GRAPHING CALCULATOR PURCHASE INFORMATION

Algebra I (and future higher level mathematics courses) requires the use of a TI-83, TI-83+ or TI-84 graphing calculator. Although we have a class set of these available for student use at school, it is imperative that the students have access to one of these calculators at home. These are the calculators that the students will continue to use throughout high school. Below are some guidelines to help with this purchase:

• The only difference in the TI-83, TI-83+ or TI-84 is the amount of memory. Keystrokes are basically the same. Texas Instruments has discontinued the TI-83 but you may be able to purchase one that has been used

• You may be asked if you would prefer a silver edition of these calculators. The silver edition simply adds more memory but at an additional cost (approximately $20). This edition is not necessary for school.
• Do not purchase a higher level calculator such as a TI-86 or TI-89. All instructions are given for the TI-83, TI-83+ or TI-84. The TI-86 and TI-89 are very different and not as user friendly. In this case, more is not necessarily better.
• During the back-to-school sales, these calculators can be found for $85. Many students have reported finding these on e-bay for much less. Pawn shops also carry new graphing calculators at a discount. A few phone calls may save you money.
• We do not place an order from the school for student purchase since the cost at retail stores is less than we can get from our suppliers.
• New calculators come with a proof of purchase. Please save these to turn into the school’s math department. It is not a check to determine if you have purchased the calculator. Texas Instruments offers additional products to schools with a certain number of proofs or purchase.
