The Fraction Unit involves the use of fractions to describe equal parts of a whole in order to answer questions such as:
Grade 2
Place Value Unit
The Place Value Unit involves understanding the relative position, magnitude and relationships within the numeration system in order to answer questions such as:
- How could you use base-10 blocks to show what the numerals in this number mean?
- How can you use the additive property of place value to decompose this number?
- What other way(s) can you use thousands, hundreds, tens, and ones to show this number without changing its value?

2.G.A.3
Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.
