked: number of group and equal number in each group. Solution: 125 is divisible by what number? By 2, 3, 4, 5,6, 8, 9 and 10? By 2: even and number ending in 0, 2, 4, 6, or 8 ➢ 125 is not divisible by 2. By 3: if the sum of the digits is divisible by 3. ➢ 1 + 2 + 5 = 8 is not divisible by 3. H. Making Generalization and abstraction about the lesson( Generalization) Non-routine problems can be done without using a standard procedure. They can be solved by drawing a picture, using a I. Evaluating learning number line, actingout, making a table, and many others.
