Your students can have fun practising their three-digit algorithm subtraction with these code breaker worksheets.

Three differentiated versions of the worksheet are available. The first does not require regrouping, the second needs some regrouping and the third mostly requires regrouping.

After completing the calculations, your students will use their answers and the code to reveal a secret item. The item will be an attraction or amenity for their world of adventure. A recording and planning sheet are provided for your students to create their world.

The more worksheets that your students complete, the more attractions or amenities they will collect for their world of adventure. This will encourage your students to learn the next maths skills.
