It uses three digit numbers with regrouping and has problems involving two-step and unknowns. I use this one of two ways with my class. The first way is I put the color version on the overhead and solve together or on white boards.
The other way we used this was I let the class work in groups. I gave each group a black and white version to glue to the top of a piece of construction paper. They solved and checked their work. Then I had them come to the projector and explain to the class how they got their answer and how they checked it.
It includes 8 word problems in color and black and white. Click on any of the pictures to grab this freebie.
