PRESENTATION

TEACHER’S ACTIVITY

PUPIL’S ACTIVITY

STEP 1

MENTAL MATHS

The teacher begins the lesson with some mental calculations

Count forwards and backwards in multiples of 5 between 5 and 200.

Pupils respond and participate

STEP 2

CONCEPT

DEVELOPMENT

The teacher draws the below flow diagram on the board and explains that the numbers in the blocks on the left are the numbers we will be working with.

The teacher writes the numbers 4, 6, 5, 7, 8 in the rectangles as shown below.

She explains that all of the numbers are going to be subjected to the same rule – multiply by 5.

The teacher asks: What is 4 groups of 5? (20). The answer is recorded in the first output block.

She continues to complete the flow diagram with the learners.

• The teacher asks again: What pattern do you notice? (the rule is that the output numbers are found by

multiplying the input numbers by 5. The output numbers are thus all multiples of 5)

The exercise is repeated using the flow diagram below

CLASS ACTIVITY

The teacher draws the table below.

 5 6 7 8 9 10 x 3

The teacher explains that in the above table we are multiplying by 3 and completes the table with the learners

 5 6 7 8 9 10 x 3 15 18 21 24 27 30

Pupils pay attention and participate

STEP 3

The pattern is _________

Pupils attempt their class work

STEP 4

HOME-WORK

Pupils attempt their class work

STEP 5

SUMMARY

The teacher summarizes by reminding the pupils how to work with flow diagrams and tables to identify number patterns.

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

PERIOD 3: Number patterns, flow diagrams and tables

 PRESENTATION TEACHER’S ACTIVITY PUPIL’S ACTIVITY STEP 1MENTAL MATHS The teacher begins the lesson with some mental calculations Count forwards and backwards in 10s from any multiple of 10 between 10 and 200 Pupils respond and participate STEP 2CONCEPTDEVELOPMENT The teacher then asks the learners what pattern they can see(multiples of 5)CLASS ACTIVITYThe teacher Read the following problem to the learners: Neo collects 4 stickers each week fromShoprite. How many stickers will she have after 6 weeks?The learners are to use any one of both methods to solve the problem. One learner is picked to show the solution on the board Pupils pay attention and participate STEP 3CLASS-WORK 1. Solve the following problem. Show your answers in the table and in the flow diagram. Jenny gets N10 each week. How much will she have after 7 weeks? Pupils attempt their class work STEP 4HOME-WORK Complete the flow diagram Pupils attempt their class work STEP 5SUMMARY The teacher summarizes by reminding the pupils how to work with flow diagrams and tables to solve word problems  She marks their class works, makes corrections where necessary and commends them positively

PERIOD 4: Number patterns

 PRESENTATION TEACHER’S ACTIVITY PUPIL’S ACTIVITY STEP 1ORALASSESSMENTS The teacher asks questions on counting forwards and backwards Pupils respond and participate STEP 2DISCUSSION 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 3WRITTEN ASSESSMENTS 1 Complete the following number lines:a 3s from 240 – 276b 4s from 240 – 276c Which numbers are in both the 3s pattern and the 4s pattern. ____________2 Which numbers between 300 and 400 belongs to both the 25s and the 50s pattern? ______ 3 Extend the pattern:a 485, 490, 495, __, ___, ___, ___b 300, 400, ____, ___, _____, ____, 4 Complete the pattern:a ____, _____, ____, 200, 195, 190b ____, _____, ____, 560, 550, 540c ____, _____, ____, 440, 438, 436d 450, 400, 350, ____, ___, _____, ____ Pupils attempt their class work STEP 4SUMMARY The teacher marks the written assessments, corrects were necessary and commends the pupils

PERIOD 5: Weekly Test/consolidations

TEACHER’S ACTIVITY: The teacher revises all the concepts treated from period 1-4 and gives the pupils follow through exercises, quiz and tests . She marks the exercises, makes corrections and commends the pupils positively.
