Highlights of this book

  • 478 problems, about 24 per chapter
  • Problems first (Part 1), answer key second (Part 2)
  • Final answers in bold and every step written out

Part 1 gathers the problems, chapter by chapter, in the order of the lessons. Inside each chapter, the first problems apply one idea at a time; the last ones mix several skills in word problems taken from everyday situations.

Part 2 is the answer key: every problem is solved step by step, with the final answer in bold. Keeping the solutions apart means the 20 chapters can be printed and worked on without the answers in sight.

Who is it for?

For a student taking high school Geometry, usually in tenth grade, and for the parents, tutors and homeschooling families who work with them.

The contents, chapter by chapter

How to use it in four steps

  1. Choose

    Pick the chapter of the next quiz or test at school.

  2. Solve

    Work the problems on paper without looking at the answer key.

  3. Check

    Compare each answer with the worked solution in Part 2.

  4. Redo

    A few days later, redo the problems that went wrong: that is where progress happens.

Questions from parents

How many problems are in the Geometry worksheets?

478 problems in 20 chapters, on 264 pages.

Does every problem have an answer?

Yes. Part 2 of the book solves every problem step by step and prints the final answer in bold.

Does it replace the school textbook?

It complements it: use it at home to review, practice or get ahead, whatever textbook the teacher uses.

Do I need the other two books of the grade?

No, each book works on its own. Together, the lessons, worksheets and tests of Geometry cover the three steps: understand, practice, check.

How is the book delivered?
