Children love making and breaking codes. Use our website to create your own transpositional (ie. the letters of the alphabet are switched around) and numerical (every letter is a number) code worksheets. You can either enter messages for the children to decode, or get the children to write coded messages for themselves. All of the codes are automatically generated for you - just enter the information you want and press go!
