1 CC.1.OA.1 Represent and solve problems involving addition and subtraction. Use addition and subtraction within 2 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. GA.1.N.3 Students will add and subtract numbers less than 1, as well as understand and use GA.1.N.3.h Solve and create word problems involving addition and subtraction to 1 without P a g e 1 Grade Difference CC.1.OA.2 Represent and solve problems involving addition and subtraction. Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 2, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. GA.1.N.3 Students will add and subtract numbers less than 1, as well as understand and use GA.1.N.3.h Solve and create word problems involving addition and subtraction to 1 without CC.1.OA.3 Understand and apply properties of operations and the relationship between addition and subtraction. Apply properties of operations as strategies to add and subtract. Examples: If = 11 is known, then = 11 is also known. (Commutative property of addition.) To add , the second two numbers can be added to make a ten, so = = 12. (Associative property of addition.) (Students need not use formal terms for these properties.) GA.1.N.3 Students will add and subtract numbers less than 1, as well as understand and use GA.2.N.2 Students will build fluency with multi-digit addition and subtraction. GA.2.N.2.d Use basic properties of addition (commutative, associative, and identity) to simplify problems (e.g by taking two from 17 and adding it to the 98 to make 1 and replacing the original problem by the sum ). CC.1.OA.4 Understand and apply properties of operations and the relationship between addition and subtraction. Understand subtraction as an unknown-addend problem. For example, subtract 1 8 by finding the number that makes 1 when added to 8. GA.1.N.3 Students will add and subtract numbers less than 1, as well as understand and use GA.1.N.3.d Understand a variety of situations to which subtraction may apply: taking away from a set, comparing two sets, and determining how many more or how many less.

CC.1.OA.6 Add and subtract within 2. Add and subtract within 2, demonstrating fluency for addition and subtraction within 1. Use strategies such as counting on; making ten (e.g., = = = 14); decomposing a number leading to a ten (e.g., 13 4 = = 1 1 = 9); using the relationship between addition and subtraction (e.g., knowing that = 12, one knows 12 8 = 4); and creating equivalent but easier or known sums (e.g., adding by creating the known equivalent = = 13). GA.1.N.3 Students will add and subtract numbers less than 1, as well as understand and use CC.1.OA.7 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. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 1, = 2 + 5, = CC.1.OA.8 Work with addition and subtraction equations.

3 P a g e 3 CC.1.NBT.2 Understand place value. Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases: -- a. 1 can be thought of as a bundle of ten ones called a ten. -- b.

GA.2.N.2.a Correctly add and subtract two whole numbers up to three digits each with regrouping. GA.2.N.2.c Use mental math strategies such as benchmark numbers to solve problems.

Subtract multiples of 1 in the range 1-9 from multiples of 1 in the range 1-9 (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. GA.1.N.3 Students will add and subtract numbers less than 1, as well as understand and use GA.1.N.3.g Apply addition and subtraction to 2 digit numbers without regrouping (e.g , 8-6, , 1-3, ). GA.1.N.3.h Solve and create word problems involving addition and subtraction to 1 without CC.1.MD.1 Measure lengths indirectly and by iterating length units.

GA.1.M.1.b Estimate and measure using a non-standard unit that is smaller than the object to be measured. CC.1.MD.2 Measure lengths indirectly and by iterating length units. 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. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps. GA.1.M.1 Students will compare and/or order the length, height, weight, or capacity of two or more objects by using direct comparison or a nonstandard unit.

5 P a g e 5 orientation, overall size); for a wide variety of shapes; build and draw shapes to possess defining attributes. GA.1.G.1 Students will study and create various two and three-dimensional figures and identify basic figures (squares, circles, triangles, and rectangles) within them. GA.1.G.1.a Build, draw, name, and describe triangles, rectangles, pentagons, and hexagons. GA.1.G.2 Students will compare, contrast, and/or classify geometric shapes by the common attributes of position, shape, size, number of sides, and number of corners. CC.1.G.2 Reason with shapes and their attributes. Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or threedimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape. (Students do not need to learn formal names such as right rectangular prism. ) GA.1.G.1 Students will study and create various two and three-dimensional figures and identify basic figures (squares, circles, triangles, and rectangles) within them.

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. GA.1.N.4 Students will count collections of up to 1 objects by dividing them into equal parts and represent the results using words, pictures, or diagrams. GA.1.N.4.a Use informal strategies to share objects equally between two to five people.
