Description
How to Teach Subtracting Tens
This double digit subtraction without regrouping worksheet helps 1st grade students take away tens from a two-digit number. When a child subtracts 40 from 64, the ones digit stays the same and only the tens change, so six tens take away four tens leaves two tens and the answer is 24. Seeing that pattern again and again builds strong place value sense and makes mental math with tens feel easy.
About This Worksheet
Students solve twelve column subtraction problems. Each problem takes a multiple of ten away from a two-digit number, and none of them need regrouping. Children bring the ones digit straight down, subtract the tens column, and write the answer under the line in each box. The large print, roomy boxes and circled problem numbers keep the page calm and easy to follow. Every double digit subtraction without regrouping worksheet page is followed by the answer key; use it to check work quickly or to let students correct their own page.
What’s Included
- Twelve two-digit minus tens column subtraction problems, no regrouping
- Large answer boxes sized for 1st grade handwriting
- A full answer key
Why This Worksheet Helps Kids
First, it shows children that subtracting tens only changes the tens place, which is a key place value idea. Second, the no-regrouping problems let students build speed and confidence before they meet borrowing. Third, the column format gets kids ready for the standard subtraction method they will use in 2nd grade and beyond.
Ideas for Teachers and Parents
Before starting, model one problem with base ten blocks: build 64 with six rods and four cubes, then take four rods away. Have students say the tens aloud as they subtract. For early finishers, ask them to write a new problem that follows the same rule and trade with a partner. This 1st grade subtraction worksheet also works well as a warm-up, homework page, or quick check before you teach regrouping.
