OK.2.1. Algebraic Reasoning: Patterns and Relationships - The student will use a variety of problem-solving approaches to model, describe and extend patterns.
2.1.2. Formulate and record generalizations about number patterns in a variety of situations (e.g., addition and subtraction patterns, even and odd numbers, build a table showing the cost of one pencil at 10 cents, 2 pencils at 20 cents).
2.1.3. Find unknown values in open number sentences with a missing addend and use to solve everyday problems.
2.1.4. Recognize and apply the associative property of addition (e.g., 3 + (2 +1) = (3 + 2) + 1).
OK.2.2. Number Sense and Operation - The student will use numbers and number relationships to acquire basic facts and will compute with whole numbers less than 100.
2.2.1. Number Sense
2.2.1.a. Use concrete models of hundreds, tens, and ones to develop the concepts of place value and link the concepts to the reading and writing of numbers (e.g., base-10 blocks).
2.2.1.b. Represent a number in a variety of ways (e.g., write 15 as 8 + 7, write 25 as 2 tens + 5 ones or as 1 ten + 15 ones).
2.2.1.c. Write a number sentence to compare numbers less than 1,000 (e.g., 425 > 276, 73 < 107, page 351 comes after 350, 753 is between 700 and 800).
2.2.1.d. Demonstrate (using concrete objects, pictures, and numerical symbols) fractional parts including halves, thirds, fourths and common percents (25%, 50%, 75%, and 100%).
2.2.2. Number Operations
2.2.2.a. Demonstrate fluency (i.e., memorize and apply) with basic addition facts to make a maximum sum of 18 and the associated subtraction facts (e.g., 15+3=18 and 18-3=15).
2.2.2.b. Use strategies to estimation and solve sums and differences (e.g., compose, decompose and regroup numbers, use knowledge of 10 to estimate quantities and sums .)
2.2.2.c. Solve two-digit addition and subtraction problems with and without regrouping using a variety of techniques.
OK.2.3. Geometry - The student will use geometric properties and relationships to recognize and describe shapes.
2.3.1. Identify symmetric and congruent shapes and figures.
OK.2.4. Measurement - The student will use appropriate units of measure in a variety of situations.
2.4.1. Linear Measurement
2.4.1.a. Measure objects using standard units (e.g., measure length to the nearest foot, inch, and half inch).
2.4.1.b. Select and use appropriate units of measurement in problem solving and everyday situations.
2.4.2.a. Tell time on digital and analog clocks on the quarter-hour.
2.4.3.a. Identify and count money up to a twenty dollar bill.
2.4.3.b. Recognize and write different amounts of money using dollar and cent notation.
OK.2.5. Data Analysis - The student will demonstrate an understanding of data collection, display, and interpretation.
2.5.1. Data Analysis
2.5.b. Summarize and interpret data in charts, bar graphs, and tables.
