Fractions & Decimals TOPIC KNOWLEDGE/SKILLS RESOURCES NOTATION Use of brackets. Multiplying factor to be both +ve & -ve and combinations. e.g. 3(2x – 2) – 4(x – 3) [ Excluding the multiplication of two brackets.] Simplify e.g. y/3 x 9y/4 2/t x 5/4t2 Use of formulae. Negative Nos & Graphs NGM 2 ALGEBRA EQUATIONS & INEQUALITIES Setting up and solution of equations. Using brackets, to include e.g. 3(2x – 2) – 4(x – 3) = 12 x/2 + 3 = 5 x/2 + 3x/4 = 7 Similar simple inequations. Algebra GRAPHS Graphical work in all four quadrants. Plotting ANY form of the equation of a line. Regions (integral intercepts only) represented by simple linear inequalities. To include intersection of regions. Pupils should be able to “shade” or “leave unshaded”.

Calculate r given A or C. Calculate A from C. Calculate C from A. Work with sectors as fractions of circles. Arc length, area & perimeter. Use = 22/7, 3.14. Use calculator button. VOLUME Volume of prisms with rectangular or triangular x-section. (or combinations) Know the formulae V = r2h Calculate V, r, or h from knowledge of the others. COMPOUND MEASURES Work out e.g. average speed, density RESOURCES General Arith. Area & Vol. MMS Bk 4 Scissors Compasses. MMS Bk 5 Area & Vol. SPACE & SHAPE TOPIC KNOWLEDGE/SKILLS PYTHAGORAS Know the theorem and use it when ANY two sides are known. Integer and decimal solutions. Answers given to a sensible degree of accuracy !!! Familiarity with the 3,4,5 and 5,12,13 triangles. Use to calculate the distance between two points whose co-ords are given. TRANSFORM GEOMETRY Reflections – using mirror lines drawn in jotter. Mirror lines in co-ords x = ± a, y = ± b, y = x, x + y = 0 Rotations – drawings in jotter. Rotations in co-ords. Centre (0,0) and OTHERS. Angle ±90º, ±180º Enlargement – positive & negative integer factors. Centre inside or outside figure. Practical problems. Enlargement using co-ords. RESOURCES Matrices & Transforms GEOMAT (Use Worksheet) or DERIVE Tracing paper NGM 2 DATA HANDLING TOPIC DATA KNOWLEDGE/SKILLS RESOURCES Collection – use personal data about pupils Results of simple experiments e.g. coins Dice, spinners Interpretation – Mean roulette wheel. Median Mode Understand the need for different Stat measures & averages. diagrams from Above from raw data or frequency table. EXCEL spreadsheet Read calendars and timetables. Inclusive & exclusive dates. 24 hour clock. Easy scheduling. Ready reckoners – direct & inverse. Interpolation & extrapolation. Scatter graphs. Line of best fit by inspection. Flow diagrams PROBABILITY Elementary one-event from sample space. Compare experimental & theoretical Probability. Outcome of TWO events by listing or A table PROCESSES Pupils should be given the opportunity to persue simple Mathematical investigations, communicating what they have discovered in writing. Most of the investigations should arise naturally out of current work but there is also room for the interests and enthusiasms of the Teacher and/or pupils. Remember that Mathematical processes should be going on all the time ! Mathematics is about problem-solving. The most important “process” is the identification of the necessary technique(s) and/or equipment. MENTAL SKILLS should be exercised regularly – both the ability to retain and follow verbal instructions and to discuss Mathematics orally. CALCULATORS The calculator is to be regarded as a tool and not a prop. Where it can be used to extend or enhance the work this should be encouraged, but thorough understanding of processes should usually precede the use of a calculator in normal work. By the end of the year pupils should be fluent in the use of the calculator with negative numbers, the change of sign button, square and square root buttons, and begin to use the memory. The Summer written examination (80%) will consist of Question/Answer booklet. There will also be a non-calculator test of basic arithmetic ( 10% ) JUNE Extend simple sequences to give nth term e.g. 1, 4, 7, ………., 3n – 2 ½, ⅔, ¾, 4/5, ………, n/(n + 1)
