What concepts are covered

The following table lists the concept numbers and names used by the 5-A-Day Online service.  Most concepts also have selectable difficulty levels and may include options of how the concept is presented, so this list should serve as a general reference.  The numbering comes from the Math on the Level Concept Chart, which is the reference for the four teaching guides: Operations, Geometry and Measurements, Money and Decimals, and Fractions.  Any breaks or missing numbers (such as 1-4) identify concepts in the curriculum that do not have 5-A-Day problems, either because the number identifies a reference page or else a very early concept which gets practiced verbally or through activities.
