Several different processes of varying effectiveness can be used to purify air. 1  Thermodynamic sterilization (TSS) - This technology uses heat sterilization via a ceramic core with micro capillaries, which are heated to 200 Â°C (392 Â°F).
What is Common Core? The Common Core State Standards Initiative is a state-led effort that established a single set of educational standards for kindergarten through 12th grade in English language arts and mathematics.
The knowledge and skills students need to be prepared for mathematics in college, career, and life are woven throughout the mathematics standards. They do not include separate Anchor Standards like those used in the ELA/literacy standards. The Common Core concentrates on a clear set of math skills and concepts. Students will learn concepts in a more organized way both during the school year and across grades. The standards encourage students to solve real-world problems.
