The Council for Economic Education has recently published their schedule of free professional development webinars that they are hosting in the first five months of 2019. The series begins next week on January 15th and runs weekly (mostly) through May 28th. All of the webinars are scheduled for 7pm Eastern Time. You can register for one webinar or all of the webinars.
There is a fairly wide range of topics scheduled for the professional development webinars offered by the CEE. Some of the topics that jumped out to me as I looked through the list include How to Make an Apple Pie and See the World: Economics and Geography, Daring to Dream: Using Picture Books to Teach Economics, and
Lawn Care for Fun and Profit.
On the topic of economics, last fall I updated my popular Life on Minimum Wage simulation game. You can view it here as a Google Doc.
