Subbing for a high school class you know nothing about? Get 4 standards-aligned activities for 9th through 12th graders — linear functions, rhetorical analysis, experimental design, and more. Real academics, not busy work.
Get High School Activities →Here's what SubDesk generates for 9th–12th grade classrooms. Intellectually rigorous activities that high schoolers will actually engage with.
Students explore slope and y-intercept using real-world data — hours studied vs. test score. Plot points, draw a line of best fit, calculate slope, and make predictions.
Students analyze persuasive techniques in a speech or advertisement — identifying ethos, pathos, and logos. Annotate the text, evaluate effectiveness, then write their own.
Students design a controlled experiment to answer "Does music affect concentration?" — hypothesis, variables, procedure, measurement strategy, and peer review.
Students analyze 3-4 historical source documents, evaluate reliability and bias, then write a thesis statement and outline an evidence-based argument.
Three steps. No district login. No training required.
