Lessons include objectives, formulas, concept development, worked examples, guided and independent practice, differentiated pathways, application, misconception analysis, mastery evidence, reflection, and local completion.
Rational Exponents & Radical Equivalence
Rational exponents unify roots and powers. Exponent properties remain valid when expressions are defined, but even roots require care in the real numbers.

Lesson 02Simplifying Radical Expressions
Simplifying a radical means factoring out perfect powers while preserving absolute-value conditions where required, such as √(x²)=|x|.
Open detailed lesson
Lesson 03Operations with Radicals & Rationalizing
Radical addition requires like radicands after simplification. Multiplication uses distribution, and conjugates rationalize binomial radical denominators.

Lesson 04Solving Radical Equations & Checking Solutions
Powering both sides may introduce extraneous solutions. Every candidate must be substituted into the original radical equation.

Lesson 05Radical Functions, Domains & Transformations
Radical graphs begin at or approach a domain boundary. Transformations determine the endpoint, orientation, and scale, while inverse relationships connect radicals and powers.
Open detailed lesson
Lesson 06Radical Models, Geometry & Measurement Error
Radical models require exact structure, dimensional consistency, and sensitivity awareness because measurement error can be amplified or reduced by roots.
