I can understand how maths is used by agricultural workers (animals).
Lesson details
Key learning points
- There are multiple factors to consider when rearing livestock
- One factor is the amount of land each cow would need
- Calculations are needed to work out the milk yield per cow and the cost of care
Keywords
Area - The area is the size of the surface and states the number of unit squares needed to completely cover that surface.
Percentage loss - Percentage loss is the decrease when referencing something that loses cost/mass/length, etc. given as a percentage of the original amount.
Common misconception
The factors mentioned in the lesson are the only factors to consider when considering costs/profits of livestock.
There are many more factors to consider. Pupils could research these or brainstorm with a partner. An example could be selling the wool from any sheep owned.
