Six subtraction within 20 story problems with room to show working. Click New worksheet for a fresh sheet, then print it with its answer key.
About this worksheet
Math word problems with space to show working: addition, subtraction, multiplication, division, mixed operations and two-step problems. Each sheet has six short story problems with different names, objects and numbers, so no two sheets are the same. The answer key shows the calculation as well as the answer.
Tips for parents and teachers
- Read the problem twice, then ask: what do I know, and what do I need to find?
- Draw a quick picture or bar model before choosing an operation.
- Look at what is happening in the story (joining, taking away, equal groups) rather than hunting for key words.
- Write the answer in a sentence with its unit: '12 stickers', not just '12'.
