Slackmath - QR Video Solutions to Math Problems

Slackmath is a neat use of QR codes developed by a Geoffrey Slack, a math teacher here in Maine. On Slackmath you will find dozens of PDFs of algebra problems (Geoffrey told me has plans for other subjects in the future). Each PDF contains QR codes next to the mathematics problems. After students complete the math problem they scan the QR code to check their answers and find a video explanation of how to solve the problem. Watch the explanatory video below to see this is in action.

Reading Bear Offers Fun Online Reading Lessons for Kids

Reading Bear is a free service that offers narrated lessons on recognizing and pronouncing letters and words. There are also some lessons on prefixes and suffixes. Students can control the pace of each lesson to match their needs.

After each lesson on Reading Bear students can take quizzes to test their skills. The quizzes present a picture and a set of words. Students have to match the correct word to the picture that they see. Through the narrator, students receive instant feedback on each question in the quiz.

Here is a five minute video overview of Reading Bear.

Applications for Education
Reading Bear could be a good independent activity or an activity that children work through with the assistance of a parent or tutor. Like most websites like it, Reading Bear isn't a replacement for in-person reading lessons, but it could be a great support and practice resource.

Celebrating Pi Day With Pies

I shared this last year, it's worth sharing again. 

Today is Pi Day! To celebrate Pi Day, Numberphile has released a fun video about calculating Pi with real pies. The three minute and fourteen second video explains Pi and how it can be calculated. An extended version of the video will be available tomorrow to those who subscribe to the Numberphile YouTube channel.

After showing the video above, you might want to follow up with this video, How Pi Was Nearly Changed to 3.2.
