KNS.1.0:
Students understand the relationship between numbers and quantities (i.e., that a set of objects has the same number of objects in different situations regardless of its position or arrangement).
KNS.1.1: Compare two or more sets of objects (up to ten objects in each group) and identify which set is equal to, more than, or less than the other.

KNS.1.3 Know that the larger numbers describe sets with more objects in them than the smaller numbers have.
KNS.2.0:
Students understand and describe simple additions and subtractions.
KNS.2.1 Use concrete objects to determine the answers to addition and subtraction problems (for two numbers that are each less than 10).
KNS.3.0:
Students use estimation strategies in computation and problem solving that involve numbers that use the ones and tens places.
KNS.3.1 Recognize when an estimate is reasonable.
