Know Number Names And The Count Sequence.
Count to 100 by ones and by tens.
K.CC.3:
Counting And Cardinality
Know Number Names And The Count Sequence.
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.OA.1:

Read and write numbers to 1000 using base-ten numerals, number names, and expanded form.
2.NBT.5:
Number And Operations In Base Ten
Use Place Value Understanding And Properties Of Operations To Add And Subtract.
Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
1.OA.3:
Operations And Algebraic Thinking
Understand And Apply Properties Of Operations And The Relationship Between Addition And Subtraction.
Apply properties of operations as strategies to add and subtract.3 Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
