This week’s recommendation comes from:
Kristin Klingensmith
Mathematics Fellow
Kristin says, “I love engaging with young learners as they start to discover that quantities are made up of other quantities, which is significant for understanding the part-whole relationship and the operations of addition and subtraction. Check out this video of Graham Fletcher narrating and representing the progression of understanding for addition and subtraction.”
The Progression of Addition and Subtraction
Graham Fletcher
“The context should always drive the strategy the students are using.” – Graham Fletcher, math specialist
Math specialist and former teacher Graham Fletcher takes us through the progression of addition and subtraction from kindergarten to fourth grade. Graham breaks the concepts down into foundational ideas and illustrates the progression in informative ways using a variety of mathematical representations.
