| Important Notes | How to use this Scheme | Learning Styles | |
|
This is a real scheme of work, planned for a specific group of adult learners. It does not claim to be an 'ideal' example - merely a source of ideas and resources for other tutors. If you use any of the ideas in this scheme of work I would love to hear from you. THANKS! |
|
Learners completed learning
styles questionnaires during initial assessment. The scheme encompasses
a variety
of learning styles and teaching strategies but was planned for a
learning group where the predominant learning style was
visual. |

Notes on general lesson format After initial assessment every lesson includes time slots for individual work (see lesson plans and ILPs for details) generally working from the text book, worksheets or online tutorials. Lessons begin with a starter activity (normally mental maths) followed by group teaching and activities.
Lessons always finish with students filling in diary, adding notes to progress chart and discussing what they have done and what they will be doing next. |

Overhead Transparencies: This course uses a large number of OHTs from the CIMT Centre for Innovation in Mathematics Teaching (based at Plymouth University). This site is an excellent source of worksheets, OHTs, teaching ideas and interactive tutorials. The Year 7, 8 and 9 areas are particularly useful for this course. |

HD2/L1.1 show that some events are more likely to occur than others (a) understand that some events are impossible (b) that some events are certain to happen (b) know that some events are more likely to occur than others (c) understand the concept of possible outcomes, e.g. there are two possible outcomes for the gender of a baby (d) understand that some events can happen in more than one way, e.g. there are three possible ways of getting an odd number with the throw of a die (e) understand that probability is an expression of likelihood, and use terms such as a one in two chance HD2/L1.2 express the likelihood of an event using fractions, decimals and percentages with the probability scale of 0 to 1 (a) understand that the likelihood of an event is measured on a scale from 0 (impossible) to 1 (certain) (b) understand that likelihood (or probability) is expressed as the number of ways the event can happen divided by the total number of possible outcomes (c) understand that likelihood or probability can be written as a fraction, decimal or percentage, e.g. the likelihood that a coin will land heads-up is 50%, .5 or 1/2b – the expression there is a fifty-fifty chance is an expression of likelihood using percentages |
HD2/L2.1 identify the range of possible outcomes of combined events and record the information using diagrams or tables (a) understand that events are independent when the outcome of one does not influence the outcome of another, e.g. the gender of a baby does not influence the gender of a second one (b) understand that events are combined when the outcome depends on the separate outcome of each independent event, e.g. the likelihood that twins will both be girls (c) record the range of possible outcomes of combined events in tree diagrams or in tables
