Jacqui Murray teaches at St. Mary’s, a school in southern California. Her sites are rather busy for my taste, but have lots of interesting links to content targeted to teachers and students.
She has a wordpress.com site titled Ask a Tech Teacher. Check the “Top Posts” (in left column) which include 32 Science Websites for Fifth Graders and 20 Great Research Websites for Kids.
She also has a wiki site for the school. Check the Favorite Links and Grade Level Standards (details how their school meets ISTE standards for 5th grade) pages.
She uses ProtoPage for grade-based home pages. It has lots of links, some interactive widgets, and more.
