The Operations Series – Addition

Learning objectives

There are two parts to being able to add reliably.  One is mastering addition facts (such as 4 + 3 = 7) and the second is combining addition facts with place value (such as 18 + 14 = 32).  It is also helpful to be able to estimate an answer to make sure their computation is correct.  We will work on all three of these.
