#### CCSS.maths.CONTENT.2.NBT.A.3

:
"Read and write numbers to 1000 using base-ten numerals, number names, and expanded form."

Our Take:Second graders should be learning to represent numbers up to 1000 in a variety of different forms. For example, the student can represent the number 42 using place value terms (4 tens and 2 ones), expanded form (40 + 2), its number word (forty-two), and its standard form (42).

These lesson plans can help students practise this Common Core State Standards skill.
