About this deal

Of course, graphing software is an extremely useful teaching and learning tool, but Desmos is free and much more intuitive to use than a graphical calculator, and Autograph, also available free, is a very powerful alternative, so in my opinion there’s really no need for a graphical calculator. So what do I need to know about these new CW calculators? Another one that’s been brought to my attention: the functionality of the button has been changed so that it no longer “attaches” itself to the preceding number. It’s not actually wrong but it’s a change that will be very confusing for many students! The A-level model now has the generic equation solver function in the same place as the quadratic and simultaneous equation solvers, rather than in an apparently random position above the CALC button. If you require any further information relating to the Delivery service used, please call us at +44 (0)20 8208 9567. Sept 2023: A fellow Maths tutor on Facebook recently had a meeting with a Casio representative to discuss these new models. We are told that the intention was to make them more like a phone to use (though I find it hard to see much resemblance myself) and that younger children who aren’t already accustomed to a particular scientific calculator layout have adapted well to its use. However, we are talking about 11-year-olds, and I find it hard to imagine that they’ve been using many of the functions needed for Higher GCSE and A-level Maths!

Our nominated carrier is Parcel Force. Deliveries are made Monday – Friday between 9.00am – 6.00pm (excluding Bank Holidays). Remember I mentioned that a graphical calculator is much more complex to operate than a scientific one? The CW models have narrowed that gap considerably – and not in a good way!If you have exams coming up, then this calculator can be used. It is recommended and approved for Key Stages 3 and 4, which includes GCSE, National and Higher, Junior and Leaving. For more information on what calculators are permissible in exams, take a look at my Clueless about Calculators blog post. Finally, a colour warning The Casio fx-83GT CW ClassWiz is the new upgraded version of the Casio fx-83GT X (the UK’s best-selling scientific calculator), containing additional features, to include a high definition display and improved menu navigation. Allowed in every UK exam where a calculator can be used. Recommended and approved for Key Stages 3 & 4 (including GCSE, National and Higher, Junior and Leaving).

As I mentioned previously, lots of functions – too many to list here – now require more key presses than they did before. A particularly annoying one is nCr (to calculate the number of combinations of r items chosen from a set of n – used in binomial expansion and the binomial probability distribution). Previously it was the Shift function above the ÷ key, but now it takes the following series of key presses to get to the same place:Gain a better understanding of mathematical expressions on the display screen, for example; roots and fractions as they appear in your textbooks, this will increase your comprehension because the results are easier to understand and in plain sight.
