Geometry Emergency Sub Plans - 5 Days No Prep Self-Checking Worksheets

Five full days of substitute-ready Geometry in one no-prep download, built for the problem that makes a math absence hard: the person covering your room almost certainly cannot teach the Pythagorean Theorem or the interior angle sum. Nothing here asks them to. Every page opens with a fully worked example that states every rule that page needs, every second page checks its own answers, and a run sheet at the front tells the substitute exactly what to hand out. The five days run in course order, so the set can be handed over as a week or pulled one day at a time. You come back to a complete set of answer keys and a class that kept working.

WHAT'S INCLUDED

- Sub & Teacher Notes run sheet (what to hand out each day, what to print, and why the substitute does not need to grade anything)

- 5 days of student work, two pages per day (110 problems total)

- 5 complete answer keys, one per day

- Single 17-page PDF: run sheet and student pages first (pages 1-11), an "Answer Keys" divider on page 12, then the keys (pages 13-17) -- print pages 1-11 to hand out the whole week without printing the keys

- PDF bookmarks for one-click navigation by day

- US Letter, low-ink, two-sided printable

WHY A SUBSTITUTE CAN ACTUALLY RUN THIS

- Every page opens with a fully worked example, so a stuck student reads the page instead of asking the sub a math question

- Every second page checks itself -- answers trace a path through a maze or spell out a punchline, so a wrong answer is caught by the student, not adjudicated by the sub

- Every day has an "if you finish early" challenge, so nobody runs out of work

- No calculator, textbook, login, or internet needed

THE 5 DAYS

1. Foundations & Angle Relationships -- points, lines and planes, complements and supplements, parallel lines and transversals (25 problems, decoder)

2. Triangles: Congruence & Similarity -- angle sums, congruence shortcuts, the triangle inequality, similarity and midsegments (20 problems, maze)

3. Right Triangles & Trigonometry -- the Pythagorean Theorem, special right triangles, sine, cosine and tangent (22 problems, decoder)

4. Polygons, Circles & Area -- interior and exterior angles, arcs and chords, circumference, and composite area (19 problems, maze)

5. Surface Area, Volume & Transformations -- prisms, cylinders, cones and spheres, plus translations, reflections and rotations (24 problems, decoder)

Each day stands alone, so they can run in any order or be pulled one at a time.

PERFECT FOR

- Emergency and planned substitute days in Geometry (grades 9-12)

- Planned absences, professional development days, and testing weeks when you are pulled to proctor

- Review before a test, the first week of school, or the day before a break

- Homeschool families working through Geometry

STANDARDS TOUCHED

Common Core Math: HSG-CO.A.2 (transformations described as functions that take points in and give points out), HSG-CO.B.6 (predicting the effect of a rigid motion on a figure), HSG-SRT.B.5 (using congruence and similarity criteria to solve problems), HSG-SRT.C.8 (trigonometric ratios and the Pythagorean Theorem in applied problems), HSG-C.A.2 (relationships among inscribed angles, radii and chords), HSG-GMD.A.3 (volume formulas for cylinders, cones and spheres), and HSG-MG.A.1 (using geometric shapes and their measures to describe real objects).
