These are 12 problems I wrote for 4th graders. I roughly followed the pacing of the enVision math book, but these can also be stand-alone problems. Each problem has 3 different number sets to differentiate learning, as well as an extension problem for extra challenge. The skills they encompass are: 2,3 and 4-digit multiplication with regrouping, arrays, division, multi-step problems, subtraction with regrouping, compare problems. These are ready to print or you can change the name to your students' names to increase engagement.
