1. Request each pupil to count the number of hens under two years old at his home and also to count the hens that are more than two years old.
2. Request each pupil to find out, if possible, the number of eggs obtained at his home during the whole year.
ARITHMETIC LESSON BASED ON THE CHICKEN CENSUS
1. Using the data collected by the pupils, calculate the total number of chickens under two years old in the district.
Calculate the number over two years old. (The latter are classed as unprofitable.)
2. Using the data obtained by the pupils (provided sufficient data was obtained to make it reasonably reliable), calculate the average number of eggs laid a year by each hen.
3. If the data collected by the pupils as to the number of eggs is thought to be unreliable, make use of the following:
The average number of eggs laid each year by each hen in Ontario is seven dozen. Use this average number, and:
(1) Calculate the value of the eggs produced in this district in a year, the average price of eggs being twenty cents a dozen.
(2) If the average production of eggs were increased to ten dozen (a number that is easily possible under improved management), find the value of the eggs that would be produced in a year, and find the gain that would result from this better management.
