Advice to centres for preparation of candidates • Practise non-calculator skills regularly • Practise skills acquired in the earlier parts of the course regularly in order to improve retention e.g. DST calculations involving fractions of an hour mean from a frequency table express one quantity as a percentage of another simple interest for part of a year interpret statistics • Practise problem solving regularly
The Handouts • Candidate responses to a selection of 20 questions from Intermediate 1 Mathematics past papers. Responses chosen mainly to illustrate common errors made by candidates. • Marking Instructions for the 20 questions.
The 20 Questions • Q1-6 Non-calculator number skills • Q 7-9 Calculations involving time • Q10-20 various topics which candidates regularly find demanding
Q1-6 Number Skills • Add and subtract decimals • Equivalent fractions and decimals • Multiply & divide by multiples of 10, 100 & 1000 • Multiply simple 2-digit whole numbers • Multiply a mixed number by a whole number
Q7-9 Calculations involving time • Convert hours and minutes into decimal form in distance, speed and time questions • Convert seconds into minutes & seconds and minutes into hours & minutes • Know number of days & weeks in a year
Q10-20 Various topics which candidates regularly find demanding • Mean from a frequency table • Interpret median and range • Pie chart calculations • Interest (part year) • Straight line equations of the form x=a and y=b • Brackets and factors • Equations and inequalities • Express one quantity as a percentage of another • Area of composite shape involving a semi-circle
