These notes cover everything covered in the grade 10 section of Measurement for CAPS, including revision of grade 9 work (perimeter and area) and surface area and volume of 3D shapes. The Measurement notes also include practice exercises so that students can follow their learning with practice. The answer sheet is also available separately. Measurement […]

Factorising is hard sometimes – particularly if you cant remember the factors for a certain number. Here is a trick to help you. First put the calculator in Table mode by pressing Then press the button. At the top of the fraction put the number you are trying to factorise in. Next press the key […]
This is really easy! If you have the x and y coordinates: For example: (3; 4) Type in 3 4 Your calculator screen will then look like this: r is your hypotenuse – which is 5 and your angle made with between the y-axis and the hypotenuse is 53o What if you have the angle and […]
Second Common Differences can be a bit complicated. The SHARP EL-535 can be very useful to help you figure out the formula and also to check whether your answers are right. Let’s do an example: You are given the pattern 3, 7, 15… On your calculator press: 1 (For stat) and then 2 for Quad […]
In normal mode, the SHARP EL535 has a random function. If you press to access the random menu, you will find that you have 4 options: 0:RAND 1:R-DICE 2:R-COIN 3:R-INT RAND gives random numbers between 0 and 1 to three decimal places. R-DICE gives the numbers 1 to 6 (just […]
Enter the Quadratic Function using your Memory Keys For example: 0 = 2×2 + 5x – 6 Make sure you are in Normal mode by pressing 0. We know that a = 2; b = 5 and c = -6. We need to store this in the calculator. So we press 2 . Now store b so type […]
To prove the CAST Diagram On your SHARP EL535 calculator press . Then type in . For X_Start: type in 90 and . For X_Step: type in 15 and . Look at the answers between -90 and 0 – are they all positive or all negative? They are all negative: therefore sin is negative between […]
Binary numbers are based on the concept of ones and zeros or something similar to on and off. The base used to count in binary number is 2 and the one and zero says whether that 2 is on or off. The position of the one or zero in the binary number tells you to […]
This worksheet looks at the Geometry of 2D shapes in the grade 8 CAPS document (topic 3.1). It includes classifying 2D shapes – both triangles and quadrilaterals; similarity and congruency and solving problems questions.
