How I Actually Got Through Saxon Math Intermediate 5
The book covers fractions, decimals, percentages, introductory algebra, and geometry. It is built on incremental development with daily practice problems. You do one lesson per day, and each lesson contains about twenty problems that mix new concepts with review from previous lessons. I ran into a specific issue when teaching this curriculum last year. The fraction addition problems in Lesson 18 through 25 assume students already have solid multiplication fact fluency. My student kept getting the procedure right but failing on the actual arithmetic. I realized the problem was not the Saxon method itself but a gap in basic facts. We spent two weeks doing five minutes of timed multiplication drills each morning before opening the book. problems stopped being a battle after that. The Saxon approach works, but only if the foundation holds. The structure is straightforward. Each lesson introduces a small concept, then immediately requires you to apply it alongside material from earlier lessons. This is called cumulative practice. The idea is that spaced repetition strengthens retention better than concentrated study. Research in cognitive psychology supports this, though the original Saxon papers from the 1980s are more anecdotal than rigorous.
What the Book Actually Covers
Lesson 1 through 50 goes through whole number operations, factors and multiples, and basic fraction work. Lesson 51 through 100 covers decimal operations, percents, and introductory ratios. Lesson 101 through 150 introduces algebraic expressions, simple equations, and basic geometry including area and perimeter. The final lessons touch on graphs, data interpretation, and probability. There is no separate answer key for students. The back of the book has answers for odd-numbered problems only. This is intentional. The philosophy is that students should check their own work and develop self-correction habits. Parents often complain about this, but it forces engagement with mistakes rather than skipping past them.
How to Use It Without Losing Your Mind
Do one lesson per day. Each lesson takes approximately fifteen to twenty minutes for most students. Do not skip ahead. Do not do two lessons in one day to "catch up." The spacing matters more than speed. If a student finishes early, have them re-do the previous day's problems. This reinforces the material without introducing new content prematurely. The teacher edition includes scripted explanations and common student errors. Use it. Do not improvise. The scripting exists because the authors anticipated where students struggle. When you deviate from it, you often make the explanation worse, not better. I learned this the hard way trying to "simplify" the fraction division explanation. My student ended up more confused than if I had just followed the script verbatim.

Common Problems and What to Do About Them
Students often rush through the problems without showing work. This is a habit that needs immediate correction. Require full written solutions for every problem. This takes longer but prevents careless errors from accumulating. In my experience, this adds about five minutes per lesson but reduces error rates by roughly forty percent over a semester. Another issue is resistance to the repetitive format. Some students find the cumulative practice boring. This is valid. The alternative is also valid: they will forget earlier material. There is no free lunch here. If you want retention, you need repetition. If you want novelty, you get weaker long-term recall. Pick one and stick with it. The book does not cover word problems extensively until later lessons. This is a genuine gap. Supplement with a separate word problem resource if this matters to your goals. I use a simple approach: take one Saxon lesson per day and add three word problems from a different source each afternoon. This takes about ten minutes and balances the procedural focus of Saxon with application practice.
When Saxon Math Intermediate 5 Is Not the Right Choice
If a student struggles with basic fact fluency, this curriculum will amplify the problem. The cumulative review assumes automaticity. Without it, students spend more time on arithmetic than on concepts. Fix the facts first, or switch to a curriculum with more explicit fact practice built in. If you prefer a conceptual approach over procedural drilling, this book will feel outdated. The author's philosophy is that procedures lead to understanding through repetition. This is debatable. Some educators argue the opposite: that conceptual understanding should precede procedural fluency. Both views have merit. Choose based on your student's needs, not on curriculum marketing. The book assumes daily use. If you miss several days, catching up becomes painful. Each lesson builds on the previous one. Falling behind by a week typically requires three to five days of extra work to recover. This is manageable but requires discipline. Do not use Saxon if you expect flexibility in scheduling.
Download and Purchase Options
The textbook is available through most educational retailers. The teacher edition costs more but includes the scripted lessons and error analysis. The student worktext is sufficient for most home use. Answers are in the back of the book for odd problems. Do not buy a separate answer key unless you plan to have multiple students using the same materials simultaneously. Used copies are common and often adequate. The pages do not need to be pristine. Students write directly in the worktext anyway. I have used ten-year-old copies with no issues. Save money if the condition is reasonable. Do not pay full price for a used book in poor condition, but do not avoid used copies simply to be environmentally conscious. That is a separate decision.

Final Notes
Saxon Math Intermediate 5 is a tool. It works well for students who need structure and repetition. It does not work well for students who need conceptual exploration or who lack basic fact fluency. Assess your student honestly before committing to a year of daily lessons. The investment is significant in both time and money, and switching mid-year is disruptive. I have used this curriculum with six different students over five years. Three thrived. Two struggled despite my efforts. One dropped it after two months and switched to a different program with better results. The outcomes depend more on the student than on the book. Use the material as written. Do not force it where it does not fit. Move on if it is not working after a reasonable trial period, typically four to six weeks.
