Use addition and subtraction within 20 to solve word problems with unknowns in all positions (e.g., by using objects, drawings, and/or equations with a symbol for the unknown number to represent the problem).

Compose two-dimensional shapes or three-dimensional shapes to create a composite shape.

Understand that the two digits of a two-digit number represent groups of tens and ones. Understand the following as special cases: a. 10 can be thought of as a group of ten ones — called a “ten”. b. The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones. c. The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight, or nine tens (and 0 ones).

Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20 (e.g., by using objects, drawings, and/or equations with a symbol for the unknown number to represent the problem).

Count to 120 by 1's, 2's, and 10's starting at any number less than 100. In this range, read and write numerals and represent a number of objects with a written numeral.

Arizona has fully implemented the Arizona College and Career Ready Standards (ACCRS)

Arizona has fully implemented the Arizona College and Career Ready Standards (ACCRS). Arizona schools will administer the AzMERIT assessments to measure student proficiency of Arizona’s College and Career Ready Standards. Education Galaxy’s AzMERIT test preparation program provides online assessment and practice for students in Grades k-5 to help build mastery towards the ACCRS Standards. Our unique online program is easy to use and enjoyable for both teachers and students. Students work on their Study Plans practicing important concepts while teachers pull formative assessment reports to identify the strengths and weaknesses of their classroom and individual students.
