I just completed my Counting Money Madness packet. It has many money word problems which are aligned with the Common Core Standard 2.MD.8–solving word problems involving dollar bills, quarters, dimes, nickels, and pennies. This math resource also includes 4 sets of money task cards which are great to use in centers.
You can get some free sample pages of counting money at the end of this post.
Here is a FREE counting coins worksheet and money word problems for second grade.
