This workshop session will consider the valuable mathematical concepts that children ages 9 – 11 encounter when creating patterns with TurtleStitch. TurtleStitch is a useful way of teaching mathematics in the classroom, or a means to highlight its application and improving school students fluency. Students are able to create any pattern they wish, provided they can work out how to describe i...
