This is the preview. Hit "Print this worksheet" above to open a clean, ad-free, one-page version with name and date lines and writing space for each problem. A separate answer key prints on the second page for the grown-up. Tear it off before handing the practice page to your child.
Designed for Grade 2 learners, this printable explores Open number-line subtraction through clear, scaffolded problems that grow in difficulty across the page so kids hit a stretch challenge after the easy warm-up.
We organize the page so the easier warm-up problems sit at the top and the more challenging stretch questions sit near the bottom, giving students a confidence boost before they reach the harder work. By the end of the page, learners should be able to explain their strategy in a sentence, not just write an answer.
Pair the worksheet with manipulatives (counters, base-ten blocks, fraction tiles, two-color discs) for students who still need concrete support before moving to abstract symbols. The concrete-pictorial-abstract progression is one of the most reliable moves in elementary math.

Parents tell us the most useful thing about this Open number-line subtraction page is how fast they can hand it to a kid. No login. No PDF locked behind an email gate. Click print, hand it over, get ten quiet minutes of real math practice without prepping anything.
This worksheet is aligned to Common Core State Standard CCSS.Math.2.NBT and supports the broader Subtraction within 100 progression that students continue to build through later grades. The same skill is revisited each year with greater abstraction, so the work your student does on this single sheet feeds into the multi-digit and multi-step problems they will see in middle school.
Pair this Open number-line subtraction worksheet with the rest of the Grade 2 Subtraction within 100 collection for a focused practice block that covers the standard from several angles in a single afternoon.

How to use this worksheet
Print one copy per child on standard letter or A4 paper. Set a quiet 10 to 15 minute window. Hand your student a sharpened pencil and an eraser, and let them work top to bottom. The first row is a warm-up on purpose. The last row is a stretch on purpose. Sit with them as they finish so any misconceptions surface right away instead of getting practiced into a bad habit.
If your student finishes quickly, flip the page over and ask them to write two new problems of their own that target the same skill. It's a powerful retention move. If they get stuck, pull out manipulatives that match the skill (counters for early addition, base-ten blocks for place value, fraction tiles for fractions) and work through one or two problems together before letting them try the rest on their own.
