I wrote these 12 CGI math problems to use with my 5th graders. Each problem has 3 different number sets so you can differentiate, plus an extension problem for further challenge. The skills they encompass are: place value to the millions place, problem solving, elapsed time, 4-digit addition with regrouping, addition with regrouping with 3 addends, division, missing number problems, subtraction and addition with money, compare problems with decimals, 4-digit subtraction with and without regrouping. These are ready to print or you can change the names to your own students' names to increase their engagement. ANSWER KEY IS INCLUDED.
