Everyday students need to bring these things to class:
Two mechanical pencils with erasers
A calculator
A spiral notebook used only for math
A folder or 3-ring binder used only for math
Ruler (with both inches and centimeters)
Graph paper

Students in Pre-Algebra Challenge are required to have a scientific calculator.  These can be purchased at Target for approximately $12.  I recommend the Texas Instruments TI-30X IIS, but any scientific calculator is fine.  Students are strongly encouraged to make this investment, but if they are unable to do so, calculators are available for check-out at the Murray library.  Students may wish to invest in graphing calculators, which run approximately $90, but they are not necessary for this course. 

Students in Algebra Challenge are required to have a graphing calculator.  These can be purchased at Target for approximately $100.  I recommend the Texas Instruments TI-84 Plus, but any TI graphing calculator is fine.  Students are strongly encouraged to make this investment, but if they are unable to do so, a limited number of calculators are available for check-out at the Murray library.
