This problem solving packet contains three sets of 30 cards each. There is one problem on each card. The sets are differentiated by the difficulty of the numbers used in the problems. Set one contains problems working with numbers 1 – 12. Set two contains problems working with numbers in the teens and twenties. Set 3 contains problems working with numbers 20 and above.
Sets are marked for easy sorting with a symbol in the upper left had corner of the card. They make great task cards or can be used with a document camera for small group or whole class problem solving lessons
Result unknown and change unknown problems are included. These work well with whole group or small group lessons, in math centers or in math stations. Because they are differentiated, they are great for RTI or for challenging higher achievers.
