math tasks

Grade 7
We have been using proportions, proportional graphs, proportional tables, and the resulting equations.  Today we worked Lesson 8 and compared wages of Amber and John expressed in different types of representations. We have practiced stating the characteristics of each and using those to analyze stories/context. Tomorrow we will continue these types of activities which review the concepts on the assessment we will be having Monday. Stories and their context bring meaning to the math patterns.

Grade 8
Linear equations writing and solving them are the focus.  Today we discussed Lesson 7 "Types of Solutions" and found there were three: one solution, no solution, and infinitely many solutions.  We will be looking at Lesson 8 Linear Equations in Disquise where we will use the cross-product for proportions and then solve the resulting equations.

math tasks

Grade 7
Recognizing proportional relationships are now being expressed in tables, graphs, and equations.  The context of the story allows us to recognize the independent variable, x, and dependent variable, y.
We are nearing the middle of the module and will be having an assessment next Monday.  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 and practice for these standards.

Grade 8
Practice with solving linear equations and recognizing the three types of solutions has been our focus. We will be continuing with this and including linear relationships written as proportions and solving those also.

math tasks

Grade 7
We have been working with proportional relationships and have established the characteristics in both tables and graphs.  Tables will be able to find a constant of proportionality, k, where x is multiplied by k to produce y.  The variables x and y are either given or developed through the context of a story. Graphs that are proportional create a straight line and pass through the origin, (0,0).  We are currently working on Lessons 8 & 9 developing the understanding of how to make these relationships into equations with x and y being preserved as variables and k becoming the constant of proportionality.

Grade 8
We have been writing and solving linear equations these are equations where the variables have exponents of 0 or 1 and they make straight lines that pass through the origin when graphed.  We are currently working on breaking word problems into pieces, converting them to symbolic notation, then solving them using the distributive property, combining of like terms, the property of equality (for all four basic operations) and other patterns.

Field Trip Reminder

Reminder that we have our field trip to Sterling Mountain tomorrow!  Please remember to bring comfortable shoes for our hike up the mountain.  We encourage students to bring a water bottle and some snacks.  Students may want to bring sunscreen-as we will be out in the open.  Also, students should dress in layers and may want to bring a light jacket/sweatshirt.  It may be cooler up closer to the summit.

math tasks

    • 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.
