What does this worksheet teach?⌄
These addition with 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 addition with 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 addition with base 10 blocks at this stage strengthens the mathematical foundations that support more advanced concepts in later grades.
What grade level is this addition with base 10 blocks worksheet for?⌄
"Addition with base 10 blocks" is written for 1st Grade (Ages 6-7), and it covers Common Core 1.NBT.C.4. If your little one is a year younger but already steady on base 10 blocks, the page still works. You may just need to read the instructions out loud. And if they are older and addition with base 10 blocks never quite stuck, this is a short review rather than busywork.
Can I use this addition with base 10 blocks worksheet for homeschool or classroom?⌄
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 with addition with base 10 blocks. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.
How does adding with base-ten blocks prepare students for column addition algorithms?⌄
The blocks make it natural to add tens to tens and ones to ones separately, which is exactly the logic behind the standard column addition algorithm.
What types of addition problems appear on base-ten block addition worksheets?⌄
Problems typically include adding two two-digit numbers, a two-digit and a one-digit number, and adding multiples of ten - all without regrouping at this stage.
When should regrouping with base-ten blocks be introduced?⌄
After students are comfortable with no-regrouping addition using blocks, regrouping can be introduced by physically trading 10 unit cubes for a rod.

I print a stack Monday morning and I'm set for the week. My sub folder is entirely ClassWeekly at this point.

Printing is the part that usually goes wrong and it never does here. What I see on screen is what comes out of the copier.
