Teaching Textbooks Geometry Version 4.0 Explained with Features and Benefits

Teaching Textbooks Geometry Version 4.0 is a self-paced digital geometry course built for homeschool students, combining animated video lectures, automated grading, and step-by-step problem solutions in a single app. It is the current release of the Geometry course from Teaching Textbooks, a homeschool math company founded in 2004 by brothers Greg and Shawn Sabouri, both former teachers. This article breaks down what the course includes, how it works day to day, what it costs, who it fits best, and how families can confirm a student is ready for it, using information pulled directly from the publisher’s own product page, placement materials, and course description.

What Is Teaching Textbooks Geometry Version 4.0?

Teaching Textbooks Geometry Version 4.0 is the tenth course in the Teaching Textbooks math sequence, which runs from Math 3 through Pre-Calculus and covers grades 3 through 12. The full sequence includes Math 3, Math 4, Math 5, Math 6, Math 7, Pre-Algebra, Algebra 1, Geometry, Algebra 2, and Pre-Calculus, with each level built to cover a full academic year. Geometry Version 4.0 is delivered as an app rather than a printed textbook, and students access it through 12 months of enrollment purchased directly from the company. The course teaches the standard scope of a high school geometry class, including proofs, triangle congruence, angle relationships, area and volume, and coordinate geometry, using video lessons paired with an interactive practice system.

Teaching Textbooks is built as a spiral curriculum, meaning it introduces a topic, moves on to something else, and then circles back to that same topic later at a deeper level. This structure is consistent across every course level the company publishes, not just Geometry, and it is one of the defining traits reviewers point to when describing how the program teaches math over a full school year rather than covering each topic once and moving on permanently.

How Does Teaching Textbooks Geometry Version 4.0 Work?

Each lesson in the course opens with an animated video lecture that walks through a new concept before the student attempts any problems. After the lecture, students work through practice problems on their own, and every single problem includes a step-by-step solution the student can access if they get stuck or answer incorrectly. This watch, practice, and review structure is the same three-step method the company uses across its entire product line, and it is designed so a student can move through a full geometry course without a parent teaching the material directly.

The app also includes hints on many problems, a searchable digital textbook that can be printed or used on screen, and custom wallpapers students can unlock as they progress. Every lesson is graded automatically, and results feed into a running course average that both the student and parent can see at any time. Students can also work out the steps of a problem directly on screen inside the app, which keeps their scratch work in the same place as the lesson itself instead of on separate paper.

What Devices Does the App Run On?

The Version 4.0 app is built to run on computers, tablets, and phones, and it supports offline use for up to six lessons at a time without needing to reconnect to the company’s servers. That offline window makes it usable during travel or in areas with unreliable internet access, which is a meaningful shift from earlier disc-based versions of the curriculum that some longtime homeschool families may remember. Because the app is not tied to a single device, a family can also move a student between a shared computer and a personal tablet without losing progress, as long as the device can connect to sync.

What Features Does Teaching Textbooks Geometry Version 4.0 Include?

The course bundles several tools into one app rather than requiring separate materials for lectures, practice, and grading. The core features include:

• Animated video lecture for every lesson, introducing the concept before practice begins.
• Step-by-step solutions for every problem, not just a subset of practice questions.
• Built-in hints on many problems to guide students without giving away the full answer.
• A full, searchable eBook that mirrors the printed textbook and can be printed by a parent or read on screen.
• Automated grading with a running course average visible to both student and parent.
• A Parent Portal, accessible separately from the student app, where parents can review the gradebook at any time, even after the 12-month enrollment period ends.
• Feature controls for parents, letting them adjust certain settings within the student experience.
• On-screen workspace where students can work out problem steps directly in the app.

Are There Prerequisites?

Yes. Algebra 1 is listed as a prerequisite for the Geometry course, and the company’s own Geometry placement test draws its questions directly from Algebra 1 material and from the geometry chapters covered inside Pre-Algebra. Students also need a physical protractor and a scientific calculator to complete certain lessons, since the app does not substitute for these physical tools. The placement test itself is split into two sections of 15 questions each, is meant to be completed without a calculator, and most students finish in under an hour, according to the company’s published test instructions.

How Do Families Confirm a Student Is Ready for Geometry Version 4.0?

Teaching Textbooks provides free, printable placement tests for every level in its lineup, including Geometry, and the company states these tests apply regardless of whether a family is using the physical product versions or the all-digital app versions. The Geometry placement test is designed to reveal whether a student has retained enough Algebra 1 content to succeed in the course, since geometry proofs and problem-solving lean heavily on algebraic manipulation.

For families unsure which level fits a student, Teaching Textbooks recommends testing at the higher level first. If a student struggles significantly on that higher-level test, the family can then try the next test down to find a better fit. The company also notes that its pass or fail guidelines are intentionally rough, and that a student who scores just under the recommended cutoff on one or two sections is still likely ready for that level rather than needing to drop down a full course.

What Does Teaching Textbooks Geometry Version 4.0 Cost?

A 12-month enrollment for one student costs $79.95, based on current pricing listed on the official Teaching Textbooks website. Enrollment includes a three-month pause feature, which lets families pause the course during scheduled breaks such as summer vacation or holidays without losing access time. Access to the student gradebook through the Parent Portal continues indefinitely, even after the 12-month enrollment window closes, which means parents keep a permanent record of a student’s grades and progress well beyond the active enrollment period.

Families with more than one student can also look into the company’s family discount option, which is listed separately from individual course pricing on the Teaching Textbooks site. The company also sells optional printed textbooks separately for families who want a physical copy of the eBook alongside the app.

Who Is Teaching Textbooks Geometry Version 4.0 Best For?

The course is built specifically for homeschool students, and its structure reflects that. Because the app grades every problem automatically and provides a full video lecture and step-by-step solution for each lesson, it is designed to let a student work through geometry with minimal day-to-day teaching from a parent. That makes it a fit for:

• Homeschool families where the parent is not confident teaching high school geometry directly.
• Independent learners who prefer to work through video lessons at their own pace.
• Families managing multiple students at different grade levels, since each course runs independently and follows its own placement test.
• Students who need to redo problems and see a worked solution immediately rather than waiting for a parent to check their work.

It is worth noting that Teaching Textbooks is not built around Common Core standards. It follows its own independent scope and sequence, which means students transferring in from a different curriculum may need to take the company’s placement test first to find the right starting point, rather than assuming Geometry Version 4.0 lines up lesson for lesson with their previous course.

What Are the Benefits of Teaching Textbooks Geometry Version 4.0?

The most commonly cited benefit is time savings for parents. Because grading is automatic and every lesson includes a full lecture and solution walkthrough, parents are not required to teach geometry concepts themselves or manually check each assignment. The step-by-step solution for every problem also gives students a way to learn from mistakes immediately instead of waiting for feedback, since they can review exactly where their process went wrong on any missed question.

The spiral structure is another benefit reviewers point to consistently. By revisiting concepts multiple times across the course rather than teaching a topic once and moving on permanently, the program is designed to reinforce retention over a full academic year rather than relying on a single pass through the material.

The app-based format of Version 4.0 also removes the need for physical discs, which older versions of Teaching Textbooks used. Running on any modern computer, tablet, or phone, plus supporting offline access for a handful of lessons at a time, makes the course more flexible for families who travel or move between devices during the school year. The permanent gradebook access through the Parent Portal is a practical benefit as well, since it gives families a lasting academic record for transcripts or portfolio purposes long after the 12-month enrollment technically ends.

How Does Geometry Version 4.0 Compare to Earlier Versions?

Teaching Textbooks has released its curriculum in multiple formats over time, moving from printed textbooks with companion CDs to a fully app-based delivery model. Version 4.0 represents the current app-based release, and it is the version currently sold and supported on the company’s website. The company’s placement tests are built to work across both formats, so a family can use the same test to place a student whether they end up using a physical product or the app-based version. Families researching older editions secondhand, such as CD-based versions from previous years, should confirm with the company whether those older versions are still supported, since the publisher’s current infrastructure and updates are built around the app.

Conclusion

Teaching Textbooks Geometry Version 4.0 packages a full year of high school geometry into a single app, combining animated lectures, automatic grading, and step-by-step problem solutions so students can work through the course largely on their own. At $79.95 for 12 months of access, plus a pause feature and indefinite gradebook access afterward, it is positioned as a low-maintenance option for homeschool families who want geometry taught and graded without daily parent involvement. Families deciding whether it fits their student should take the company’s free placement test, confirm the Algebra 1 prerequisite is solid, gather the required protractor and scientific calculator, and weigh the program’s independent, non-Common-Core sequence against their own curriculum goals before enrolling.

Frequently Asked Questions

What grade level is Teaching Textbooks Geometry Version 4.0 designed for?
It is designed for high school students who have completed Algebra 1, which is listed as a prerequisite. Teaching Textbooks’ full sequence spans grades 3 through 12, and Geometry sits between Algebra 1 and Algebra 2 in that sequence, typically corresponding to a standard high school geometry course.

Does Teaching Textbooks Geometry Version 4.0 work offline?
Yes, but only partially. The app supports offline use for up to six lessons at a time, after which the device needs to reconnect to the company’s servers to sync progress and access additional lessons. This makes it usable during short trips but not for extended periods without internet access.

Is a printed textbook included with Geometry Version 4.0?
No physical book is required to use the course, since the app includes a full, searchable eBook that can be viewed on screen or printed by a parent. Teaching Textbooks does sell optional printed textbooks separately for families who prefer a physical copy alongside the app.

How do I know if my student is ready for Geometry Version 4.0?
Teaching Textbooks offers a free, printable Geometry placement test built from Algebra 1 material and the geometry content in Pre-Algebra. The test has two 15-question sections, is taken without a calculator, and takes most students under an hour to complete.

How long does access to Geometry Version 4.0 last after purchase?
Enrollment provides 12 months of access to the student app, plus a three-month pause feature families can use during scheduled breaks. Access to the gradebook through the Parent Portal continues indefinitely after the enrollment period ends, so grade records are not lost.
