This number sense is based off of the VA Standards, but can be used for anyone. You only need a few basic materials to give the assessment (pencil, paper, manipulatives for counting, numeral flash cards). There are multiple versions. There is one with directions and results on same page or you can use the version with directions and results on separate pages. There are versions for one time use, and versions for use up to three times (pre and post, or beg, mid, end of year). It's very helpful to pinpoint those weak areas for Kindergarten number sense.
