Seymour A Cuisenaire Activity Page for grades 3-4. MIT Media Laboratory Manipulative materials such as Cuisenaire Rods and Pattern Blocks enable children to explore mathematical and scientific concepts such as number and shape through direct manipulation of physical objects. Alejandre A lesson plan with activities for investigating tessellations with pattern blocks, keyed to the NCTM Standards, and student tessellation samples. Reid's paper can be used both as a self-guided tour of teaching with algebra tiles, and as a set of activities for use with students.
Students then look for patterns and write the answer algebraically.
MN LEGO Logo projects are integrated into the science and computer curriculum of the Blake School. Tricks based on simple mathematics, but which to those who don't understand the mathematics may seem magical. Since these tricks are based on mathematics, they are relatively easy to do and are pretty close to foolproof. A discussion of evolution, inheritance, genes and mutation, the Prisoners' Dilemma, and how these and other biological themes relate to mathematics, with an applet that applies a genetic algorithm to solving the Toads and Frogs puzzle. The curriculum guide to elementary and secondary mathematics for the Canadian province of Saskatchewan.
