Learning Goals
Students will be able to identify rational and irrational numbers from decimal forms, place them on a number line, and estimate square roots and cube roots using benchmark values and rational approximations.
Students will be able to compare and justify equivalent exponent expressions using power rules, patterns, and checks for accuracy.
Students will be able to convert, represent, and compare real-world quantities in scientific notation using measurement and data contexts.

Investigation Notebook: Number, Root, and Scientific Notation Evidence Record
Students complete a research-style notebook showing their question refinement, worked examples, number line placements, exponent checks, root estimates, and scientific notation conversions. The notebook must include raw work, annotations, and a brief personal analysis of when exact values or estimates are appropriate.
Measurement Mystery Investigation Report and Mini-Presentation
Small groups synthesize their clues, data logs, visual models, and conclusions into a formal report and short presentation. The team product must show shared findings, note disagreements or anomalies, and explain the method they used to decide between exact and approximate values.
