Common Core Standards covered by this resource:
✔K.CC.A.1 Count to 100 by ones and by tens.
✔K.CC.B.4 Understand the relationship between numbers and quantities; connect counting to cardinality.
✔K.CC.B.4a 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.B.4b 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.B.4c Understand that each successive number name refers to a quantity that is one larger.
✔K.CC.B.5 Count to answer "how many?" questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1-20, count out that many objects.
✔K.CC.A.2 Count forward beginning from a given number within the known sequence (instead of having to begin at 1).
✔1.OA.C.5 Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
✔1.OA.C.6 Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
