Foundation Calculator Key Topic List and Clues This is only a prediction and should not be used as an exhaustive list * Are the key topics to look at REVISION OVER HALF TERM 1st June at 12:30pm – 3:30pm 2nd June at 12:30pm – 3:30pm HANDLING DATA * Mean/Median/Mode/Range * Scatter Graphs – draw line of best fit. Remember relationship means a sentence Stem and Leaf – watch the key 2 Way Tables – try and spot these questions Frequency Polygon – draw bar chart then join crosses up in the middle Taking a sample – remember need a good number of responses/different venues/different times etc Pictogram NUMBER * Percentages with a calculator * Exchange Rates Prime Numbers – only factor itself and 1 e.g. 2,3,5,7,11,13,17 Cube Numbers – 1,8,27,64,125 Square Numbers – 1,4,9,16,25,36,49,64,81,100 Output and Input Machines Fractions of an amount – divide by the bottom and times by the top * Ratio inc recipe questions Estimation – watch out for this key word Estimation of heights – e.g. a man is 6ft, a bus is 3 x bigger so 18ft * Best Buys – scale up so that they are both the same amount * Electric Bills – difference is the key here ALGEBRA * Trial and Improvement Substitution – plug the values in. Know the difference between (4x)2 and 4x2 Simplifying – e.g. 3 x c x d= 3cd or 5d + 3e – 2d + 4e = 3d + 7e Coordinates – no silly mistakes Solving equations – look for word solve – remember whatever you do to one side you must do to the other * Inequalities – drawing inequalities/ listing integer solutions /writing inequalities/ solving (use same rules as solving equations) Expanding brackets – 4x(x + 7) / 3(x +4) - 4(x – 2) (watch double negative) * Drawing graphs – You must know the graphs x = 2, y = -1 and y=x * Nth Term – e.g 5, 8, 11, 14 = 3n +2 Also if sequence is 5n + 1. The first term n=1 so 5x1+1=6 The second term n=2 so 5x2 +1 = 11 The third term n= 3 so 5x3 + 1 = 16 SHAPE, SPACE AND MEASURE * Angles – always give reasons clearly – remember isosceles triangles base angles equal Perimeter – around the outside Area – rectangle = base x height triangle = base x height divide by 2 Volume of a cube = base x height x length Names of 2D shapes and 3D shapes up to 10 sided Speed – Speed = Distance/Time Time/Distance Graphs – understand how these work Parallel Lines – lines equal distance apart – think train tracks Perpendicular Lines – meet at 90 degrees Symmetry – understand lines of symmetry (i.e. cut exactly in half) and rotational symmetry. (How many times it looks the same whilst rotated 360 degrees?) Tessellations – same shape over and over no gaps Bearings – remember to read where it is from. Bearings always measure from north, measure clockwise and give answers as 3 digits Little box into Big Box - practice How many tiles on a wall – practice * Drawing a triangle – use compass or protractor Construction/Loci – use a compass – single point is a circle/straight line is a line Elevations – remember elevations and plan (means birdseye view) Planes of symmetry – cut a 3D shape in half Transformations – learn the four plus associated information. Translation - vector (watch scale, 2 years ago the graph went in 2s) Enlargement - Scale Factor, Centre of Enlargement Metric Units – mm, cm, metres, km, litres, ml, grams, kg Imperial Units – inches, feet, yards, miles, gallons, pints, oz, pounds, stone Parts of a circle * Area and Circumference of a Circle * Pythagoras
