Study Jams, from Scholastic, are engaging activites for students to learn about math and science. That is, at least the free sample exercises available are — apparently you can pay to gain access to quite a few more.
They’re accessible to English Language Learners. The sample “Study Jams” are on fractions, math operations, the water cycle, and gas/liquids/solids.
I’m placing links to Study Jams both on my Math and Science pages.
