Bring energy and excitement to multiplication with our Mathsercise Coding: Three-Digit by One-Digit Multiplication Worksheets! This resource combines formal algorithm practise with coding fun and movement-based challenges that will keep students motivated and engaged.

Students begin by solving a series of three-digit by one-digit multiplication problems using the vertical algorithm. Once they’ve completed their calculations, they use the code key to reveal a mystery fitness activity - think jumping jacks, high knees, or frog hops! This kinaesthetic element helps reinforce problem-solving accuracy and builds enthusiasm for maths lessons.

Next comes the creative twist! Students are given space to create their own coded multiplication challenges. They write a new set of problems and use the code key to link their answers to a different secret exercise. Then, they swap with a partner, decode the new challenge, and perform the mystery movement. This peer exchange makes learning collaborative, memorable and fun!

Key Learning Outcomes:

• ✅ Apply the written algorithm to multiply three-digit by one-digit numbers
• ✅ Strengthen understanding of place value and regrouping concepts
• ✅ Decode numeric values into coded messages using logic and reasoning
• ✅ Build fluency in multiplication through structured and creative tasks
• ✅ Enhance engagement by incorporating movement into maths practice

What’s Included:

• 3 differentiated worksheet versions:
  • - Version 1: No regrouping required
  • - Version 2: Some regrouping required
  • - Version 3: All regrouping required
• Movement coding key
• Template for students to write and encode their own multiplication challenges
• Clear instructions for teachers and students

Materials Needed:

• Printed worksheets (one per student or pair)
• Pencils or pens
• Clipboards (optional for outdoor use)
• No equipment required for movement tasks

How to Use:

1. Select the appropriate worksheet version for your students or use all three as a progression.
2. Students solve each multiplication problem using the algorithm.
3. They use the code key to reveal a secret exercise linked to their answers.
4. Students perform the movement, then create their own coded activity to share.
5. Partners swap challenges, solve the problems, decode, and complete the movement.

Ideas for Classroom Use:

• 💡 Use as part of maths rotations for a fun fluency station
• 💡 Add to your Friday maths fun folder or fast-finisher activities
• 💡 Take the activity outside for a brain and body break during maths sessions
• 💡 Use as a creative assessment to check algorithm accuracy in an engaging way
• 💡 Incorporate into a health and maths integrated lesson

Top Teacher Tips:

• 💛 Let students choose or vote on class movement codes to personalise the activity
• 💛 Support students with visuals or manipulatives to scaffold the algorithm process
• 💛 Encourage students to use coloured pencils to distinguish each step of their working out
• 💛 Display decoded exercises on a class challenge board for ongoing use

Mathsercise Coding: Three-Digit by One-Digit Multiplication Worksheets are the perfect blend of maths rigour, coding curiosity, and movement fun - designed to energise your classroom and build confidence with multiplication strategies!
