This unit will give the opportunity for students to review from Kindergarten how to write numbers correctly, count, work with numbers form 0 – 20, add and subtract within 10, and identify attributes.
PA.CCSS.Math.Content.CC.2.1.K.A.1 Count forward beginning from a given number within the known sequence (instead of having to begin at 1). (K.CC.2)
PA.CCSS.Math.Content.CC.2.1.K.A.1 Write numbers from 0 to 20. Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects). (K.CC.3)
PA.CCSS.Math.Content.CC.2.1.K.A.3 Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group. (K.CC.6)
PA.CCSS.Math.Content.CC.2.1.K.A.3 Compare two numbers between 1 and 10 presented as written numerals. (K.CC.7)
PA.CCSS.Math.Content.CC.2.1.K.B.1 Compare and decompose numbers from 11 to 19 into tens and ones and some further ones, e.g. by using objects or drawings, and record each composition or decomposition by a drawing or equation, understanding that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, nine ones. (K.NBT.1)
PA.CCSS.Math.Content.CC.2.2.K.A.1 Represent addition and subtraction with objects, fingers, mental images, drawings, sounds, acting out situations, verbal explanations, expressions, or equations. (K.OA.1)
PA.CCSS.Math.Content.CC.2.2.K.A.1 Solve addition and subtraction word problems, and add and subtract within 10.1 (K.OA.2)
PA.CCSS.Math.Content.CC.2.2.K.A.1 Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation. (K.OA.3)
PA.CCSS.Math.Content.CC.2.3.K.A.1 Describe objects in the environment using names of shapes, and describe the relative positions of these objects using terms. (K.G.1)
PA.CCSS.Math.Content.CC.2.3.K.A.1 Correctly name shapes regardless of their orientations or overall size. (K.G.2)
PA.CCSS.Math.Content.CC.2.3.K.A.1 Analyze and compare two- and three-dimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, and other attributes. (K.G.4)
