N.11. Kindergarten Curriculum Focal Points
11.1. Number and Operation: Representing, comparing, and ordering whole numbers and joining and separating sets
11.1.1. Children use numbers, including written numerals, to represent quantities and to solve quantitative problems, such as counting objects in a set, creating a set with a given number of objects, comparing and ordering sets or numerals by using both cardinal and ordinal meanings, and modeling simple joining and separating situations with objects. They choose, combine, and apply effective strategies for answering quantitative questions, including quickly recognizing the number in a small set, counting and producing sets of given sizes, counting the number in combined sets, and counting backward.
11.3. Measurement: Ordering objects by measurable attributes
11.3.1. Children use measurable attributes, such as length or weight, to solve problems by comparing and ordering objects. They compare the lengths of two objects both directly (by comparing them with each other) and indirectly (by comparing both with a third object), and they order several objects according to length.
2.1. Understand patterns, relations, and functions.
2.1.1. Sort, classify, and order objects by size, number, and other properties.
4.1. Understand measurable attributes of objects and the units, systems, and processes of measurement.
4.1.1. Recognize the attributes of length, volume, weight, area, and time.
4.1.2. Compare and order objects according to these attributes.
4.1.3. Understand how to measure using nonstandard and standard units.
4.1.4. Select an appropriate unit and tool for the attribute being measured.
4.2. Apply appropriate techniques, tools, and formulas to determine measurements.
4.2.3. Use tools to measure.
