Multiplication & Division Fact Families
Visual fact triangles, inverse relationships, distributive property, and long division algorithms.
DMSB: Divide, Multiply, Subtract, Bring down • a × b = c ↔ c ÷ a = bFractions, Decimals & Percentages
Benchmark conversion tables, common denominators, and reciprocal division (Keep-Change-Flip).
KCF: Keep, Change, Flip • 1/2 = 0.5 = 50% • 1/4 = 0.25 = 25% • 3/4 = 0.75 = 75%Algebra Basics: Solving for X
Systematic multi-step equation solving, balance principle, distributive property, and verification.
Golden Rule: Whatever operation you perform on one side, you must mirror on the other.Geometry Essentials & Formula Sheet
Area, perimeter, surface area, cylinder/cone volume, and the Pythagorean Theorem.
Right Triangles: a² + b² = c² • Circle: A = πr², C = 2πr • Cylinder: V = πr²hReading Comprehension & Critical Analysis
Main idea vs topic, context clues (IDEAS), author's purpose (PIE), and inference formulation.
Inference Formula: Text Clues + Prior Schema = Valid Logical DeductionEssay Writing: The PEEL Blueprint
Introductory thesis statements, body paragraph PEEL scaffold, and synthesis conclusions.
P: Point • E: Evidence • E: Explanation (Analysis) • L: Link back to thesisEarth Science: Rocks, Water & Weather
The rock cycle triad, hydrologic cycle phases, atmospheric layers, and weather front mechanics.
Igneous (Melted) ↔ Sedimentary (Compacted) ↔ Metamorphic (Heated & Pressured)Life Science: Cells & Living Systems
