5/23 Lesson 9.2.2 Pythagorean Theorem

1.  Warm-up:  Coach Nagler wants to build the frame for a giant wall to be used in next year's Tough Two.  The frame will be a triangle (see image below).  He has wooden boards of length 6, 8, and 13 feet.  Will he be able to build a triangle?  How do you know?

2.  Lesson 9.2.2 Pythagorean Theorem

• Pythagorean Theorem a la Shmoop.
• Pythagorean Theorem notes and vocab building:
• Hypotenuse
• Leg
• Problems 70 through 73 in teams

Homework:  Lesson 9.2.2 R/P #74-77

5/16 Lesson 6.2.5 Similar Shapes and Scale Factors

1.  Warm-up: Cryptogram

2.  Lesson 6.2.5 Similar Shapes and Scale Factors

• Complete Problems 86 through 91 in teams
• Check your answers to Problem 89 and 90 on the Red Light, Green Light board

No Homework tonight!  We will begin SBAC computer-adaptive test tomorrow

5/13 Lesson 6.2.4 Similar Figures and Transformations

1.  Warm-up: Cryptogram

2.  Lesson 6.2.4 Similar Figures and Transformations

So far in this chapter you have investigated transformations and similar figures.  Recall that reflections, rotations, and translations are all special cases of transformations that are called rigid transformations.  Today you will investigate how to use transformations to show that two figures are similar.

• Today's lesson requires that you use graph paper to record your translations.
• After completing a problem, a member from your team should check the Red Light, Green Light board for the correct answer.
• Complete Problems 76 through 79 in teams

No Homework this weekend!

5/11 SBAC Practice

Chapter 7/8 Make-up Test Thursday @ lunch

Log-on to a computer

1.  Review Ratio and Proportions challenge problems

• Is it proportional?
• y = k * x, where k is the constant of proportionality and x and y are two quantities related proportionally.
• The amount of apples (a) produced on a farm is proportional to the number of apple trees (t) planted on the farm.  This proportional relationship is given by the equation:   4a = 60t              If a farm plants 4 apple trees, how many apples should the farmers expect to produce?

2.  SBAC Practice: Number Sense

• No calculators.  Put a Post-It underneath the problems that are challenging

5/10 SBAC Practice

Log-in to a computer and take out your homework

1.  Review Donut Shop problem in teams

• Check and compare answers
• Review as whole-class

2.  Ratio and Proportions SBAC practice (Google Classroom)

• I had problems transferring the PowerPoint to Drive, so some questions don't show
• Also, there is at least 1 incorrect answer on the answer key.  Can you spot it?
