Ask them to do this to check the result of the outdoor investigation. Discuss the results and perhaps explore another example before returning to the classroom.Įxperience suggests that students involved physically in an investigation benefit further if they are asked to create a table top model to represent the outside activity. Tell the story of the snail and ask for guesses at the number of hours. The base line is numbered 0 and the other marks are numbered to 11.
Teams of students stand up along a base line and step out 11 normal steps chalking marks on the ground as they go. This investigation begins very well with physical involvement outside or in a multipurpose room. Tasks can also be modified to become whole class investigations which model how a mathematician works. Whole Class Investigation Tasks are an invitation for two students to work like a mathematician. Also read this story of how the staff prepare their students to produce this level of work. Read one such report from Connor Gibbins, Year 7, St. The task then becomes a major investigation with an assessment purpose, so ensure students are aware of your assessment rubric before they begin their project. Students can then set their own problem, explore it, find a number pattern and prepare a report (not necessarily written) to explain their investigation to someone else. the length of the time unit (eg: half hour units instead of one hour).A good iceberg question is to discuss what there is in the problem that could be changed, ie: identify the variables. The card indicates some of the depth of this task. There is always more to a task than is recorded on the card. Iceberg A task is the tip of a learning iceberg. algebraic representation, generalisation and manipulation.wooden block of equally spaced holes (the well) and a dowel plug (the snail).A classic problem with many directions to travel because of the what if questions that can be asked. There is a movement pattern implied already, which is made more visual by the materials, so there will be a matching number pattern and the possibility of a generalisation. How long will it take the snail to get out of the well. Years 2 - 10 SummaryĪ snail climbs up the wall of a well for given time but while resting slips back down a given amount.
