K.CC.2 Count forward beginning from a given number within the known sequence (instead of having to begin at 1). K.CC.3 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.4 Understand the relationship between numbers and quantities; connect counting to cardinality. K.CC.4.a When 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. K.CC.4.b Understand that the last number name said tells the number of objects counted. The number of objects is the same regardless of their arrangement or the order in which they were counted. K.CC.4.c Understand that each successive number name refers to a quantity that is one larger. K.CC.5 Count to tell the number of objects. K.CC.6 Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies.1 Comparing Whole Numbers 2 Comparing Whole Numbers 3 K.CC.7 Compare two numbers between 1 and 10 presented as written numerals. Geometry K.G.1 Describe 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. K.G.2 Correctly name shapes regardless of their orientations or overall size. K.G.3 Identify and describe shapes (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders, and spheres). K.G.4 Analyze, compare, create, and compose shapes. K.G.5

The Fractions portion of the AAA Math website is particularly useful because it provides visual representations and easy-to-understand instructions. You can choose from a selection of topics like basic fractions, adding fractions, comparing fractions, converting fractions, reducing fractions, etc.

Bugs and Numbers makes a bug's life for kids, as they explore math concepts such as matching, counting, sorting, sequencing, addition, subtraction, fractions, money, measurements, and telling time from the perspective of some realistic-looking critters. In three sections of six games each, bugs explore places like a diner, a junkyard, or a circus, and encounter skills in fitting backdrops. For fractions, ants deliver boxes of pizza to a picnic, and kids choose which fraction is represented in each box. Kids learn to count money in an arcade by dropping the correct amount into the machines. They earn bugs by completing each game and can zoom in to watch their bugs in action.
