This lesson introduces 9th-grade students to the concept of slope, enabling them to calculate it from graphs or two given points and interpret it as a rate of change in real-world scenarios.
A foundational lesson on solving one-step algebraic equations using inverse operations. Includes a visual reference guide and a structured practice worksheet with mixed operations.
A lesson on solving systems of linear equations using the substitution method (equal values method). Students learn to merge two identities (equations) for the same variable to find the coordinates of the "Double Agent" (intersection point).
A 30-minute introductory lesson on algebraic substitution. Students learn to verify if a given value is a solution to an equation by substituting the variable with the number and checking for equality.
A fundamental introduction to solving one-step equations using inverse operations with whole numbers. Students will practice addition, subtraction, multiplication, and division equations.
A hands-on lesson focusing on the recognition and application of mathematical symbols in numbers and operations through a collaborative Tarsia puzzle activity.
A comprehensive lesson on supplementary and complementary angles, focusing on definitions, identification, and calculating unknown values in geometric diagrams.
A comprehensive lesson covering the seven fundamental properties of parallelograms, based on the instructional video by Mr. Dallas. Students will learn definitions, congruence, supplementary angles, and diagonal relationships.
A foundational lesson on solving one-step algebraic equations using inverse operations, featuring a comprehensive reference guide and practice opportunities.
A comprehensive lesson on graphing linear equations using the slope-intercept form ($y = mx + b$). Students will learn to identify key components of the equation and translate them into visual lines on a coordinate plane.
A 15-25 minute exploration into how ancient navigators used fixed points (the North Star) and the repeating patterns of the universe (microcosms, macrocosms, and symmetry) to navigate without modern technology.
A 15-30 minute exploration of how ancient Phoenicians used the macrocosm of the stars to navigate the microcosm of their ships, featuring the root words micro/macro/cosmos and the mathematics of rotational symmetry.
