Get your students moving while they master addition with Mathsercise Coding: Two-Digit Add Two-Digit Worksheets. This engaging activity blends maths, fitness and coding into one fun, collaborative task that your students will love. With a focus on two-digit algorithm addition, it offers a hands-on way to practise written strategies while building classroom energy and teamwork.

Students begin by solving a set of two-digit addition equations. Then, using a simple number-to-letter code, they decode a hidden exercise prompt - for example, “10 star jumps” or “jog on the spot.” Once they’ve cracked the code, they perform the action. But the fun doesn’t stop there! In the second part of the activity, students become the coders. They create their own addition problems, encode a secret movement, and challenge a classmate to solve, decode and complete it.

Three differentiated worksheet versions are included to suit a range of ability levels. The first version avoids regrouping, the second includes some regrouping, and the third requires regrouping in every equation. This means you can target the right level for each student, or progress through all three versions together as a class. All featured exercises can be performed in a classroom, playground, or covered area with no equipment needed.

Key Learning Outcomes:

• ✅ Accurately solve two-digit addition equations using written algorithms
• ✅ Apply knowledge of regrouping strategies when required
• ✅ Practise basic coding principles through number-to-letter substitution
• ✅ Improve maths fluency through repetition in a fun, active format
• ✅ Build teamwork and creativity through peer-coded activities

What’s Included:

• 3 differentiated worksheet versions:
  • - No regrouping
  • - Some regrouping
  • - All regrouping
• Built-in code key and space to record the decoded exercise
• Challenge section for students to create and swap their own code
• Print-ready format suitable for individual, paired or small group work

Materials Needed:

• Printed worksheets (one per student or pair)
• Pencils or pens
• Space to perform movement activities (classroom, hall, or playground)

How to Use:

1. Choose the worksheet version that suits your students’ current level.
2. Students solve the addition problems and record their answers.
3. They use the provided code to match answers with letters and reveal a secret exercise.
4. Students perform the exercise before moving on to the challenge activity.
5. In the second section, students create their own equations and encoded message to swap with a classmate.

Ideas for Classroom Use:

• 💡 Use during a maths warm-up or energiser block
• 💡 Set up as a numeracy and movement station in rotations
• 💡 Assign different versions based on student readiness for regrouping
• 💡 Pair students for the challenge section to encourage peer-to-peer learning
• 💡 Use outdoors for a high-energy maths session

Top Teacher Tips:

• 💛 Model decoding an example together before students begin
• 💛 Offer number lines or place value mats for students needing regrouping support
• 💛 Encourage creativity in the peer-coded movement challenges
• 💛 Use the worksheets as a quick formative check for regrouping confidence

Mathsercise Coding: Two-Digit Add Two-Digit Worksheets is a fun and flexible resource that keeps your students active, engaged and thinking mathematically. With movement, decoding, and creativity built in, it’s a refreshing way to practise addition while adding some energy to your day.
