• 7th Grade Proportional and Non-Proportional

Relationships   Tables and graphs are representations we can use to determine proportionality.   The proportionality constant (k)/ unit rate is needed to show proportionality.  We finished the first segment of this unit with a Gallery Walk where students create posters, display them and review each other’s work as we worked through Lesson 6.  For  Lessons 7 - 10 we will be investigating the proportionality constant more closely.

7.RP.A.2b, 7RP.A.2c, 7RP.A.2d, and 7.EE.4b are the specific standards we will be using.  If you search these standards and Khan Academy you can find more information about those standards.

• 8th Grade: Writing and Solving Linear Equations

The property of equality means do the action on both sides of the equal sign and it will remain balanced.  Variables representing unknowns are being used as we solve for them.  Like terms, substitution, and simplify are vocabulary words that are being used more frequently. The distributive property is appearing often also.We have completed Lesson 4 Solving a Linear Equation and are moving to Lesson 5 Writing and Solving Linear Equations where problem solving is involved.

8.EE.C.7 is the focus standard. If you search this standard and Khan Academy you can find more information about the standard.
