Thank you so much (developers, teachers, film makers, and editors) for working so hard on this website. It has been an invaluable resource for me in many of my lessons. I usually work with high school age, so when I recently began teaching 3rd graders, this site was a life saver.

If any of you (teachers or parents) are looking for online math, reading/writing, vocab, science, and/or social studies exercises, read on. I use a website called Beestar for many of my students. It has free math exercises for grades 1-12 (and relatively inexpensive exercises for the other subjects). If you go to beestar.org (for 1-8) or hs.beestar.org (9-12) you can register and get 2 math exercises per week for an entire semester.

If you do register, please list my e-mail (love2teach101@gmail.com), as I am attempting to earn referral credit to donate to my students. Thanks!
