What Calculator Does My Child Need?

Shopping for a calculator can be tough. What should your child use and when should they graduate to a scientific calculator? Here are some answers for those questions:

Abacus to learn adding and subtracting

Grade 1 to Grade 3

Children should not be using calculators at this age. At this stage they are still learning to add and subtract. They are visual or physical learners – they want to be able to see and touch what they are counting and adding or taking away from. At this age, having a bag of beans or counters and maybe even an abacus is a good idea. This is a great way to see what is happening when you add beans together (you get more) or when you take beans away (you get less). They can even begin the basics of division and multiplication using beans (marbles, jelly tots and so on).

Grade 4 and 5

Students in grade 4 and 5 can use the SHARP EL231. A simple calculator with all the important keys – square root, plus or minus sign and percentage button (Great for parents too).

Grade 6 to Grade 9

For learning calculator skills with a scientific calculator SHARP has two great options for students. The first is the SHARP EL-531WHB scientific calculator. This scientific calculator has two modes – Normal and Statistics. It also has direct algebraic logic (DAL) meaning that it follows the rules of BODMAS. There is a fraction key, percentage key and a random function. You can even convert numbers between the binary, hexadecimal, decimal, octal and pentadecimal systems. The statistics mode is easy to use as all statistics functions, for example, the average and standard deviation, can be calculated by just pushing two keys. This calculator is very simple and easy to use.

The second alternative is the more advanced SHARP EL-W535HT scientific calculator. This calculator has 4 different modes: – Normal, Statistics, Drill and Table. Normal mode has new features such as the D1 – D4 keys which are short-cut keys. It has a Write View screen, which means that you can type any calculation into the calculator as you see it in the textbook. It also has a random function, an easy to use percentage key, and a shortcut to find the hypotenuse of a right angled triangle. Statistics mode is as easy to use as the EL-531WHB – quick and easy. Drill mode allows the student to practice their basic maths calculations. There are two options in Drill mode: Math and Table. Math practices either addition, subtraction, multiplication, division or all four operations in one set of questions. You can also choose between 25, 50 or 100 questions. Table mode practices a particular set of times tables in either serial order or randomly mixed. The calculator will mark each question and will give a total at the end of the question set as well the percentage of answers correct. Finally, Table mode allows the learner to put in an equation and the calculator gives back coordinate pairs which allows the student to draw a graph. Table mode can also be used to find factor pairs. Because the table is unlimited students are able to access a wider range of values on the graph.

Grade 10 to 12 Mathematics

Grade 10 to 12 students can also use the SHARP EL-W535HT calculator. Some extra features include an easy to use log button, permutations, combinations and factorial buttons. The asymptote in table mode is displayed as a dotted line (——-) so that students are not confused about what it is. Data stored in the statistics mode remains saved in the statistics mode so that students can access it at a later stage. All previous calculations are also stored so that if the calculator is switched off and then on again the calculation will still be on the screen. Previous calculations can be accessed by pressing the up arrow key.

Another great calculator for mathematics students and advanced maths students is the SHARP EL-506WB scientific calculator. It has 6 different modes: Normal, Statistics, Drill, Complex, Matrix, List and Equation. Normal, Statistics and Drill are the same modes as in the SHARP EL-W535HT calculator, with the exception that in normal mode you can now also differentiate at a point, integrate over an interval, find the sum of of a series, do conversions and use constants. Complex mode allows calculations with complex numbers using either rectangular or polar coordinates. Matrix mode allows calculations involving matrices, and using the MATH key to find the determinant or to transpose the matrix. List mode allows storage of a list of numbers (such as vectors) and calculations using these lists. Finally, Equation mode allows the input of either two two-variable or three variable equations to solve simultaneously, or to put in a quadratic or cubic equation and solve for their roots.

Students studying further in Accounting

SHARP also has a wonderful financial calculator that is intuitively easy to use. The SHARP EL-738 financial calculator has two modes: Normal and Statistics. In normal mode financial calculations, normal calculations and scientific calculations can be done. The statistics mode also follows the same easy to use functionality of the other scientific calculators.
