This problem solving activity has a measurement focus.
PSTV is planning to show wildlife films in the time slot between 1 o'clock and 5 o'clock on Thursdays.
If each programme lasts half an hour, how many different programmes will they need to buy to fill the time slot?
This problem helps explore the idea of half-hours. This is both an important concept in time and a useful application of the simple fraction one-half.

How many programmes would PSTV need from 11 o'clock in the morning until 6 o'clock in the evening?
This might be done with rods or by using a clock face. It might also be another chance to practice counting in 2s.
There are four hours to fill in. Each hour has two half-hour programmes. So PSTV needs 2 + 2 + 2 + 2 equals 8 programmes. Any combination of 8 films could be used to solve this problem.
This can be proven using the same methods that were used to prove the solution to the original problem. There are seven hours to fill in between 11 o'clock in the morning until 6 o'clock in the evening. Each hour has two half-hour programmes. So PSTV needs 2 + 2 + 2 + 2 + 2 + 2 + 2 equals 14 programmes. Any combination of 14 films could be used to solve this problem.
