Thoughts on Reasoning

The following are examples where inductive and deductive reasoning may be used throughout the mathematics curriculum:

M30-1 Trigonometric Identities

Known Identities are used to prove new Identities.

  • Strategies for Proving Trigonometric Identities (Original & KEY)

M30-1 Matching Activity

  • Matching Rational Function Equations with Graphs using a conceptual approach (go to Activity )

 

M20-2 If this is true ... then ...
The premise behind these activities is that students have to look at the true statements that are given and use reasoning to then be able to solve further problems.
M10-C Investigate Negative Exponents
This investigation asks students to explore what happens when exponents become negative.
I usually complete the first chart with the students and then ask them to do the next chart and continue with the questions on the next page.
