Practice Addition and Subtraction Word Problems Within 50

Use these addition and subtraction task cards with mini whiteboards, maths notebooks, and smart boards for a quick operations lesson warm-up.

Through this activity, students will show they can add to, take from, put together, take apart, and compare numbers less than 50. 

For example, one card includes the following word problem: 

Naomi has joined a hockey team. The coach has 19 extra jerseys. 7 new players join the team and need jerseys. How many extras are left?

An answer sheet is included with your download for students to self-check their answers. 

Scaffolding + Extension Tips 

Support struggling students by providing manipulatives to assist them with solving the problems. Alternatively, provide students with our Problem Solving Mat to help them organise their ideas. 

Challenge fast finishers who already understand the concept to write five different problems for a partner to solve.

How to Use Our Addition and Subtraction Word Problems

A team of dedicated, experienced educators created this resource to reinforce your maths lessons in the following ways: 

🏫 Whole Class Instruction

Project the task cards on a whiteboard and work through each together, discussing different ways of approaching and completing the problems.

🧮 Small Group 

Teach concepts in a small group setting in your maths rotations. Students can use mini whiteboards to ‘show and share’ their work for each problem.

✏️ Individual Practice

For an independent task, students can use a sheet of paper numbered 1–20 (or a mini whiteboard) and the task cards. Students will solve for the sum or difference and check their work.
