PK.M 3.a.2 Sort sets of objects by one characteristics, then sort by a different characteristics and explain the sorting rules (e.g., "These are all of the red ones, but these are all of the big ones")
PK.M 3.a.3 Extend sequential patterns and replicate these patterns using different materials or modes (e.g., on being told a pattern, replicating the pattern with manipulatives)
PK.M 4.a Children learn to measure objects by their various attributes (length, height, weight, volume) and to use differences in attributes to make comparisons.
PK.M 4.a.1 Order (or seriate) four or more items by decreasing or increasing a relative attribute when differences are perceptually clear (e.g., arranging a rock collection from the largest to the smallest)
PK.M 4.a.2 Use some appropriate tools to measure different attributes (e.g., choosing a scale for weight and a cup for volume)
PK.M 4.a.3 Use measurement language to describe the attributes of objects (e.g., "This is three-blocks long.")
