Graph Investigators

A 10-day instructional unit on rigid transformations and congruence mapping for 8th-grade mathematics, aligned with NC Math Standard 8.G.2. The sequence covers translations, reflections, and rotations, emphasizing coordinate rules, properties verification using patty paper, and composition of transformations to define and prove congruence.

A 45-minute 7th-grade math lesson focusing on multiplying and dividing integers and applying the order of operations. Through a courtroom-themed narrative, students resolve mathematical 'disputes' using real-world modeling and guided peer collaboration.

A student-facing practice worksheet with guided scaffolds for multiplying, dividing, and evaluating multi-step integer expressions. Includes name/date fields, visual reference blocks, and progressive practice from basic rules to complex multi-step "verdicts".

A curriculum unit tracing the development of linear equations. Students journey from ancient informal heuristics (False Position) to modern symbolic algebraic equations.

Students demonstrate mastery of rigid transformations, property preservation, congruence proofs, and transformation sequences under NC Math Standard 8.G.2 via a 15-question, high-DOK unit assessment.

A student-facing classroom matching activity pairing real-world legal and financial scenarios to integer expressions and simplified mathematical solutions. Includes workspace for written justifications.

A summer-long math intervention bypassing rote memorization of multiplication to build intuitive pre-algebraic thinking using visual grids, helper facts, and balance puzzles.

Students learn how to apply multiple transformations in sequence (e.g., reflect, then translate) and track coordinate changes step-by-step.

A 16:9 presentation designed for direct instruction on multiplying and dividing integers and PEMDAS/Order of Operations. Features courtroom analogies, sample 'disputes' (problems), and visual rules.

Un ensemble de cartes mentales et d'infographies pédagogiques pour guider les élèves de collège (4ème, 3ème) dès la rentrée.

In this lesson, students explore translations using coordinate grids and patty paper. They verify that translations preserve segment lengths, angle measures, and parallel lines, and write coordinate rules (x+a, y+b).

A comprehensive 45-minute lesson plan for teachers, detailing pacing, instructional strategies, common misconceptions, exit ticket reviews, and differentiated guidance for teaching integer operations.
