In pairs, pupils are asked to work on the following sums using their preferred method 56 + 75 =
| Pupils pay attention and participate |
STEP 3 CLASS-WORK | 1. Use column method and simplified pictorials to solve the following a. 39 + 84 = b. 58 + 77 = c. 94 + 48 =
| Pupils attempt their class work |
STEP 4 HOME-WORK | 1. Use column method and simplified pictorials to solve the following a. 86 + 65 = b. 67 + 96 = | Pupils attempt their class work |
STEP 5 SUMMARY | The teacher summarizes reminding the pupils of the steps in carrying out addition using the simplified pictorial and the column method
She marks their class works, makes corrections where necessary and commends them positively |

PERIOD 2: Addition
PRESENTATION | TEACHER’S ACTIVITY | PUPIL’S ACTIVITY |
STEP 1 ORAL ASSESSMENTS | The teacher asks questions on mental maths with 2-digit numbers treated so far | Pupils respond and participate |
STEP 2 DISCUSSION | The teacher discusses all the methods used by some learners in the oral assessments(some of the questions are solved on the board by the learners) and addresses any misconceptions that may have risen | Pupils pay attention and participate |
STEP 3 WRITTEN ASSESSMENTS | 1 Solve the following using simplified pictorial a. 65 + 52 = b. 54 + 85 = c. 39 + 94 = d. 86 + 98 = e. 58 + 59 =
2. Solve the following using the column method a. 53 + 64= b. 81 + 73 = c. 85 + 89 = d. 57 + 86 = e. 74 + 48 =
| Pupils attempt their class work |
STEP 4 SUMMARY | The teacher marks the written assessments, corrects were necessary and commends the pupils |

PERIOD 3: Subtraction using column method
PRESENTATION | TEACHER’S ACTIVITY | PUPIL’S ACTIVITY | ||||||||||||||||||||||||
STEP 1 MENTAL MATHS | The teacher begins the lesson with some mental calculations Calculate 1. 13 - 5 = 2. 16 - 9 = 3. 15 - 9 = 4. 11 - 6= 5. 12 - 8= 6. 12 - 7 = 7. 16 - 7 = 8. 12 - 9 = 9. 12 - 6 = 10. 11 - 9 = | Pupils respond and participate | ||||||||||||||||||||||||
STEP 2 CONCEPT DEVELOPMENT | The teacher writes 138 -53 = _____ on the board. The pupils are asked to solve the question using the simplified pictorial(hundreds, tens and ones should be crossed out using double lines and make sure arrows are drawn to signify borrowing)
She further uses the column method to subtract the same example
O: 8-3 = 5 T: 130-50=80 | Pupils pay attention and participate | ||||||||||||||||||||||||
STEP 3 CLASS-WORK | Solve the following using the column method a. 159 – 64 = b. 128 – 41 = c. 136 – 82 = d. 167 = 73 = e. 119 – 36 = | Pupils attempt their class work | ||||||||||||||||||||||||
STEP 4 HOME-WORK | Solve the following using the column method a. 155 – 92 = b. 139 – 45 = c. 147 - 74 = | The pupils writes it in their homework book | ||||||||||||||||||||||||
STEP 5 SUMMARY | The teacher reminds the pupils how simple subtraction problems were solved using pictorials and column method
She marks the class work, make corrections where necessary and commends the pupils positively

ASSESSMENT
1 Solve the following using simplified pictorials:
a 81 + 76 = (157)
b 42 + 89 = (131)
c 175 – 82 = (93)
d 142 – 65 = (77)
2 Solve the following using the column method:
a 56 + 75 = (131)
b 99 + 99 = (198)
c 113 – 48 = (65)
d 162 – 88 = (74)
