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

Being out of the room for a week is hard enough in Geometry, where the person covering your class usually cannot teach the content. This packet is built around that exact problem. It hands a substitute 5 complete class periods that need no preparation, no subject knowledge, and no grading.

Across the 5 days students work through foundations & angle relationships, triangles: congruence & similarity, right triangles & trigonometry, polygons, circles & area, surface area, volume & transformations. Every day is two pages. The first opens with a fully worked example of the day’s skill, so a student who gets stuck reads the page rather than asking the substitute a question nobody in the room can answer, and then works a set of scaffolded problems that move from straightforward to more demanding. The second page is a self-checking activity: the answers either trace a connected path through a grid or decode into a punchline, which means a wrong answer announces itself to the student and gets fixed without an adult ever adjudicating it. Each of those pages also carries a find-the-mistake exercise and a challenge problem for anyone who finishes early. The routine is the point: the same five-minute opener every day, so students settle without being asked twice.

A run sheet at the front tells whoever is covering exactly what to hand out each day and what to print, and a full set of answers waits at the back for your return. Every day stands on its own, so the set can run in any order, or a single day can be pulled on its own when you only need one. Designed for grades 9-12, printed in a clean low-ink layout, and equally at home in a homeschool schedule. Nothing here needs a calculator, a textbook, a login, or an internet connection.
