Calculator Assistance

In NYS the 6th grade does not use any type of calculator.  However, when the students enter 7th grade the scientific calculator is introduced.  They are not allowed to use the scientific calculator on part I of their tests (multpile choice), but they are allowed to use it on part II of their tests (short answer and extended response).  Therefore, the 7th grade math teachers are responsible for teaching the kids how to use the scientific calculator.  As part of our supply list we require the kid to purchase  the scientific calculator: Texas Instruments TI-30 II S  as displayed below.  Underneath the picture there are some links to podcasts of myself that explain how to perform certain operations using this calculator.
