We iteratively designed and tested a set of activities and tools in which 10-14 year old students used the ToonTalk programming environment to construct models of sequences and series, and then shared their models and their observations about them utilising a web-based collaboration system. We report on the evolution of a design pattern (programming method) called “Streams” which enables students to engage in the process of summing and “hold the series in their hand”, and consequently make sophisticated arguments regarding the mathematical structures of the sequences without requiring the use of algebra. While the focus of this paper is mainly on the design of activities and its epistemological foundations, we include some illustrative examples of one group of students' work, which indicate the potential of the activities and tools for expressing and reflecting on deep mathematical ideas.Sat Jul 21 18:02:11 CEST 2007SudberyStandards at key stage 2, English, mathematics and science: a report for headteachers, class teachers and assessment coordinators on the 2001 National Curriculum assessments for 11-year-olds2002QCA assesment divisibility evaluation sequnces test sequncesCommunity for tag(s) sequnces
