Keep all of the essential ACT and SAT math formulas in one place with this comprehensive quick-reference guide. This two-page formula sheet includes the most commonly tested concepts in algebra, geometry, coordinate geometry, trigonometry, probability, statistics, sequences, quadratics, exponents, and number properties. Designed for quick review before practice sessions or test day, it helps students reinforce key formulas, recognize important relationships, and build confidence without wasting time searching through notes.

Master the formulas that appear most often on the ACT and SAT with this comprehensive two-page reference guide. Organized by topic, it includes essential concepts from algebra, geometry, coordinate geometry, trigonometry, quadratics, probability, statistics, sequences, exponents, and number properties. Whether you're reviewing before a practice test, completing homework, or preparing for test day, this formula sheet helps you quickly find and apply the mathematical relationships needed to solve problems accurately and efficiently.

50 take-home exams I give every week in my Geometry class to keep the critical algebra skills fresh for my students. Each test consists of 10 problems: finding a coordinate value given two points and a slope of the line, two-step equation, complex multi-step equation, linear graphing (slope intercept, Point Slope form, standard form), finding the slope of two points, reducing fractions, solving quadratics, factoring quadratics, finding the slope of perpendicular lines given an equation in different forms, and solving a system of equations (elimination and substitution are covered)

Engage students in exploring triangle congruence with these 110 diagrams to reinforce their understanding of Side-Side-Side (SSS), Side-Angle-Side (SAS), Angle-Side-Angle (ASA), Angle-Angle-Side (AAS), and Hypotenuse-Leg (HL) criteria. This activity requires knowledge of parallel lines, alternate interior angles, and corresponding angles, reflexive property for specific diagrams, and adding depth to the exploration of congruent triangles. Students will actively apply these concepts, enhancing their proficiency in identifying congruence among triangles.

Diagrams can easily be cut and pasted into your own assessments and quizzes.

MS Word. 6 Full pages of Problems. The document is editable.

40 Proofs in MS Word. Proofs cover SSS, SAS, ASA, ASA, HL, AAS, CPCTC, equidistant theorem, parallel lines, circles, overlapping triangles, and more. All proofs can be easily manipulated to prove other parts of the diagram. I assign one proof every three days to keep the format and structure in my students’ minds.  All proofs are two columns. Proofs range from 6-14 steps.

2026 Update: All diagrams have been professionally updated. Given and Prove can easily be changed in MS Word. The diagrams are static, and parts cannot be manipulated.

Diagrams can easily be copied into your test or preferred layout/format. Given and Proven statements can be copied and manipulated/changed to your preference/style. No Answer key included
