All of the problems in my multi-grade database of 42,500+ problems are of 4 difficulty levels--level 1 being the simplest and level 4 being the most difficult. These particular problems are ALL of the ones at this level in the various grade 3 standards. They are only for your students who enjoy challenges.
At my school there are only a few who do--and these particular problems were developed for this type of student. Nevertheless, the students in my regular math classes use worksheets that have the problems in difficulty order and I notice that more and more of the students really like to go to the "last problem" to test their own mettle. For this particular grade, this is the full list--along with the solutions (when applicable).
[The problems in All WORKSHEETS and PREVIEWS are printed in difficulty (1 [easy], 2 [not so easy], 3 [proficiency] up to 4 [mastery]) order within a skill. The actual difficulty level appears slightly to the left of the DK box of each problem in a very small font. Also, instructional references appear on worksheets but are optional on quizzes.]
