One year of access to our comprehensive Geometry teaching videos. These are short, to-the-point instructional videos that cover all essential geometry topics. The course also includes one year of access to the Geometry Solutions Video Library, where every homework and test problem is worked out and explained on video.

The spiral-bound student textbook is consumable, allowing students to easily follow along with lesson videos, take notes, and work problems by hand. This format helps prevent frustrating copying errors and makes reading and handling the material more brain-friendly.

The accompanying spiral-bound solutions manual provides step-by-step solutions for every homework problem, enabling both students and parents to easily and accurately check assignments.

The three-hole punched, loose-leaf test booklet includes two versions of each test (Form A and Form B), allowing students to re-test if needed. The corresponding solutions pages show each test problem worked out in detail. The loose-leaf format allows parents, tutors, or teachers to easily hand out and collect individual test forms and to accurately and quickly check work afterwards.

The three-hold punched, loose-leaf parent guide provides you with all the key information needed to guide your student successfully through Geometry. It includes a pacing guide, grading suggestions, and grade recording sheets.

Denison Geometry is designed for students who may not naturally enjoy math or who simply want a clear, approachable path through geometry. If your student has completed an algebra 1 course (even if they did not fully grasp the content) or they are at a point where they need to begin geometry for credit reasons, this course is a great fit.

If your student has completed a standard algebra 1 course, they are ready to take Denison Geometry. It is not necessary to have mastered every algebra 1 skill before beginning this course, as basic algebra skills are reviewed and reinforced throughout.

Algebra 1 is a necessary prerequisite to geometry because the skills learned in algebra are used throughout the course. While students need to have experience with algebra 1, they do not need to have every skill fully mastered. Denison Geometry provides regular review and reinforcement of key algebra concepts, helping students strengthen their skills and build confidence as they prepare for algebra 2.

Nope! Denison Geometry does not cover formal proof-writing. Throughout the course, students are taught to use the logic, rules, definitions, theorems, and postulates of geometry to work problems, but they will not be asked to write traditional proofs. There are several reasons for this...

1. When writing a proof, there are many "correct" answers. If a proof differs from the answer key, it needs to be closely examined to test its validity. Students often take a different, unexpected, or less direct route to write correct proofs, but rarely discover that their answers are correct when comparing them to an answer key. Instead, they believe their answers are wrong because they don't immediately match the logic of the teacher. This can be very discouraging for students, causing them to dislike geometry or to lose confidence in their math ability
2. Formal proof writing is not used in any future math courses, nor is it tested on standardized tests 
3. During his 25+ years as a math educator, Mr. Denison never saw positive differences in student performance between the years when he did and did not teach proof writing. In fact, proof writing tended to have a negative effect on students, as they almost universally hate writing proofs, which made them dislike geometry and sometimes math altogether

That being said, we're not anti-proof! The skill does have value, but for a typical geometry student (the audience for this course), we've found proof writing to be very counterproductive and therefore chose not to include it in the course.

This course is a full, standard-level program that equips students with every essential geometry skill needed for their next level of study. It is intended for college-bound students (or those who would like to keep that option open). Our Success Geometry course, on the other hand, is a modified course designed specifically for students with learning challenges that make math extremely difficult. You can check out our Success Geometry Course Page or our Success vs Standard Guide for more resources on determining which program is best for your student.

Yes! While algebra 2 could be taken directly after algebra 1, we recommend putting geometry in between the two for several reasons.

For one, algebra 2 is the most difficult of the three courses. By putting geometry before algebra 2, students are given an extra year of growth and maturity before they tackle the more rigorous course. In addition, this order allows students to practice and improve their algebra 1 skills for another year before jumping back into learning new algebraic concepts in algebra 2.

P.S. Mr. Denison actually wrote a blog post on this topic! You can read his thoughts here.

Yep! This course is designed to take a student through an entire geometry course without the need for a tutor or additional instruction.
