the subject more deeply‚ I thought I would find ways to challenge these misconceptions. Key Concepts and Misconceptions of Area When defining area‚ Koshy et al (2000) discuss that it is a two dimensional concept and relies on comparison with a square due to measures of area being in centimetres squared (cm2) or metres squared (m2). Due to the nature of these measurements‚ it is easy to see why children misconstrue these concepts. The National Numeracy Strategy requires that teachers ’identify

Area of a Cube = 6 a 2 | [pic](a is the length of the side of each edge of the cube) In words‚ the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a‚ or a 2 . Since these are all the same‚ you can multiply one of them by six‚ so the surface area of a cube is 6 times one of the sides squared. |Surface Area of a Rectangular Prism = 2ab + 2bc + 2ac

Laws of Exponents Exponents are also called Powers or Indices The exponent of a number says how many times to use the number in a multiplication. In this example: 82 = 8 × 8 = 64 In words: 82 could be called "8 to the second power"‚ "8 to the power 2" or simply "8 squared" . So an Exponent just saves you writing out lots of multiplies! Example: a7 a7 = a × a × a × a × a × a × a = aaaaaaa Notice how I just wrote the letters together to mean multiply? We will do that a lot here. Example: x6 = xxxxxx
