CACTUS.
Peer reviewed Peer reviewed
Hyde, Hartley – Australian Mathematics Teacher, 1992
Utilizes LOGO to teach the concept of inequalities by programing the turtle to take random walks in the coordinate plane restricted to predetermined regions defined by inequalities. The students task is to discover the inequalities that define the illegal areas into which the turtle must not move. Provides examples and corresponding computer…

Towards Better Strategies for Thinking and Programming.
Peer reviewed Peer reviewed
Tuovinen, Juhani E.; Hill, Douglas M. – School Science and Mathematics, 1992
Offers LOGO as an environment that facilitates the development of cognitive strategies useful in problem solving. Presents LOGO activities requiring students to combine preprogramed procedures to produce worksheet patterns. Using this approach promotes using LOGO as a vehicle for problem solving and results in a more positive attitude toward LOGO.…
