Arithmetic.—1. Bills of household supplies, such as furniture, fuel, meat, groceries, bed and table linen, material for clothing. This will teach the current prices as well as the usual quantities purchased.
2. Making out the daily, weekly, or monthly supply and cost of any one item of food, being given the number in the family and the amount used by each per day.
Example: One loaf costs 6c. and cuts into 18 slices. Find the cost of bread for two days for a family of six, if each person uses 1-1/2 slices at one meal.
3. Making out the total weekly or monthly expenses of a household, given the items of meat, groceries, fuel, gas, etc. This brings up the question of the cost of living.
4. Making out the total cost of a cake, a loaf of bread, a jar of fruit, or a number of sandwiches, given the cost of the main materials and fuel used. Compare the home cost with the cost at a store. This may be used to teach economy.
Geography.—1. The sources of our water supply.
2. The geographical sources of our ordinary household materials, their shipping centres, the routes by which they reach us, and the means of transportation.
Examples: Fuels, common minerals used in building and furnishing; timber for floors and furniture; manufactured goods, such as cotton, linen, carpets, china; domestic and foreign fruits; common groceries, such as salt, sugar, tea, coffee, cocoa, spices, rice, cereals, and flour.
