What This Book Actually Does
The Houghton Mifflin Math Practice Book Grade 4 is a supplemental workbook that follows the same scope and sequence as the main Harcourt Math textbook. It's not the primary curriculum. It's the daily or weekly practice problems that go with the chapters your kid is already covering in class. Each lesson gets a page of drills, a mix of computation and word problems, and a short assessment at the end. I've watched parents buy this thinking it would replace the teacher's assignments. That doesn't work. The problems are too sparse and too closely tied to the exact teaching method the classroom uses that week. If the teacher is working through long division with a specific regrouping visual, the workbook page assumes your kid saw that in class. Without that context, the kid stares at the problem and blanks out. I had that happen with my own kid last year on the multi-digit multiplication set. We just pulled up a Khan Academy video on the same topic and came back to the page. Worked immediately.
Houghton Mifflin Math Practice Book Grade 4 — Where to Get It
The book is ISBN 978-0-15-335865-4 for the student practice edition. You can find used copies on Amazon, eBay, or BookDepository. The new retail price runs about $18 to $24 depending on the seller. Some schools include it in the supply list and provide a digital access code through their platform, usually powered by Savvas Realize or the older Harcourt school portal. There are also free PDF practice pages floating around education sites like Scholastic and various teacher blogs. The quality varies because those are often scanned from older editions. Make sure the chapter numbering matches the current Harcourt Math Scope and Sequence if you're using this at home to stay aligned with what's happening in class that week.
How It's Organized
The book runs through roughly eighteen chapters covering the standard fourth-grade math standards. Place value through millions, addition and subtraction with regrouping, multiplication and division facts through 12, multi-digit operations, factors and multiples, fractions with unlike denominators, decimal introduction, measurement conversion, geometry angles and lines, and data graphs. Each chapter has between four and eight lessons, and each lesson is one printed page. The structure within each page is predictable. You get a mini example at the top showing the procedure, six to ten guided problems, then a mixed review set that pulls from previous chapters. The mixed review is actually the most useful part. That's where retention happens. The new-concept problems are just repetition of whatever the teacher showed that morning. One thing people miss about this workbook: the difficulty curve is flat. Chapter 1 and Chapter 12 feel roughly the same effort level until you hit the fractions unit. The fraction word problems in chapters twelve through fourteen are where kids typically stall. I saw it every year. The multiplication and division chapters are straightforward procedural work. The fractions and decimals chapters require conceptual understanding that the workbook doesn't always build slowly enough. My workaround was pairing the fraction pages with physical fraction tiles or printed paper circles so the kid could see what "common denominator" actually looks like instead of just memorizing the algorithm.

Using It Effectively at Home
The most common mistake is assigning random pages. That wastes time and creates gaps. The right approach is to sync it with the school schedule. Ask the teacher which chapter is current, then do one lesson per day, five days a week. That usually covers a chapter in a week, which is how the pacing works in most fourth-grade classrooms. Keep a timer going. Most pages take between eight and fifteen minutes. If a page is taking longer than twenty minutes, the kid doesn't understand the concept, not the math. Stop and go back to the textbook or a video. Pushing through frustrated is how bad habits form around math. I also recommend grading it yourself instead of letting the kid self-correct. The answer key is in the back of the book, but kids will second-guess their answers when they see the key before they're confident. Check it, mark wrong answers in red, have them redo only the incorrect problems. This cuts correction time down from a full page redo to maybe three or four problems. Takes about five minutes total instead of twenty.
When This Book Falls Short
It doesn't cover all fourth-grade standards. The state test prep questions are thin. If your kid is preparing for a standardized exam, this workbook alone won't prepare them adequately. You'd need a separate test prep resource for that. Also, the word problems are sometimes unrealistic. They use scenarios like ticket sales and library book counts that don't reflect the kinds of problems on modern assessments, which tend to use more diverse contexts and multi-step reasoning. Another limitation: there's no spiral review beyond the mixed problems at the bottom of each page. Once a chapter is done, the book moves on. There's no deliberate return to earlier topics. That's fine if the classroom teacher is handling spiral review, but at home you'll need to add it yourself or the kid will forget place value concepts by November. For kids who need extra support, this book isn't remedial. It's parallel practice. If your kid is behind in math, working through this page-by-page without extra instruction won't close the gap. In those cases, I'd recommend pairing it with an online platform like IXL or DeltaMath where the adaptive questions catch gaps the workbook misses. The combination of workbook for alignment and adaptive tech for remediation is what I ended up using consistently, and it produced better results than either one alone.
