Examples of designed software (Th!nklets)



The Thinklet
Algebra Expressions
has similar options, but works with with tree structures to overcome the limitations of the arrow chains.
Both th!nklets can be modelling tools in problem solving activities, but they can be used for investigating the structure of algebraic expressions as well. The th!nklets Algebra Arrows Problems 1 Algebra Arrows Problems 2 are designed for the this second application. Student have to find arrow chains for a given formula or to change one formula to another.
