3rd Grade Math Homework – Week 21
Ten ready-to-print homework sheets for week 21 of the school year, each one page on US Letter with a box for teacher comments and a parent signature, plus an answer key for parents. Preview them, then download one sheet or all ten in a single PDF.
What week 21 covers
This week’s topics
- Multiplying by multiples of 10
Review of earlier topics
Multiplication facts · Division facts · Multiplication and division word problems · Unknown factors · Time to the minute · Elapsed time · Mass and liquid volume word problems · Rounding to the nearest 10 or 100 · Addition within 1,000 · Subtraction within 1,000
Every sheet has a multiple-choice part and a show-your-work part: about two thirds of the questions come from this week’s topics and one third reviews earlier ones. The 10 sheets use different numbers and questions, so you can give each student a different one or use them over several days.

Frequently asked questions
Does week 21 match my school’s curriculum?
Not exactly. The weeks follow the order these topics are commonly taught in 3rd grade, spread over a 35-week school year. It’s an estimate, not any program’s pacing guide, so if your class is ahead or behind, pick the week whose topics match what you’re teaching.
Where is the answer key?
Every downloaded sheet has an Answer Key for Parents page right after it. When you download all 10 sheets, the 10 answer keys come at the end of the file, so you can print only the sheets for students. Turn on Show answer key on this page to preview it.
Can I edit a sheet?
Yes. Open the Weekly Math Homework Generator, choose Grade 3 and week 21, and type the sheet number (for example 32101) into the Sheet number box: with the default settings you get the same sheet. Then change the topics or the number of questions, or add a challenge question.
Want to choose the topics yourself?
Use the homework generator to tick your own topics, change the number of questions, add a challenge question or make a new sheet any time.
