So true!
We are getting back in the flow of learning as we move into the second semester! We will have winter ride on Tuesday. Be sure to do your homework and have it ready for class on Wednesday.

7th Grade Math – Mrs. VonFeldt & Mrs. Evans
This week, in 7th grade math, we will be applying the lessons that we learned with equations to writing and solving 2-step inequalities (Module 7). One of the most important differences between equations and inequalities is the number of possible solutions. The equations we have been solving have only one solution, while inequalities can have an infinite number of solutions. We can solve inequalities similarly to how we solved equations. We must isolate the variable by using the inverse operation, applying that operation to both sides of the inequality. We can add or subtract any positive or negative number to both sides of the inequality without invalidating its truth. We can also multiply or divide by any positive number without invalidating the truth of the inequality. However, if we multiply or divide by a NEGATIVE number, we must flip the sign of the inequality in order for it to remain true.
Here is an example of how to solve inequalities:

This week in 8th grade math we will be using a formula to find the volume of prisms and cylinders. Learning to use formulae effectively and well is a very important skill because we use formulas to do many things in life, such as changing between Celsius and Fahrenheit when measuring temperature. Here is a video to help students understand how to find the volume of prisms and cylinders.
Algebra – Mrs. VonFeldt
This week in Algebra we are continuing to solve systems of linear equations. So far, students can use three strategies: Graphing, Substitution, and Elimination to solve systems of two equations. This week we will learn that you can solve any system by multiplying to get equivalent equations before using one of the methods above. We will end the week looking at systems of inequalities and discuss how they are similar and different from systems of equalities.
