This one isn't necessarily common core, but the math portions do support the common core. It also lends a little time to the often-overlooked subject of science! I just wanted to share my new book with you all.
This is a collection of 50 STEM (Science, Technology, Engineering, & Mathematics) science experiments for kids. Recommended for grades 3 and up. Each one has a snappy title, a brief description of the task required, the rules, and grading rubrics. These are very adjustable for your classroom, home, or homeschool needs.
They support learning in these technical fields in a fun, hands-on, and sometimes competitive way. Learn by doing, measuring, and designing, and then reflect upon it.
