The Common Core State Standards for Grade 1 math can be divided into various domains, each with specific standards and related deliverables. Here’s a table outlining these domains, standards, and deliverables:
|Operations and Algebraic Thinking
|Represent and solve problems involving addition and subtraction
|– Use addition and subtraction within 20 to solve word problems
|– Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20
|Understand and apply properties of operations and the relationship between addition and subtraction
|– Apply properties of operations as strategies to add and subtract
|– Understand subtraction as an unknown-addend problem
|Add and subtract within 20
|– Relate counting to addition and subtraction
|– Add and subtract within 20, demonstrating fluency for addition and subtraction within 10
|Work with addition and subtraction equations
|– Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false
|– Determine the unknown whole number in an addition or subtraction equation relating three whole numbers
|Number and Operations in Base Ten
|Extend the counting sequence
|– 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.
|Understand place value
|– Understand that the two digits of a two-digit number represent amounts of tens and ones
|– Compare two two-digit numbers based on meanings of the tens and ones digits, recording the results of comparisons with the symbols >, =, and <.
|Use place value understanding and properties of operations to add and subtract.
|– Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction
|– Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.
|– Subtract multiples of 10 in the range 10-90 from multiples of 10 in the range 10-90 (positive or zero differences), using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction
|Measurement and Data
|Measure lengths indirectly and by iterating length units
|– Order three objects by length; compare the lengths of two objects indirectly by using a third object.
|– Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number
of same-size length units that span it with no gaps or overlaps.
|Tell and write time
|– Tell and write time in hours and half-hours using analog and digital clocks
|Represent and interpret data
|– Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.
|Reason with shapes and their attributes
|– Distinguish between defining attributes versus non-defining attributes. Build and draw shapes to possess defining attributes.
|– Compose two-dimensional shapes or three-dimensional shapes to create a composite shape, and compose new shapes
|– Partition circles and rectangles into two and four equal shares, describe the shares using the words halves, fourths, and quarters, and use the phrases half of, fourth of, and quarter of. Describe the whole as two of, or four of the shares
This table provides an overview of the Common Core framework for Grade 1 math and the expected deliverables for each standard. Note that specific details and additional sub-points may vary depending on the curriculum and resources provided by each state or school district.
