Education
This is one of a set of resources developed to support the teaching of the primary national curriculum. They are designed to support the delivery of key topics within maths and science. This resource focuses on solving addition- and subtraction- based numeracy problems to find the code that will open a safe door.
Do you have the maths knowledge to ‘crack the code’ and open the safe?!
In this activity learners will solve three addition and subtraction problems. The answer to each problem will give two out of the six digits needed to crack the code to a safe. They will reinforce their addition and subtraction knowledge and apply this in a fun context.
This activity could be used as a starter activity covering learning from the previous lesson, a plenary activity reinforcing learning that has just taken place, or as one of several activities within a wider scheme of learning focusing on addition and subtraction.
The activity sheet includes teachers' notes, useful web links, and links (where appropriate) to the national curriculum in each of the four devolved nations; England, Northern Ireland, Scotland and Wales.
All activity sheets and supporting resources are free to download, and all the documents are fully editable, so you can tailor them to your students' and your schools' needs.
