Dotstorming is a tool that I have recommended for a few years for group brainstorming and informal assessment activities. It allows you to gather ideas from your students and then have students vote for the favorite idea added to a shared digital corkboard. Click here for my video overview of Dotstorming.

This morning an email went out to registered Dotstorming users to inform them of an upcoming change to the free plan. Starting on May 7th the free plan will be limited to one board per account. If you currently have more than that, those additional boards will be accessible for one more month. The paid plans on Dotstorming are rather reasonable at $5/month or $25 for six months of unlimited use. A school-wide plan for all teachers is also available.
