Grade 8, March Unit  (@ 10 days)

Overview                                                                              
During the last two weeks of quarter 3, 8th graders will be able to find out how tall a building is by measuring shadows.  The steepness of a road will be analyzed to discover the slope of the road and how this relates to the percent grade.  The question “What makes a ski slope blue or black?” will be answered.   Pay close attention to the essential Questions. You may be asked to answer the questions at the end of this unit.  The next two weeks of March are set aside for CSAP testing.  Students will have an opportunity to show what they know on the Colorado State Assessment. 

Standards

Enduring Understandings

  • Numbers can be represented, ordered, and communicated in many different forms.

  • Solutions must be reasonable.

  • Algebra is a language.

  • Geometry is used to solve problems.

  • There are different ways of estimating.

Essential Questions

  • When and how should you use a number line to demonstrate the value of rational/irrational numbers?

  • When is the "correct" answer not the best solution?

  • How would you describe, analyze, and determine the rule of patterns from multiple representations?       

  • How do you solve problems involving the Pythagorean Theorem?

  • How do you decide and justify your problem solving technique?  

Standards Highest Frequency High Frequency Other Standards and E-Skills

Standard 1:   (Number Sense) Students develop number sense and use numbers and number relationships in problem solving situations and communicate the reasoning in solving these problems.
Apply proportional reasoning using similar triangles and scale factor

Standard 2:  (Algebra) Students use algebraic methods to explore, model and describe patterns and functions involving numbers, shapes, data, and graphs in problem-solving situations and communicate the reasoning used in solving these problems.
Describe algebraic and geometric patterns and make connections between tables, graphs, and rules

Standard 4: (Geometry) Students use geometric concepts, properties, and relationships in problem-solving situations and communicate the reasoning used in solving these problems.         
Use formulas and solve problems with area, perimeter, surface area, and volume of right prisms and cylinders
Apply ratios, proportions and similarity in problem solving situations

Standard 6:   (Computation) Students link concepts and procedures as they develop and use computational techniques, including estimation, mental arithmetic, paper-and-pencil, calculators, and computers, in problem-solving situations and communicate the reasoning involved in solving these problems. 
Use ratios, proportions, and percents to solve problems
