Use 53 + 23 to explain the standard algorithm of addition. a) Explain the regrouping process including the ideas of combining and place value. b) Use math drawings representing the sum as the combination of 53 objects with 28 objects. c) Use bundled objects as the physical representation of the regrouping process d) Use equations (expanded form) to represent symbolically the physical actions of regrouping.
