Opinion: Improving new Math books

Many Math teachers from Teachers Training Colleges and other educational institutions from secondary level to tertiary level under the project Teaching Quality Improvement Project (TQI) have been trained from Canada.I have an opportunity to observe classes two of them. They have some wonderful ideas that can be introduced in our Math text books like Algebra Tiles; making algebra visual. There are many more interesting ideas can be included in the new math text books.
But none of them and some other expert people who have long experienced in this field were not involved in the text book writing.
Moreover, there is hardly find pictures in the one colour Math text books from VI-IX and if so the pictures so tiny to understand for the kids. To make understanding and attractive to students there is no alternative to make the text book four colours. Research shows that that kids learn better by visually or by doing.
There are a few misconceptions (the graph grade VII) mistakes and inconsistencies in the Math Text books. There are too many definitions ( in the grade VI, in ratio; simple ratio, mixed raito, … ). All Math books have been following toto in the previous Math books. But the teaching learning process and many more things have been changed a lot during the last 17 years (our previous Math books were written).
Please ask people through the internet and form a committee immediately with the experienced persons to have a wonderful math books for the kids from the next academic year.
Scripts on topics can also be asked through internet and award them those scripts will be selected for the NCTB text books and rest of the scripts can also uploaded in the websites for the kids and for the teachers as well.
