STEP 1

MENTAL MATHS

The teacher begins the lesson with some mental calculations

Calculate

1. 1 + 15 =

2. 2 + 25 =

3. 3 + 19 =

4. 4 + 45 =

5. 5 + 78 =

6. 3 + 35 =

7. 1 + 42 =

8. 2 + 55 =

9. 4 + 65 =

10. 4 + 78 =

Pupils respond and participate

STEP 2

CONCEPT

DEVELOPMENT

The teacher writes 348 + 26 = on the board. Learners are asked to solve this using simplified pictorials

A learner is asked to show the solution to the question on the board

Using simplified pictorial

The process is repeated for

59 + 407 =

941 – 22 =

736 – 27 =

Then the teacher writes the following word problem on the board

“There are 129 sweets in the jar. Daniel puts in another 47 sweets. How many sweets are in the jar now?

The teacher then draws the below diagram

The learners are then asked to discuss what the number sentence will be(129 + 47 = ____)

Then the learners are allowed to solve the problem using their preferred method

129 + 47 = 176.

The teacher explains to the pupils that the word problem is an addition problem since the number of sweets are the ending is more than the number of sweets in the jar at the beginning

The teacher writes the below question on the board

There are 267 children on the field. 39 go back to their classrooms. How many children are on the field now?

The teacher draws the below diagram on the board

The teacher asks the learners to think what the number sentence will be(267 – 39 = _____)

The learners are then asked to work out the solution

267 – 39 = 228

Pupils pay attention and participate

STEP 3

CLASS-WORK

1. Solve the word problem using bar diagrams

a. The teacher has 342 pencils. The shop down the road gives her 69 more. How many

pencils does she have now?

b Theophilous picks up 543 shells. 29 were broken. How many unbroken shells does Theophilous have?

Pupils attempt their class work

STEP 4

HOME-WORK

1. Solve the word problem using bar diagrams

a. Segun picks up 264 pieces of litter. He then picks up another 17 pieces of litter. How many pieces of litter did Segun pick up altogether?

Pupils attempt their class work

STEP 5

SUMMARY

The teacher summarizes reminding the pupils of the steps in solving word problems using bar diagrams

She marks their class works, makes corrections where necessary and commends them positively

Using simplified pictorial

The same process is repeated for these

1. 673 – 47 =

2. 145 – 136 =

3. 107 - 28 =

Pupils pay attention and participate

STEP 3

b. 125 – 46 =

c. 687 – 59 =

d. 574 – 35 =

e. 105 – 58 =

Pupils attempt their class work

STEP 4

HOME-WORK

a. 126 – 89 =

b. 843 – 29 =

Pupils attempt their class work

STEP 5

SUMMARY

The teacher summarizes reminding the pupils of the steps in carrying out subtraction using the column method and how to check whether the solution is correct

She marks their class works, makes corrections where necessary and commends them positively

STEP 1

ORAL

ASSESSMENTS

The teacher asks questions on mental maths with 2 and 3-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 the column method

a. 58 + 59 =

b. 96 + 27 =

c. 156 - 69 =

d. 882 - 65 =

e. 106 – 9 =

2. Check to see if these subtractions are correct by adding them

a. 487 – 28 = 437

b. 262 – 48 = 214
