TULSA PUBLIC SCHOOLS
Mathematics Pacing Calendar
Grade 2

The pacing calendar reflects the quarter in which each objective is to be mastered. More complex concepts may need to be introduced in a previous quarter to ensure mastery.

1st Quarter

Standard 1: Algebraic Reasoning: Patterns and Relationships – The student will use a variety of problem-solving approaches to model, describe and extend patterns.

1.1 Describe, extend, create and take apart patterns using symbols, shapes or designs (e.g., repeating and growing patterns made up of sets of shapes or designs, create patterns by combining different shapes and taking patterns apart).

Standard 2: Number Sense and Operations – The student will use numbers and number relationships to acquire basic facts and will compute with whole numbers less than 100.

2.1a Number Sense: Use concrete models of hundreds, tens, and ones to develop the concepts of place value and link the concepts of the reading and writing of numbers (e.g., base-10 blocks).
2.1b Number Sense: 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).

Standard 4: Measurement – The student will use appropriate units of measure in a variety of situations.

4.1a Linear Measurement: Measure objects using standard units to the nearest foot, inch, and half inch.
4.1b Linear Measurement: Select and use appropriate units of measurement in problem solving and everyday situations.

2nd Quarter

Standard 1: Algebraic Reasoning: Patterns and Relationships – The student will use a variety of problem-solving approaches to model, describe and extend patterns.

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).

Standard 2: Number Sense and Operations – The student will use numbers and number relationships to acquire basic facts and will compute with whole numbers less than 100.

2.1d Number Sense: Demonstrate (using concrete objects, pictures, and numerical symbols) fractional parts including halves, thirds, and fourths and common percents (25%, 50%, 75%, and 100%).
2.2a Number Operations: Demonstrate fluency (i.e., memorize and apply) with basic addition facts to make a maximum sum of 18 and the associated subtraction facts and fact (e.g., 15+3 =18 and 18-3=15).

Standard 3: Geometry: The student will use geometric properties and relationships to recognize and describe shapes.

3.1 Identify symmetric and congruent shapes and figures.

Standard 4: Measurement – The student will use appropriate units of measure in a variety of situations.

4.2a Time: Tell time on digital and analog clocks to the quarter-hour.
4.2b Solve problems involving number of days in a week, month, or year and problems involving weeks in a month and year.

3rd Quarter

Standard 1: Algebraic Reasoning: Patterns and Relationships – The student will use a variety of problem-solving approaches to model, describe and extend patterns.

1.3 Find unknown values in open sentences with a missing addend and use to solve everyday problems.

Standard 2: Number Sense and Operations – The student will use numbers and number relationships to acquire basic facts and will compute with whole numbers less than 100.

2.1c Number Sense: Write a number sentence to compare numbers less than 1000 (e.g., 425 > 276, 73 < 107, page 351 comes after page 350, 753 is between 700 and 800).
2.2b Number Operations: Use strategies to estimate and solve the sums and differences (e.g., compose, decompose and regroup numbers, use knowledge of 10 to estimate quantities and sums [ two numbers less than 10 cannot add up to more than 20 ]).

Standard 3: Geometry: The student will use geometric properties and relationships to recognize and describe shapes.

3.2 Investigate and predict the results of putting together and taking apart two-dimensional shapes.

Standard 5: Data analysis: The student will demonstrate an understanding of data collection, display, and interpretation.

5.1a Collect, sort, organize and display data in charts, bar graphs, and tables (e.g., collect data on teeth lost and display on a chart).

4th Quarter

Standard 1: Algebraic Reasoning: Patterns and Relationships – The student will use a variety of problem-solving approaches to model, describe and extend patterns.

1.4 Recognize and apply the associative property of addition (e.g., 3 + (2 + 1) = (3 + 2) + 1).

Standard 2: Number Sense and Operations – The student will use numbers and number relationships to acquire basic facts and will compute with whole numbers less than 100.

2.2c Number Operations: Solve two-digit addition and subtraction problems with and without regrouping using a variety of techniques.
2.2d Number Operations: Use concrete models to develop understanding of multiplication as repeated addition and division as successive subtraction.

Standard 4: Measurement – The student will use appropriate units of measure in a variety of situations.

4.3a Money: Identify and count money up to a twenty dollar bill.
4.3b Money: Recognize and write different amounts of money using dollar and cent notation.

Standard 5: Data analysis: The student will demonstrate an understanding of data collection, display, and interpretation.

5.1b Summarize and interpret data in charts, bar graphs, and tables.
