CHAPTER 3

Situation of Integration 

• A primary school has two sections, that is, lower primary (P1-P4) and upper primary (P5-P7). The head teacher of the primary school needs to draw a timetable for both sections. The sections should start and end their morning lessons at the same time before break time, start and end their break time at the same time. The after break lessons should start at the same time. The lunchtime for both sections should start at the same time. 

Support: The time to start lessons for the two sections is 8.00am. The duration of the lesson for the lower section is 30 minutes and that of the upper section is 40minutes. 

Resources: Knowledge of fractions, percentages, natural numbers, factors, multiples, lowest common multiples, and the subjects taught in all classes and of time. 

Task: Help the head teacher by drawing the timetable up to lunchtime for the two sections. How many lessons does each section have up to lunchtime? 

Express the total number of lessons for the lower primary as a fraction of the total number of lessons for the whole School. (Consider lessons up to lunch time.)
