Differentiated plans for Years 5 & 6 Fractions, decimals, percentages and ratios Ian Lowe, MAV Professional Officer, 2006 What do we have here? ilowe@mav.vic.edu.au Fractions and its associated ideas are difficult for children. But they are a major focus for VELS Standard 4 Years 5 and 6 for the average child. So extra effort is required to create a rich learning environment that can help children to understand and to achieve at their own level. This combined topic is given 4 to 5 weeks, depending on interruptions. This set of units one per semester for Years 5 & 6 could achieve this goal. It matches the specifications for VELS, but recognises that there will be a wide spread of achievement in each class. So children are differentiated into working groups by need, for some of the time only. There may be more than one group at any Standard, or some Standards may need to be combined. Plan a stimulating set of activities for homework review, such as spreadsheets. It also balances the toolbox requirements concepts and skills with the need to learn to apply those tools in problem solving situations. Hence there are whole class lessons (often from Maths300 or RIME) punctuating the toolbox development, at regular intervals. These are on the same topic, but do not attempt to mesh with the work done by each standard group. They ensure that Working Mathematically is always part of the learning process, integrated into each dimension. The mix of activities will provide a stimulating and rich learning environment, with students learning from and helping one another. Connections between topics will be made and reinforced, and the variety of learning styles will accommodate learners with different needs. How does it work? In Years 5 and 6 it is assumed that children will be working anywhere from Standard 2 to Standard 5. Probably most will be working on Standards 3 or 4. At regular intervals whole class lessons are taught to mixed ability groups. Around these are cycles of a fixed pattern of lessons. In Years 5 and 6, the cycle has three parts: teaching, worksheet or games, computer use. On any day all are taking place in the same classroom, so only a fraction of the resources are needed. But the cycle also works for the students: they follow the pattern teaching, worksheet, (problem solving) and computer. As a consequence, teaching is to a different group each day in a regular pattern. ing will be for a concentrated 20 minutes or so, and then the teacher will supervise the rest of the class. Instructions on the board will inform the other groups of what they are to do. Encourage students to help each other. What resources are needed? Access to 4 or 5 computers daily is expected. pods or laptop trolleys might be the best solution. Membership of Maths300 is a requirement; many schools have membership here is how to use it. The pages in the resources are listed for each day s lesson, but are summarised here. Sources are: MAV (Mathematical Association of Victoria), CC (Curriculum Corporation), LF (Learning Federation). ing: Guidelines in Number (MAV), Maths Continuum (DE&T), People count (MAV) Worksheets:, (MAV), No textbooks are listed, but use them as required if you wish. : (MAV), Learning Objects (LF) Problem solving: Problem Solving Task Centre (CC), RIME (MAV), Maths300 (CC), RIME 5&6 (MAV) How could it be adapted to different situations? There is no expectation that lessons are sequential. Blocks of time without follow up lead to memory loss. If your class does not have the range predicted, or you cannot manage three or four groups, you should adapt by ignoring columns. You may substitute other learning tasks at any time. If you run out of time, leave stuff out. In this rich environment you will be surprised how much is learned outside the planned activities. How do I assess the learning? Your observations, digital photographs and copies of children s work will be more useful than any external test. Above all, if children have not all learned the same things, they should not attempt the same test. 2
