K-12 Geometry Standards for Shape Answer Sheet
K-12 Geometry Standards for Shape – Answer Sheet
Condensed versions of the standards were written on the cards. The complete standard is included in the right column below.
Note that within grade levels, the standards are not necessarily in the order that they will be taught. Pacing guides are being developed. Also, for some standards, prior mastery of another standard in that same grade level is not required. The progression you developed should at least follow grade levels.
