In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again. Then they use a notebook (a few small squares of paper with 2 staples along one edge) and start folding the pages in half. Magnets and play dough are used to model the proton and electron cloud of an atom, and two play dough hydrogen atoms are "bonded" together to form a molecule. Intermolecular bonds between water molecules in different phases, physical changes, and chemical changes in the kitchen are also introduced. This activity was designed as a kit that could be checked out of the library, but the kit is not required. (less)

This 5-minute professional development video clip shows students engaged in the Common Core Practice Standard #6, as students explore fractions through fraction strips and a game. The learners attend to precision in terms of accurately adding fractions to one exact whole, communicating their ideas clearly, and recording results. Additional resources include a video transcript, teaching tips, and a link to a professional development reflection activity based upon the video. (less)

In this Science NetLinks lesson plan, students learn to see numerical relationships and how to solve complex problems by manipulating objects (beans) and solving equations. Working with a partner, students pack 8 bean bags (sandwich bags) by reading each rule and figuring out how many beans of each kind (red, lima and black) go in each bag; learners record answers in a table. For some bags there is only one possible solution, while for others there are several correct answers. Students can develop confidence in their answers even when they differ from those of their classmates. (less)

This activity helps learners learn about math through a real-world scenario. Three friends are baking cookies for their schooläóťs bake sale. Using real or pretend cookies and plates, learners figure out how many plates they need to fit a certain number of cookies. Then they calculate how many batches of cookies they need to make for the bake sale. This activity guide includes questions to ask, extensions, resources, standards, and blackline masters. (less)

Using batting averages, students will create ratios and convert them to rounded decimals (3 places). In addition, they will take decimals and determine several possible equivalent ratios. Then using the relationship that batting average = hits/at bats, the students can use proportions or equations to find either the number of hits or the number of at bats for a given situations.
