While the newer method does require computer access for every child, most schools now have that capability. As children do more hands-on learning on computers and less in books, these programs are capable of reaching them on a level they can understand.
Children naturally love counting and doing puzzles, but for some reason, when you call it "math", all of the interest flies out the window! So how can you cater to this natural love of 'math' and keep it fun and interesting enough to keep children's interest?!
School administrators are responsible for choosing the type of curriculum taught to children. As long as they are learning, the curriculum is considered effective. Using computer games as a tool is one option available to today's schools.
There are both similarities and differences between the new computerized programs and the former method of writing in math workbooks, tearing out the pages and turning them in.
