Grade 9 Grade Kit: Printable Geometry and English Practice (PDF)

The Grade 9 Grade Kit is a 142-page printable practice kit for students ages 14 to 15, for home, homeschool or classroom. The pages have a clean, grown-up look made for high school students. Twenty to thirty minutes a day is plenty.

• Language and writing, 10 pages: gerund, infinitive and participial phrases, clauses and colons, subordination and modifiers, verb tense and usage, diction and syntax, quoting and citing sources, manuscript form in MLA style, a response to literature, an expository essay and a persuasive essay.
• Study tools, 7 charts: geometry formulas, angles, lines and circles, right triangles and trigonometry, proof reasons, lines and systems, polynomials and quadratics, and grammar and writing.
• Puzzles, 7 pages: Theorem Match cards, a proof puzzle, an angle chase, a logic grid, geometry riddles, cryptograms and two Math Cages puzzles.
• Super Smart Challenge, 24 pages: optional pages that reach two grades up, to Grade 11 level. Radians and the unit circle, graphs of sine and cosine, trigonometric identities, sum and double-angle formulas, the law of sines, the law of cosines and triangle area, inverse trigonometric functions, polar coordinates, vectors, ellipses and hyperbolas, rational functions and asymptotes, polynomial division and roots, composition and inverse functions, the binomial theorem, standard deviation and the normal distribution, words from government and history, satire and parody, analyzing a public document, American literary periods, imagery and sound in poetry, the gas laws, electricity and magnetism, the Great Depression and the New Deal, and the civil rights movement. Each page teaches first, then lets the student try.

Good to know

Traditional, skills-first practice based on California's pre-Common Core standards (math and English language arts, 1997; science and history-social science, 1998). Grade 9 math here is the 1997 Geometry course, with a review of Algebra I. English pages follow the Grades 9 and 10 standards, and the science true-facts pages follow the high school science standards. California's history-social science standards set no required Grade 9 course, so the history page uses the Grade 10 standards. The challenge pages follow California's 1997 Trigonometry, Mathematical Analysis, Algebra II and Probability and Statistics standards, the Grades 11 and 12 English standards, and the Grade 11 history standards. Not affiliated with or endorsed by the California Department of Education. States set their own standards. Check yours.

This kit is supplemental practice, not a curriculum. It was made with AI assistance. Every math answer in the key is computed by code and checked (answers marked Sample are models), and each science and true-facts page is checked against at least two reference sources, listed at the end of the answer key.

Some pages are shared with our other kits: 24 Grade 9 level pages (15 math, 2 reading, 4 true-facts and 3 language pages) also appear as the Super Smart pages of our Grade 7 Grade Kit. The lines and systems chart and the polynomials and quadratics chart also appear in our Grade 8 kit. The geometry formulas chart, the right triangles and trigonometry chart and the grammar and writing chart also appear in our Grade 10 kit. The 24 Super Smart pages (Grade 11 level) also appear as regular pages in our Grade 11 Grade Kit. If you own those kits, you already have them.

Print on US Letter paper. The inside pages print well in black ink; the cover looks best in color. Print the cut-out page (the Theorem Match cards) on one side only, on heavier paper if you have it.
