This class is aligned to the Common Core Standards for 2nd grade mathematics. The course focuses on four critical areas. First, the students will extend their understanding of base-ten notation. This includes the idea of counting in fives and tens. Students should understand multi-digit numbers by understanding that the digits in each place represent amounts of thousands, hundreds, tens, or ones. Second, the students will become proficient in addition and subtraction. They will now be able to add and subtract numbers up to 1000 by applying their understanding of addition and subtraction.
