In this unit pupils will identify the addends and the sum in column addition. They will use their knowledge of place value to correctly lay out column addition. In the future unit pupils will identify the minuend and the subtrahend in column subtraction and explain the column subtraction algorithm. They will subtract from a 2-digit number using column subtraction with exchanging.

In the prior unit pupils accurately and efficiently solved multi-step addition and subtraction problems. They understood and explained how both addition and subtraction equations could be used to describe the same additive relationship. In this unit pupils will identify the addends and the sum in column addition. They will use their knowledge of place value to correctly lay out column addition.
