The Utah SEEd standards do not completely align with the NGSS standards so an additional Teachers Edition has been provided to all 4th and 5th grade teachers with the required curriculum. The student notebooks already have the additional resources included in them. For 4th grade, Standard 4.3.2 (Waves) is not covered in McGraw Hill perfectly. In the past, Earthquake movement (lesson 2) was used to model waves. If this works for you, please continue to use it.  If it doesn’t, a CSD-created Mini Unit has been created to replace this component from McGraw Hill.
