Using supplemental and remedial worksheets:
There are many great websites online with math learning materials. This enables educators to teach more child-centered. Because of the availability of information, teachers and students can focus on individual strengths and weaknesses.
It is easy, for example, to print sets of different math worksheets and give these to individual students based on their abilities. The better students will receive more challenging and higher grade level materials and the weaker students will get remedial learning materials. Online worksheets can be used as supplemental and be done at school or at home
Students can benefit enormously from this and could even assess their own progress. Schools, teachers and parents need to embrace the new technologies and use these to improve the learning processes.
