Visited the National Library of Virtual Manipulatives lately?
http://nlvm.usu.edu/en/nav/vlibrary.html is a great resource for all students-easy for students with limited mobility as well as students without mobility difficulties. Try the "complete the pattern" application (http://nlvm.usu.edu/en/nav/frames_asid_184_g_1_t_1.html)--it's fun! (My second favorite is the Sieve of Eratosthenes at http://nlvm.usu.edu/en/nav/frames_asid_158_g_1_t_1.html)
Clicking on the "Parent/Teacher" icon at the top of each page provides:
- Objectives
- Lesson Plan
- Extension
- Assessment
- Materials
- Cross References
Clicking on the "Standards" button takes you to the National Council of Teachers of Mathematics' Principles and Standards for School Mathematics page that correlates to the activity.
