Examples, solutions, videos, and lessons to help High School students learn how to
explain each step in solving a simple equation as following from
the equality of numbers asserted at the previous step, starting
from the assumption that the original equation has a solution.
Construct a viable argument to justify a solution method.
Suggested Learning Targets
- Assuming an equation has a solution, construct a convincing
argument that justifies each step in the solution process.
Justifications may include the associative, commutative, and
division properties, combining like terms, multiplication by 1,
etc.
