Operations and Algebraic Thinking
Fact Fluecy
(September  October) 
 Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20.
 Apply properties of operations as strategies to add and subtract. (Commutative and Associative Properties)
 Understand subtraction as an unknownaddend problem.
 Relate counting to addition and subtraction.
 Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.
 Use strategies such as counting on; making ten, decomposing a number leading to a ten,using the relationship between addition and subtraction, and creating equivalent but easier or known sums.
 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.
 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.

Number and Operations in Base Ten
Place Value
Part 1
(November  December) 
 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 that the two digits of a 2 digit number represent amounts of tens and ones.
 Compare two twodigit numbers based on meanings of tens and ones digits, recording the results of comparisons with the symbols >, =, <.
 Given a 2 digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.
 Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions.

Number and Operations in Base 10
Addtion and Subtraction
Part 2
(January  February) 
 Add within 100, including adding a twodigit number and a onedigit number, and adding a twodigit 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; relate the strategy to a written method and explain the reasoning used.
 Understand that in adding twodigit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.
 Given a twodigit 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 1090 from multiples of 10 in the range 1090 (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; relate the strategy to a written method and explain the reasoning used.

Geometry
(April) 
 Distinguish between defining attributes versus nondefining attributes, build, and draw shapes to possess defining attributes.
 Compose twodimensional shapes or threedimensional shapes to create a composite shape, and compose new shapes from the composite shape.
 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.
 Understand for these examples that decomposing into more equal shares creates smaller shares.
 Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.
 Use strategies such as counting on; making ten, decomposing a number leading to a ten, using the relationship between addition and subtraction, and creating equivalent but easier or known sums.
 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.

Measurement
(May  June) 
 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 samesize length units that span it with no gaps or overlaps.
 Tell and write time in hours and halfhours using analog and digital clocks.
 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.
