This resource from the National Library of Virtual Manipulatives shows students how to rename fractions to have a common denominator and then add them. It is appealing because it visually engages the students by showing them what happens to a unit (a rectangle is used here) as the denominator increases or decreases. As the denominator increases or decreases, the partitions are shown accordingly, and the effect on the numerator is shown as well. This is a convenient, visual way to show students how to manipulate fractions for adding.

This article from the free online magazine Beyond Weather and the Water Cycle provides appropriate science lessons for Grades K-5. The focus is on acquainting young learners with climate-change concepts that are not too complex for their grade level and will not frighten them. In each issue, the magazine develops articles around one of the seven essential principles of climate science. The author believes early lessons about water availability and extreme weather events will prepare students for complex climate concepts they will encounter in later grades.

The national shortage of highly qualified math and science teachers points to a need to focus more attention and resources on teacher preparation. However, physics faculty often have little time to spare for activities outside of traditional research and teaching. The National Science Foundation (NSF) has strongly supported teacher preparation efforts, primarily through the Directorate of Education and Human Resources. What may be lesser known is that the NSF "broader impacts" criterion opens the door for more conventional research proposals to include teacher preparation activities as well.

This article discusses an inquiry practice that encourages students to develop their mathematical thinking through discussion. The author describes examples of students taking ownership of their learning when they are encouraged to justify their positions through sound mathematical reasoning. This practice builds a foundation for formal proofs.

In this article master teacher Chris Opitz explains how he incorporates social and emotional learning into his daily math lessons.

The concepts that underlie the fourth essential principle of climate literacy ("Climate varies over space and time through both natural and man-made processes.") are too complex for students in early and upper-level elementary school, but the foundational knowledge can be taught within existing curriculums and standards. This foundational knowledge will lead to understanding in later years. The author shows the correlation to the national science education standards, identifies misconceptions among elementary school students, suggests formative assessment probes, and identifies lessons and activities to make curriculum connections. The free, online magazine Beyond Weather and the Water Cycle is based on the seven essential principles of the climate sciences.
