Count forward beginning from any given number within 100 (instead of having to begin at 1). Count backwards beginning from any given number within 20.
Generate resourceWrite numbers from 0 to 20. Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects).
Generate resourceUnderstand the relationship between numbers and quantities; connect counting to cardinality.
Generate resourceWhen counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object. (one-to-one correspondence)
Generate resourceUnderstand that the last number name said tells the number of objects counted. (cardinality) The number of objects is the same regardless of their arrangement or the order in which they were counted.
Generate resourceUnderstand that each successive number name refers to a quantity that is one larger.
Generate resourceWhen counting, answer questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or and as many as 10 things in a scattered configuration.
Generate resourceIdentify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group. Include groups with up to ten objects.
Generate resourceDescribe objects in the environment using names of shapes, and describe the relative positions of these objects using terms such as above, below, beside, in front of, behind, and next to.
Generate resourceIdentify shapes as two-dimensional (lying in a plane, "flat") or three-dimensional ("solid").
Generate resourceAnalyze and compare two- and three-dimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/"corners") and other attributes (e.g., having sides of equal length).
Generate resourceModel shapes in the world by building shapes from components (e.g., sticks and clay balls) and drawing shapes.
Generate resourceDescribe measurable attributes of a single object or objects, such as length, weight, or size.
Generate resourceDirectly compare two objects with a measurable attribute in common, to see which object has "more of"/"less of" the attribute, and describe the difference.
Generate resourceClassify objects into given categories; count the number of objects in each category and sort the categories by count. Limit category counts to be less than or equal to 10.
Generate resourceIdentify a penny and understand that the value is one. Count pennies within 20.
Generate resourceCompose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (e.g., 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
Generate resourceRepresent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations. (Drawings need not show details, but should show the mathematics in the problem.)
Generate resourceSolve addition and subtraction word problems (within 10), involving result unknown problems, put together/take apart total unknown, and put together/take apart addend unknown, e.g., using objects or drawings to represent the problem. (see appendix for K-2 Common Addition and Subtraction Situations)
Generate resourceAdd and subtract within 10, eg., by using objects or drawings to represent the problem.
Generate resourceDecompose 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 (e.g., 5 = 2 + 3 and 5 = 4 + 1).
Generate resourceFor any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation.
Generate resourceIdentify and describe shapes (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders, and spheres).
Generate resourceUnderstand addition as putting together and adding to, and understand subtraction as taking apart and taking from.
Generate resourceName and describe two-dimensional shapes (circles, triangles, squares, and rectangles) using attributes (sides, vertices, square corners).
Generate resourceIdentify and draw two-dimensional shapes (circles, triangles, squares, rectangles, and trapezoid) in a variety of orientations.
Generate resourceIdentify a clock as a tool that measures time of day. Answer questions about time of day and duration of time using both analog and digital clocks (morning, afternoon, evening, minute, hour).
Generate resourceIdentify a calendar as a tool that measures time in days, months, weeks, years. Answer questions about time sequencing (yesterday, today, tomorrow).
Generate resourceCount groups of pennies and groups of dimes by their values (coins not combined).
Generate resourceRecognize objects within 5 (tallies, five frame, fingers, dominoes, dice, and scattered).
Generate resourceIdentify whether the number of objects in one group is greater than, less than, or equal to the objects of another group (up to ten).
Generate resourceIdentify whether a written number is greater than, less than, or equal to another written number (0-10).
Generate resourceDescribe the relative positions of objects using terms such as above, below, beside, in front of, behind, and next to.
Generate resourceStart counting forward from any number up to 100 and count backward from any number within 20.
Generate resourceUnderstand that the last number name said tells the number of objects counted regardless of arrangement or the order in which they were counted (cardinality).
Generate resourceFor any number from 1 to 9, find the number that makes 10 when added to the given number.
Generate resourceRepresent addition and subtraction within ten using objects, fingers, drawings, mental images, or verbal explanations.
Generate resourceDemonstrate understanding that addition is putting together, getting more, or counting on.
Generate resourceDemonstrate understanding that subtraction is taking away, taking apart, or counting back.
