The Maine Mathematics and Science Alliance (MMSA) has a number of free resources focused on STEM education. If you are looking for curriculum, lesson plans, formative assessment, or information about the Next Generation Science Standards and Common Core State Standards you should take the time to visit mmsa.org. MMSA also has a listserv for math and science. If you decide to register, you can send and receive emails to and from a vast network of educators, and people involved in education related fields. The emails put out on the listserv are moderated to ensure all the opportunities are real and secure.
