Abstract:

Using the CCRS's multiple references to the number line, this numeracy session uses the number line as the focus of "Coherence" from the beginning, definition of number sets through Algebraic thinking.  We investigate the age-old question, "Why is a negative times a negative a positive?"  We explore basic operations (add, subtract, multiply and divide) and continue on to solve simple algebraic equations.
