 2.OA.2  Fluently add and subtract within 20 using mental strategies.

By end of grade 2, know from memory all sums of two one-digit numbers. 
Use place value understanding and properties of operations to add and subtract.
 2.NBT.5  Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.


Understand place value. 
2.NBT.1  Understand that the three digits of a three-digit number represent amounts of hundreds, tens and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases:  a. 100 can be thought of as a bundle of ten tens – called a “hundred.” b. The numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to one, two, three, four, five, six, seven, eight, or nine hundreds (and 0 tens and 0 ones). 
2.NBT.2  Count within 1000; skip-count by 5s42, 10s, and 100s. 
 2.NBT.3  Read and write numbers to 1000 using base-ten numerals, number names, and expanded form. 
2.NBT.4  Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons
