Working with the Glencoe Geometry textbook and its tech integration
The Glencoe Geometry series by McGraw-Hill is a standard high school curriculum that tries to tie geometry into real applications, cross-disciplinary connections, and technology use. It covers the usual topics—congruence, similarity, circles, area, volume, coordinate proofs—with each chapter ending in what the publisher calls "Applications" and "Connections" sections, and the accompanying technology guide covers graphing calculators and dynamic geometry software like Geometer's Sketchpad or GeoGebra. I have used this material in classrooms and tutored students through it, so I know where the friction points actually are. The textbook itself is fine for the core content, but the "tech integration" portion is where most people stumble. The book references calculator procedures and software steps in a way that assumes a level of digital literacy students rarely have at that point. You will spend more time teaching the tool than teaching the geometry if you follow the tech sections verbatim.
Getting started with Glencoe Geometry Integration Applications Connections Tech
Before you assign anything, pull the teacher edition and scan the technology notes for the first five chapters. The publisher marks which lessons include calculator or software activities, and they are not evenly distributed. Chapters 1 through 3 lean heavily on the TI-83/84 family for basic graphing and measurement verification, while later chapters shift toward dynamic geometry software for exploration. The real workflow that works in practice looks like this. Start with the direct instruction from the main lesson. Give students the geometric concept and let them work through the examples on paper first. Then, and only then, introduce the technology as a verification or exploration tool, not as the primary learning mechanism. I have seen teachers flip this order and watch students copy calculator outputs without understanding what the numbers mean. One specific edge case I ran into repeatedly involved the "Applications" sections in the Circles chapter. The textbook asks students to use a graphing calculator to approximate arc lengths and sector areas given a central angle and radius. The procedure assumes students already know how to set their calculators to radian mode, which is something the book does not explicitly state until a later subsection. If a student is in degree mode and follows the example exactly, they will get answers that are off by a factor of roughly 57. This happened to at least three students in my class before I caught the pattern. The workaround was simple: I put a permanent radian-mode reminder on the board and had students check a quick reference problem before attempting the application exercise. That saved about ten minutes per period.
Common pitfalls that beginners miss
The first thing people overlook is that the Connections sections often reference material from algebra, physics, or even art. These are not optional supplements. They are integral to how the curriculum builds procedural fluency across subjects. When a student skips the connection to proportional reasoning, the later similarity proofs become much harder because the underlying algebraic manipulation is weak. I found that reviewing the relevant algebra topics for ten minutes before jumping into a Connections exercise improved completion rates significantly. A second counter-intuitive point is that the textbook's technology activities are actually more useful for diagnostic purposes than for instruction. Run a short Sketchpad or GeoGebra exploration at the start of a unit, not after. You will immediately see which students have spatial reasoning strengths and which are struggling with the conceptual foundation. The end-of-chapter tech activities tend to be procedural checklists that confirm understanding the student may never have developed.

What this approach does not do well
The Glencoe Geometry series has clear limitations. The technology integration is dated in several editions, especially the older ones that reference GeoWorks or early versions of dynamic geometry software that no longer run on modern operating systems. If you are working with a newer TI-Nspire, some of the button sequences in the text are slightly off. You will need to cross-reference with Texas Instruments' current documentation, which takes about five to ten minutes per referenced lesson. The applications sections also tend to use simplified or unrealistic scenarios. Problems about calculating the area of a garden plot or the volume of a silo are fine for practice, but they do not reflect the kind of messy, constrained geometry work students will encounter in STEM fields. If your goal is college or career readiness beyond the standard geometry course, you should supplement this textbook with project-based tasks that involve actual measurements, error analysis, and constraints. I have used free online tools like Desmos for this purpose, and it usually takes about twenty minutes to set up a meaningful activity once you have a template. The curriculum also assumes consistent access to graphing calculators or computers. In environments where device availability is limited, the tech integration becomes another equity issue. In those cases, I drop the software components and replace them with compass-and-straightedge constructions that the book already covers as alternative explorations. The geometry learning outcomes remain the same, and you avoid the logistical headache entirely.
Where to find the materials
The Glencoe Geometry Integration Applications Connections Tech resources are distributed through McGraw-Hill's official channels. The main textbook and workbooks are available through standard educational retailers. The teacher edition, which contains the full answer key, technology notes, and additional application problems, requires a verified educator account on the publisher's site. Some editions include a technology activity CD or a download code inside the back cover. If you are using a newer print version, the tech components are hosted on McGraw-Hill Connect, and you will need an access code from your institution. For the dynamic geometry exploration files specifically, search the publisher's support portal for the Glencoe Geometry technology activities. The files are usually organized by chapter. I recommend downloading everything at the start of the term rather than per lesson, because browser compatibility issues can occasionally prevent individual files from opening later. There is no single reliable third-party source for these materials. Sites that offer PDFs of the entire textbook or leaked answer keys are violating copyright and often contain outdated or corrupted versions. The content has been revised across multiple editions, so an older file may not match the problems your students are actually working on. Stick to official channels to avoid that mismatch.
A practical sequence for the first month
If you are planning to implement this curriculum, here is a sequence that has worked without excessive friction. Week one covers Chapter 1 introductory topics. Use the textbook for definitions and worked examples. Skip the technology component on the first day. On day two, run a quick calculator verification activity with the standard TI-84 procedures from the book. Give students a short worksheet with five problems to check by hand and five to verify with the calculator. This contrast builds the habit of using technology as a check, not a crutch. Week two moves into angles and triangles. Introduce the Connections section that ties angle relationships to basic algebra. Have students solve for unknown angle measures using algebraic expressions before touching any tool. The algebra connection is the harder skill here, and the geometry is actually the easier part if they can set up the equation correctly. By week three, you can introduce a simple GeoGebra or Sketchpad activity from the tech guide. Keep it under fifteen minutes. The goal is familiarity with the interface, not mastery. Students who spend too long fiddling with the software in the first month lose momentum on the actual geometry content.
The book itself is solid for teaching standard geometry. The tech integration adds value when treated as supplementary rather than central. The applications and connections sections are where the curriculum differentiates itself from older formats, but they require the teacher to bridge gaps the book leaves open. If you budget extra time for those bridges and keep the calculator and software work focused on verification, the materials work well. If you try to run every tech activity as a standalone lesson, you will fall behind the pacing schedule within three weeks.
