Math Continuum: Addition and Subtraction - Session 3

The session, Math Continuum: Addition and Subtraction - Session 3, was presented online on Tuesday, November 19th.  This online session was presented by Heather Wark (Lakehead University), Alicia Schenck and Samantha Vanhooft (LKDSB).  

The continua referenced are:

- Addition and Subtraction Continuum by Dr. Alex Lawson, Lakehead University

Children should learn their number facts. However, they would benefit from learning these facts by using an increasingly sophisticated series of strategies rather than by jumping directly to memorization.
- (Lawson, 2016, p. 4)

Strategies help students find an answer even if they forget what was memorized. Discussing math fact strategies focuses attention on number sense, operations, patterns, properties, and other critical number concepts.
- (O’Connell & SanGiovanni, 2011, p. 5)

Strategies include:
- Splitting
- Getting to a decade # 
- Taking jumps of 10 forward/backward

- Using overshoot & return
