I wrote these 12 problems for my 4th graders. The pacing roughly follows the enVision math book, but these are also stand-alone problems. Each problem has 3 number sets to help you differentiate instruction, as well as an extension problem for extra challenge. The skills they encompass are: problem solving, multi-step problems, part/part/whole, 2 and 3 digit multiplication with and without zeroes, rounding, estimation, division. These problems are ready to print or you can change the names to your own students' names to increase their engagement. ANSWER KEY IS INCLUDED.
