Explore the connection between algebraic and graphical representations of relations such as simple quadratics, circles and exponentials using digital technology as appropriate - ACMNA239.
About the Lesson
The number of cans in a stack can be calculated using a relatively simple formula (quadratic), however building the formula using a range of strategies with corresponding visual aids is a much more powerful learning experience. Problem solving strategies such as “breaking the problem down into smaller parts” are employed to help students see how the algebraic expressions are formed. Tackling the problem from different angles helps students understand the different algebraic representations of the same formula.
