TN.2.NBT. Number and Operations in Base Ten (NBT)
2.NBT.A. Understand place value.
2.NBT.A.1. Know that the three digits of a three-digit number represent amounts of hundreds, tens, and ones (e.g., 706 can be represented in multiple ways as 7 hundreds, 0 tens, and 6 ones; 706 ones; or 70 tens and 6 ones).
2.NBT.A.2. Count within 1000. Skip-count within 1000 by 5s, 10s, and 100s, starting from any number in its skip counting sequence.
2.NBT.A.3. Read and write numbers to 1000 using standard form, word form, and expanded form.
2.NBT.A.4. Compare two three-digit numbers based on the meanings of the digits in each place and use the symbols >, =, and < to show the relationship.
2.NBT.B. Use place value understanding and properties of operations to add and subtract.
2.NBT.B.5. Fluently add and subtract within 100 using properties of operations, strategies based on place value, and/or the relationship between addition and subtraction.
2.NBT.B.6. Add up to four two-digit numbers using properties of operations and strategies based on place value.
2.NBT.B.7. Add and subtract within 1000 using concrete models, drawings, strategies based on place value, properties of operations, and/or the relationship between addition and subtraction to explain the reasoning used.
2.NBT.B.9. Explain why addition and subtraction strategies work using properties of operations and place value. (Explanations may include words, drawing, or objects.)
TN.2.G. Geometry (G)
2.G.A. Reason about shapes and their attributes.
2.G.A.3. Partition circles and rectangles into two, three, and four equal shares, describe the shares using the words halves, thirds, fourths, half of, a third of, and a fourth of, and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.
