Third grade is a big transition year. Students move from learning to read toward reading to learn, start multiplication and division, and in most states take their first state tests in the spring. A good 3rd grade sub plan reflects that: real reading passages with text-based questions, multiplication fact fluency and word problems, and a writing task with a clear structure. Third graders can work independently for 15 to 20 minutes, so build the day around a few solid tasks rather than many tiny ones.
Use short informational passages with questions that require evidence from the text, a core skill throughout grade 3.
Fact practice and arrays are perfect sub work in third grade: easy to explain, easy to check and always useful.
A paragraph frame with a topic sentence, three details and a closing helps students write independently.
Answer keys for math let the sub or a student helper check work quickly and keep the class moving.
Third grade sub plans can stall when a passage is too hard to read independently, so check that texts sit at or just below grade level. Avoid introducing a new multiplication strategy or fraction concept, which the sub cannot reteach if students get confused. Long writing tasks without an organizer also tend to produce very little. Leave an extra read-aloud book and a math game the class already knows, so the sub has a calm back-up if a lesson finishes early or the schedule changes.
Mix and match to fill the period. Every one works on paper with no specialist knowledge.
A one-page multiplication or addition fact practice matched to where the class is, timed for five minutes and self-checked.
A grade 3 passage on an animal, invention or place, with questions on main idea, text evidence and vocabulary.
Students draw arrays for multiplication facts, then solve four one- and two-step word problems with a show-your-work box.
A prompt like 'Should recess be longer?' with a graphic organizer for reasons and a paragraph frame.
Students place unit and simple fractions on number lines and shade fraction models, matched to grade 3 fraction work.
The sub reads a chapter or picture book aloud, then students answer two discussion questions with a partner.
The checklist that stops the sub day going wrong before it starts.

Yes. Choose Grade 3 and a tested skill, such as main idea or multiplication word problems, and the questions practice that skill with an answer key. For full test-style practice, use the test generator.
Fifteen to twenty-five minutes works well. Third graders can sustain independent work for that long, especially with a clear checklist and a fast-finisher task.
