LESSON NOTE ON MATHEMATICS FOR PRIMARY 2

TOPIC: NUMBER AND NUMERATION: Whole Numbers 1-20

DURATION: 5 periods (35 Minutes each)

OBJECTIVES: By the end of the lesson the pupils should be able to:

1, count numbers correctly from 1-200;

2, identify and read numbers from 1 – 200;

4, Write 1 to 200.

PREVIOUS KNOWLEDGE: Pupils can count 1-10

TEACHING AID: Concrete objects such as bottle tops, sticks, seeds, small waterproof bags for bundles of seeds/bottle tops, ropes, straws and two hundred square charts etc.
Flash cards and Charts of numbers 1-200 etc.

STEP2:  Introduce new lesson by engaging pupils in a song that has to do with counting. Guides pupils to revise counting of numbers from 1-99 using counters and 100-square charts;

STEP3: Develop lesson by adding one counter to 99 counters, and recap that 100 is equal to 99 plus one i.e. 100 = 99 + 1. Guide pupils to
count numbers 1 to 200. Write 1 to 200 on the chalkboard and count with pupils. Invite pupils to identify some numbers on the chalkboard eg 12, 15, 23, etc

STEP4: Develop lesson further by guiding pupils to use the teaching aid to build up piles in tens and units, and demonstrates that bringing three piles of tens and eight sticks represents 38, etc. Build up piles in tens and units. Guide pupils to use bundles or piles to demonstrate place value. Write numbers 1 to 200 on the chalkboard and guide pupils to write same in their Maths notebook

STEP5: EVALUATION: Evaluate lesson and pupils’ understanding by asking them to:

1, count numbers correctly from 1-200;

2, identify and read numbers from 1 – 200;

3, identify numbers in their order of magnitude

4, Write 1 to 200.
