If you are ready to put together a grant proposal to obtain equipment
for your own classroom/dept./school, you might find some of these
links useful. There are many, many funding opportunities out there
that are the right size to cover your expenses.
A good place to start is the EducationWorld
website for grant-writing tips and links to other helpful sites,
including more tips and databases for grants available.
In general, most experts advise starting at the local level, such
as your building PTSA. If your price tag is higher than they can
fund, perhaps these local organizations would be willing to provide
matching funds taht you could leverage as you apply for other grants
to meet your needs. Also, think about what niche your school or
classroom might fill and target your efforts in those areas.
