A Maths Dictionary for Kids is a wonderful site full of colorful and easily explained math definitions. For many of our trimester two standards (area and perimeter, radius and diameter, parallel/perpendicular/intersecting lines, etc.), these definitions are a great reference source. On several of the definition pages, there are also small interactive practices! It’s been listed on the Homework Help page for a while, but if you haven’t checked it out yet, head over there!

Today, while prepping for the new school year, I stumbled across MeeGenius. This is a new beta site that, in mere minutes, replicates the gift my mother gave us. Choose a free book from their list, add in your own names and a few choice details, and you’ve got a personalized book in seconds. I had to make one myself, just for fun! What a great way to engage your reluctant reader!

The World of Brian P. Cleary is the author’s quirky, kid-friendly website. There’s so much to see that it’s hard to direct you to any particular section of the site. You can test your knowledge on the parts of speech, write a “Crazy Cat Tale” (think Mad Libs), play the train game, read the words and poems of the week, review addition and subtraction, practice your measurements of length, and much more! Poke around for 30 seconds and you’ll find a place you like! Check it out!

In 2010, after revisiting the site, I see that FreeRice is an incredible place for students to practice facts for a wide range of subject areas while still earning rice to donate! Students can answer questions about art, chemistry, English grammar, geography, language learning, math, and of course…vocabulary! Students can also now click on a speaker next to a word to hear it read to them and can change the level of difficulty manually! Better than ever!
