Regrouping into blocks of 10

Before handing out the worksheet, briefly introduce the concept with a short oral warm-up or a visual model on the board. Let students work through the first item together as a class, then finish the rest independently or with a partner, encouraging them to talk through their thinking: "What strategy are you using? How do you know that is right?" After completing the worksheet, review any missed problems together and discuss the reasoning rather than just the answer. For extra support, let students use manipulatives or draw pictures alongside the written problems. These base 10 blocks worksheets work well as daily practice, homework, or a focused review activity.

These base 10 blocks worksheets for 1st grade give students the structured, hands-on practice they need to build confidence and fluency. Students work through a range of problem formats, from visual models and diagrams to written equations and word problems, so they encounter base 10 blocks from every angle. Each worksheet is designed to build on prior knowledge while introducing the level of challenge appropriate for 1st grade. Practicing base 10 blocks at this stage strengthens the mathematical foundations that support more advanced concepts in later grades.

Yes, both. We made it for 1st Grade base 10 blocks, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

Their proportional size - a rod is exactly 10 times a unit cube - makes the relationship between tens and ones physically and visually concrete.

Students sometimes count rods as single units rather than tens; explicit instruction that each rod equals 10 units prevents this miscounting.

After identifying the number from the blocks, students write the numeral - closing the loop between the concrete model and abstract number symbol.

19 printable worksheets, all free to preview. Downloads are included with a ClassWeekly free trial, and every page prints on standard 8.5 x 11 paper.

These are written for 1st Grade students, roughly ages 6-7. Many teachers also use them a grade up for review or a grade down as an extension, so use the preview to judge the fit for a particular child.

Yes. Each one shows the Common Core code it covers on its own page, so you can check the alignment yourself rather than taking our word for it.

Yes. Nothing here assumes a classroom of 25, so they work the same one-to-one at the kitchen table as they do in a 1st Grade classroom, a literacy centre, or a tutoring session.
