## Standards

Learning Domain: Operations and Algebraic Thinking

Standard: Demonstrate an understanding of factors and multiples.

Degree of Alignment: Not Rated (0 users)

Learning Domain: Measurement and Data

Standard: Order three objects by length; compare the lengths of two objects indirectly by using a third object.

Degree of Alignment: Not Rated (0 users)

Learning Domain: Number and Operations in Base Ten

Standard: Count to 120, starting at any number less than 120. In this range, read and write numerals and represent a number of objects with a written numeral.

Degree of Alignment: Not Rated (0 users)

Learning Domain: Operations and Algebraic Thinking

Standard: Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).

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: Measurement and Data

Standard: Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and compare problems using information presented in a bar graph.

Degree of Alignment: Not Rated (0 users)

Learning Domain: Number and Operations in Base Ten

Standard: Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons.

Degree of Alignment: Not Rated (0 users)

Learning Domain: Geometry

Standard: Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.

Learning Domain: Number and Operations - Fractions

Standard: Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b. (Grade 3 expectations in this domain are limited to fractions with denominators 2, 3, 4, 6, and 8.)

Learning Domain: Geometry

Standard: Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

Learning Domain: Operations and Algebraic Thinking

Standard: Find all factor pairs for a whole number in the range 1-100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1-100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1-100 is prime or composite.

Cluster: Add and subtract within 21

Standard: Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
