## Description

- Overview:
- The intent of clarifying statements is to provide additional guidance for educators to communicate the intent of the standard to support the future development of curricular resources and assessments aligned to the 2021 math standards. Clarifying statements can be in the form of succinct sentences or paragraphs that attend to one of four types of clarifications: (1) Student Experiences; (2) Examples; (3) Boundaries; and (4) Connection to Math Practices.

## Standards

Learning Domain: Geometry

Standard: Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes. (Sizes are compared directly or visually, not compared by measuring.)

Degree of Alignment: Not Rated (0 users)

Learning Domain: Geometry

Standard: Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.

Degree of Alignment: Not Rated (0 users)

Learning Domain: Geometry

Standard: Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.

Degree of Alignment: Not Rated (0 users)

Learning Domain: Measurement and Data

Standard: Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.

Degree of Alignment: Not Rated (0 users)

Learning Domain: Measurement and Data

Standard: Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen.

Degree of Alignment: Not Rated (0 users)

Learning Domain: Measurement and Data

Standard: Estimate lengths using units of inches, feet, centimeters, and meters.

Degree of Alignment: Not Rated (0 users)

Learning Domain: Measurement and Data

Standard: Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit.

Degree of Alignment: Not Rated (0 users)

Learning Domain: Measurement and Data

Standard: Use addition and subtraction within 100 to solve word problems involving lengths that are given in the same units, e.g., by using drawings (such as drawings of rulers) and equations with a symbol for the unknown number to represent the problem.

Degree of Alignment: Not Rated (0 users)

Learning Domain: Measurement and Data

Standard: Represent whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, _ , and represent whole-number sums and differences within 100 on a number line diagram.

Learning Domain: Measurement and Data

Standard: Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.

Degree of Alignment: Not Rated (0 users)

Learning Domain: Measurement and Data

Standard: Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ (dollars) and ĺ˘ (cents) symbols appropriately. Example: If you have 2 dimes and 3 pennies, how many cents do you have?
