4th Grade Questions for Math Lesson

Facilitator models how to convert a traditional math worksheet or list of problems into a math worksheet embedded with science content. Teachers then work on problems or worksheets distributed to each table.

Teaching math skills through problems based on science content makes lessons more relevant and more engaging.
Rewrite the math problems or worksheets to include the science content standards.

12 TN counties are in a climate study. Over a 10 year period 3/12 of the counties received no rain. During the same period 5/12 of the remaining counties received average rain. The remaining counties received no rain. What fraction of the counties are in a drought? Explain your answer.

The marine biologist discovered that in Habitat B of the Mississippi river, 5/8 of the endangered mussels were thriving, but in Habitat C of the river only 3/8 of the mussels were thriving.
