We’ve spoken to lots of teachers and mathematicians about the finer points of studying A-level maths. One of the things we’ve learned is that students benefit greatly from having a range of options to explore the challenging topics they will encounter in years 12 and 13.

The Casio fx-991 CW is the most advanced handset in our scientific calculator range and the minimum requirement for studying A-level maths. But, with discrete distribution, where it might not be able to take the exact value you want to get that probability, the fact that it’s not continuous makes it harder because you’re not going to get the exact probability. The calculator helps here by finding the best probability between limits for students, and students can decide how to interpret that. Let’s take statistics as an example. The range of functionality available on graphic calculators includes the option to calculate probability distributions and graph the results.Casio offers free, one-hour training sessions led by experts, which put the power of this calculator into context with A-level question demonstrations. This allows students to see a clear representation of the values across the graph so they can find the sum of the figures and complete other calculations with greater speed and efficiency. Students will need access to at least trigonometric functions. The minimum-requirement scientific calculator is the fx-83G CW or fx-85GT CW. These have all the functionality required for GCSE. However the advanced scientific calculator fx-991CW will give students an advantage for both learning and the exam in solving equations. Please see our model comparison to evaluate these calculators. When students have the capability to easily plot and analyse graphs, it opens up a world of possibilities to visualise mathematical problems in different ways. As well as contributing to stronger understanding, this can prompt discussion and encourage learners to experiment with different values and parameters in graphs.

They can always find one solution by working through the equation algebraically, but this might not be enough to get full marks. By graphing the equation on a calculator, they can instantly see how many points of intersection exist. What’s more, they can feel confident that the graph they’re looking at is accurate, which isn’t always the case when drawing by hand. Greater power to explore challenging topics Ask any teacher, and they’ll likely agree: displaying probability distributions has typically been a challenge on many graphing calculators. Fortunately, that’s all changing. With the new Distribution App on the fx-CG50, it’s now possible to visualise both discrete and continuous distributions with a graph. We spoke with experienced Maths Education Consultant Gerard Dummett to learn more about this big leap forward. How the Distribution App enhances probability visualisation
