PERIOD 1: Addition using various strategies
PRESENTATION  TEACHER’S ACTIVITY  PUPIL’S ACTIVITY 
STEP 1 MENTAL MATHS  The teacher begins the lesson with some mental calculations Calculate 1. 8 + _____ = 10 2. 37 + ___ = 40 3. 84 + _____= 90 4. 23 + _____ = 30 5. 51 + ______= 60 6. 75 +_____ = 80 7. 16 + _____ = 20 8. 42 + _____ = 50 9. 69 + _____ = 70 10. 95 + ______ =  Pupils respond and participate 
STEP 2 CONCEPT DEVELOPMENT  The teacher writes 98 + 34 = _____ on the board. Learners are encouraged to use any of the taught strategies to answer the questions
In pairs, pupils are asked to work on the following sums using their preferred method 56 + 75 =
 Pupils pay attention and participate 
STEP 3 CLASSWORK  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 HOMEWORK  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 2digit 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) So 135 58 = 85 She further uses the column method to subtract the same example
O: 83 = 5 T: 13050=80  Pupils pay attention and participate  
STEP 3 CLASSWORK  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 HOMEWORK  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


PERIOD 4: 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 – 8 = 2. 16 – 7 = 3. 15 – 6 = 4. 18 – 9 = 5. 17 – 9 = 6. 16 – 8 = 7. 15 – 7 = 8. 12 – 3 = 9. 14 – 7 = 10. 11 – 4 =  Pupils respond and participate 
STEP 2 CONCEPT DEVELOPMENT  The teacher writes 136 – 49 on the board and asks the learners to solve the question using simplified pictorials
 Pupils pay attention and participate 
STEP 3 CLASSWORK  Solve the following using column method and simplified pictorials a. 114  28 = b. 144 – 67 = c. 123  98= d. 167  79 = e. 131  64=  Pupils attempt their class work 
STEP 4 HOMEWORK  Solve the following using column method and simplified pictorials a. 112 – 38 = b. 131 – 95 c. 184 – 87 =
 The pupils writes it in their homework book 
STEP 5 SUMMARY  The teacher reminding 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


PERIOD 5: Weekly Test/consolidations
TEACHER’S ACTIVITY: The teacher revises all the concepts treated from period 14 and gives the pupils follow through exercises, quiz and tests . She marks the exercises, makes corrections and commends the pupils positively.
