Worksheets and Tests in Seconds, With Answer Keys

Building a fresh worksheet from scratch every week is the part of the job that quietly eats your evenings. The same goes for differentiated practice — three versions of the same exercise for three reading levels is an hour you don't have on a Sunday night.

The Spelling Worksheet Generator and Worksheet Generator produce print-ready worksheets with the answer key on a separate section. Pick the grade, the topic, and the question types — fill-in-the-blank, short answer, matching, multiple choice — and you have a teacher copy and a student copy in under a minute.

For weekly assessments, the Spelling Test Generator builds quizzes with sentence prompts, and the Random Math Problem Generator creates problem sets from arithmetic through calculus, each with worked solutions you can put on the answer key.

Faster, Fairer Grading and Feedback

The bottleneck isn't reading the essays — it's writing the same comments fifty times. “Strong thesis but the second paragraph wanders.” “Cite this claim.” “Watch your transitions.” By essay thirty, your handwriting is a scribble and your patience is gone.

The AI Essay Grader gives you a rubric breakdown — thesis, evidence, structure, mechanics — with specific quotes from the essay and a suggested grade band. Use it as a starting point, then adjust before posting. The Essay Reviewer focuses on grammar, structure, and argument flow for student drafts and revisions.

For everything that isn't a full essay, the Feedback Generator writes specific, constructive comments on student work — assignments, projects, presentations. The output sounds like you, not a chatbot, so you can paste it directly into the gradebook.

Try the Essay Grader
Example Rubric Comment
Thesis (4/5): The claim is clear but appears in paragraph 2. Move it to the end of the intro and the rest of the essay will land harder. Evidence (3/5): Strong primary source in §3. The §4 claim about voter turnout needs a citation.

Discussion Boards, Prompts and Lesson Hooks

Online discussion boards live or die on the prompt. “What did you think of chapter 3?” gets twelve one-line replies. A specific, opinionated prompt gets actual conversation. Same goes for essay topics and bell-ringers — the framing is most of the work.

The Discussion Post Generator writes prompts that force students to take a position with evidence, and the Discussion Response Generator gives you five model replies you can use as exemplars or for grading rubrics.

For new units, the Essay Prompt Generator and Random Subject Generator hand you topic banks across every discipline — perfect for choice-based assignments, sub plans, or warm-up writing.

Try the Discussion Post Generator
Example Discussion Prompt
Some historians argue the New Deal saved capitalism by reforming it; others argue it permanently expanded federal power beyond the Constitution's intent. Which reading better explains the 1935 Social Security Act? Cite at least two specific provisions.
