It has been brought to my attention that the calculators (the Casio f(x)- 300 ESPlus) are priced at $50 at the Walmart store here in town. You are able to purchase this online for $10 from Walmart or from Amazon. I have heard that they will not price match to their own website. I apologize for this, however, this calculator is the one I prefer, so that we can all be on the same page as to what buttons to look for on the calculator. It is helpful for them to be using the same calculator. If you would please also, with a sharpie, write your child’s first and last name on the calculator body and the cover, not just the cover. This helps me be able to return a calculator when found in my classroom or another place on campus. Thank you!
