A series of crack the code questions including; addition, subtraction, more than , less than, halving, quartering. 2 digit add/subtract 1 digit. 2 digit add/subtract 2 digit.
The resource looks good but I am unclear what code the children have to crack? If you could clarify, I'd be happy to edit my review
