Students negotiated basic equations in their heads to start the class off. For instance, a student refuses to reveal his or her age but does say that in 10 years they will be 22 years old. We agreed to formally represent the student's age with the variable x and to write the equation:
x + 10 = 22
This was the starting point for investigating how to solve equations involving only addition and subtraction and students were advised to follow three principles:
1. Isolate the variable
2. Use 'opposite' operations
3. Balance the equation
Tonight's home nugget is a chance to put these principles into practice:
