## Oklahoma Math Standards - 1st Grade

MathScore aligns to the Oklahoma Math Standards for 1st Grade. The standards appear below along with the MathScore topics that match. If you click on a topic name, you will see sample problems at varying degrees of difficulty that MathScore generated. When students use our program, the difficulty of the problems will automatically adapt based on individual performance, resulting in not only true differentiated instruction, but a challenging game-like experience.

## Algebraic Reasoning

Standard 1 Algebraic Reasoning: Patterns and Relationships - The student will use a variety of problem-solving approaches to model, describe and extend patterns.
1. Describe, extend and create patterns using concrete objects (e.g., sort a bag of objects by attributes and orally communicate the pattern for each grouping). (Requires outside materials )
2. Describe, extend and create patterns with numbers in a variety of situations (e.g., addition charts, skip counting, calendars). (Skip Counting , Patterns: Numbers )
3. Demonstrate number patterns by counting as many as 100 objects by 1’s, 2’s, 5’s and 10’s. (Skip Counting )
4. Recognize and apply the commutative and identity properties of addition using models and manipulatives to develop computational skills (e.g., 2 + 4 = 4 + 2, 3 + 0 = 3). (Commutative Property 1 )

## Number Sense and Operations

Standard 2 Number Sense and Operation - The student will read, write and model numbers and number relationships. The student will use models to construct basic addition and subtraction facts with whole numbers.
1. Number Sense
a. Use concrete models of tens and ones to develop the concept of place value. (Counting Squares )
b. Compare objects by size and quantity (e.g., more than, less than, equal to).
c. Read and write numerals to 100.
d. Manipulate physical models and recognize graphical representation of fractional parts (e.g., halves, thirds, fourths). (Fraction Pictures )
2. Number Operations
a. Develop and apply the concepts of addition and subtraction.
i. Use models to construct addition and subtraction facts with sums up to twenty (e.g., counters, cubes).
ii. Perform addition by joining sets of objects and subtraction by separating and by comparing sets of objects.
iii. Demonstrate fluency (i.e., memorize and apply) with basic addition facts to make a maximum sum of 10 and the associated subtraction facts (e.g., 7+3=10 and 10-3=7). (Fast Addition , Fast Addition Reverse , Fast Subtraction , Mixed Addition and Subtraction )
b. Write addition and subtraction number sentences for problem-solving situations. (Basic Word Problems )
c. Acquire strategies for making computations using tens and ones to solve two- digit addition and subtraction problems without regrouping (e.g., use estimation, number sense to judge reasonableness, counting on, use base-ten blocks). (Basic Addition to 1000 , Basic Subtraction to 1000 )

## Geometry

Standard 3 Geometry - The student will use geometric properties and relationships to recognize and describe shapes.
1. Sort and identify congruent shapes.
2. Identify, name, and describe two-dimensional geometric shapes (including rhombi) and objects in everyday situations (e.g., the face of a round clock is a circle, a desktop is a rectangle). (Geometric Shapes )
3. Identify, name and describe three-dimensional geometric shapes (including cones) and objects in everyday situations (e.g., a can is a cylinder, a basketball is a sphere).
4. Use language to describe relationships of objects in space (e.g., above, below, behind, between).

## Measurement

Standard 4 Measurement - The student will develop and use measurement skills in a variety of situations.
1. Linear Measurement: Measure objects with one-inch tiles and with a standard ruler to the nearest inch.
2. Time
a. Tell time on digital and analog clocks on the hour and half-hour.
b. Develop the concepts of days, weeks, and months using a calendar.
3. Money: Identify and name the value of pennies, dimes, nickels, and quarters.

## Data Analysis

Standard 5 Data Analysis - The student will demonstrate an understanding of data collection and display.
1. Data Analysis
a. Organize, describe, and display data using concrete objects, pictures, or numbers. (Tally and Pictographs )
b. Formulate and solve problems that involve collecting and analyzing data common to children’s lives (e.g., color of shoes, numbers of pets, favorite foods). (Requires outside materials )
