Two statements that can be found in almost any math curriculum are:
Students learn best if they are actively involved in their learning.
Students should be able to apply various strategies to solve problems.
This unit covering Solving a Simpler Problem is one of 9 units focusing on 8 strategies plus a series of Mixed Problems in which students decide on the most appropriate strategy to solve each problem.
The colorful graphics in each unit are specially designed to interest and motivate the students to try the problems.
Each unit comprises a Tutorial, a Worked Example and 6 colorful, motivational problems in which students are encouraged to apply the newly learned strategy.
All problems come with on screen hints and solutions.
