PERIOD 1: Numbers up to 999

PRESENTATION

TEACHER’S ACTIVITY

PUPIL’S ACTIVITY

STEP 1

MENTAL MATHS

The teacher begins the lesson with some mental calculations

Which is bigger?

1. 34 or 62

2. 71 or 28

3. 36 or 65

4. 43 or 51

5. 99 or 89

6. 19 or 91

7. 16 or 35

8. 56 or 46

9. 45 or 10

10. 55 or 89

Pupils respond and participate

STEP 2

CONCEPT

DEVELOPMENT

The teacher calls out two digit numbers randomly and asks the pupils to call their names(Including numbers whose digits have been reversed and the ones the teen and ten numbers sound familiar)

24, 36

42, 24

19, 90

17, 70

The teacher then displays the container filled with the 321 counters and asks the learners to suggest how the number of counters in the container could be counted. She then explains that for a large number of counters, one by one counting will take such a long time

The teacher then show the pupils the base 10 kit and explains that we could use tens to replace 1 counters and replace 10 tens with a hundred

The teacher then ask the pupils to put all the hundreds to one side, then the tens and then the ones in order to make it easy to see.

The teacher then asks the pupils how many counters were in the container(321). This is seen because we 3 Hundreds, 2 tens and 1 one.

The teacher writes the number symbol 321 on the board and reads the name as Three hundred and twenty one as the learners repeats after her severally.

Pupils pay attention and participate

4. 413

5. 289

The pupils writes it in their homework book

STEP 5

SUMMARY

The teacher summarizes by reminding the pupils that for large counters or items, one by one counting shouldn’t be used rather they should be counted in multiples in this case 10 counters make up one 10, and 10 tens make up 100

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

CONCEPT

DEVELOPMENT

The teacher writes 233 on the board and asks a learner to read it out loud. She repeats this with other 3-digit numbers- 145, 256, 356, 189. 489, 527, 636 etc

The teacher then presents the number 306 on the board using the base 10 kits

She then tells the pupils that the number symbol is 3hundreds, 0 tens and 6 ones

She then draws a place value table and represent the number in it

Hundreds	Tens	Ones
3	0	6

She then further states that the 0 cannot be left out since it will make the number wrong (36)

The same process is repeated for 108, 350, 807, 206, 908

The teacher allows the pupils individually and in pairs represent 3-digit numbers using the base 10 kit

Hundreds	Tens	Ones(Units)
5	9	0

Hundreds	Tens	Ones(Units)
4	3	5

Hundreds	Tens	Ones(Units)
6	9	8

Using the flash cards, the teacher then shows the pupils the expanded form of the numbers on the place value table

Hundreds	Tens	Ones(Units)

167- one hundred and sixty seven

189- one hundred and eighty nine

345- three hundred and forty five

490- four hundred and ninety

678- six hundred and seventy eight

The pupils are asked to match the number symbols to number names and read them correctly repeatedly

CLASS ACTIVITY:

The learners are given a scrap paper.

They are asked to fold it into four blocks tagging each block as count forwards, count backwards, count in 1s and count in 10s.

The learners take turns to select a starting number up to 999

The learner then places a counter on either count forwards or count backwards block

The learner then places a counter on either the count in 1’s or count in 10’s block

The other learner must then count forwards or backwards from the selected starting number in either 1’s or 10’s as determined by the positioning of the counters on the blocks
