| Indicator (code): B5.1.1.3.4-5 Recognize relationship between factors and, multiples of whole numbers from 1 to 100 | Content Std (code): B5.1.1.3 Demonstrate an, understanding of factors, multiples of, numbers including composite, even,, odd and prime numbers from 1 to 100 |

| T.L.R.(s): bottle tops, locally made number cards, exercise books | Keywords: Numbers, Number, Factors |
Phase 1: Starterpreparing the brain for learning Review learners understanding in the previous lesson using questions and answers Engage learners to play games and sing songs to begin the lesson.
Let learners solve this Using only addition, how can you use eight eights to get the number 1000? Answer: 888+88+8+8+8
Draw a 6 by 6 multiplication chart and use it as a game board to play the 3-in-a-line game with a pair of dice or playing cards.
Players take turns in throwing a one dice and mark (or cover) a number that can be divided by the results (i.e. a quotient). The winner is the one who obtains three numbers in a line.
Have learners to solve the following within a given duration. Complete with “>”, “<” and “=” 45 67 475 457 17 71 4+5 6+7 4+3 3+4 45-10 70-9 Teacher calls out numbers from 1 to 20
Have learners to write number patterns in the air. Randomly call learners to write a said number on the board | Phase 2: Mainnew learning including assessment Have learners use factor tree method to determine prime factors of any given whole number. For example the prime factors of 24 For instance, from the figure 24 = 2×2×2×3 so 2 and 3 are the prime factors of 24.
Ask learners to list the factors of two or more given whole numbers using the factor tree; for 36 and 48 we have 36= 2×3×2×3=2×2×3×3 and 48= 2×3×2×2×2=2×2×2×2×3.
Guide learners use the prime factorization to determine the HCF by underlining the common factors in each product 36=2×2×3×3 48= 2×2×2×2×3 → which is 2×2×3=12;
Have learners use the prime factorization by inspection to determine the LCM by underlining the largest number of factors in each Product 36=2×2×3×3 48= 2×2×2×2×3 → which is 2×2×2×2×3×3=144 Learners place factors in a Venn diagrams to find the HCF and LCM of 36 and 48. i.e. the HCF is product of factors in both circles →2×2×3=12; and the LCM is product of factors in the diagram →3×2×2×3×2×2 =144
Learners use the prime factorization to determine the LCM and HCF of three numbers using (i) prime factorization using table and dividing through by prime factors. Example 1, find the LCM and HCF these sets of numbers: 12, 20 and 30. (see method in figure), i.e. HCF = 2, and LCM = 2×2×3×5 = 60.
Investigate even and odd numbers. How do you know a number is even or odd?
Engage learners to play the sharing game to demonstrate even and odd numbers.
First, give two oranges to two learners to share equally. With this, learners get one each. Let learners record the number 2 down in their books,
Again, give three oranges to two learners to share equally. Learners realize that it cannot shared equally since there will be reminder of one. Let learners record the number 3 down in their books.
Continue with several examples for learners to list the numbers that are divisible by 2 and those which are not. Example: {2,4,6,8,10,12,14,16...} {3,5,7,9,11,13,15,17,19...}
Investigate numbers that are multiples of 4 and 6. How do you know a number is a multiple of 4? a multiple of 6? (This is also known as the divisibility test). Investigate perfect numbers, that is, numbers whose factors add up to the Number; for instance 6 has factors 1, 2, 3 and 6. The sum of factors other than 6 is 1+2+3 =6, and hence 6 is a perfect number. How many more perfect number can we find in the first 100 whole numbers? For this activity, learners use bottle tops, locally made number cards and exercise books to make arrays or sequences, identify the rule or factors and record their findings. | Phase 3plenary / reflections Ask learners to tell you what they have learnt and what they will like to learn in the next lesson
Give learners individual or home task. Use the factor tree to determine the prime factors for the following. i. 32 iv. 30 ii. 50 v. 120 iii. 48 vi. 24
Give learners individual or home task.
Give learners individual or home task. 1. list prime numbers between 10 and 50
2. find the following A={odd numbers between 1 and 10} B={prime numbers between 2 to 20}
Ask learners to tell you what they have learnt and what they will like to learn in the next lesson |
