Dear parents,

The weekly homework is assigned at the end of every class period.   The students are clear about their homework assignments.  Almost all of the students in this class are entering their teenage years.  They are expected to be responsible for completion of their homework.  I will no longer send a separate email to parents regarding to the weekly homework assignments.

Please email me if you have any questions.

Homework: Make a CH4 tetrahedron model with paper and tape and bring it to next class

A regular tetrahedron is one in which all four faces are equilateral triangles.
