7.9, 8.12: Probability

Spin the Big Wheel! (Probability) Step right up! Spin the big wheel! Each spin can result in no prize, a small prize, or a big prize. The wheel can be spun by 1, 10, or 100 players. Results are recorded on a frequency table or a circle graph. You can also design your own wheel and a sign that describes the probabilities for your wheel.

Independent and Dependent Events Compare the theoretical and experimental probabilities of drawing colored marbles from a bag. Record results of successive draws to find the experimental probability. Perform the drawings with replacement of the marbles to study independent events, or without replacement to explore dependent events.

Probability Simulations Experiment with spinners and compare the experimental probability of particular outcomes to the theoretical probability. Select the number of spinners, the number of sections on a spinner, and a favorable outcome of a spin. Then tally the number of favorable outcomes.

7.8, 8.6, 8.8: Angle Relationships & Transformations

Investigating Angle Theorems Explore the properties of complementary, supplementary, vertical, and adjacent angles using a dynamic figure.
  5 Minute Preview   Lesson Info
Dilations Dilate a figure and investigate its resized image. See how scaling a figure affects the coordinates of its vertices, both in (x, y) form and in matrix form.
  5 Minute Preview   Lesson Info
Reflections Reshape and resize a figure and examine how its reflection changes in response. Move the line of reflection and explore how the reflection is translated.
  5 Minute Preview   Lesson Info
Rotations, Reflections, and Translations Rotate, reflect, and translate a figure in the plane. Compare the translated figure to the original figure.
  5 Minute Preview   Lesson Info
Translations Translate a figure horizontally and vertically in the plane and examine the matrix representation of the translation.
  5 Minute Preview   Lesson Info
Rock Art (Transformations) Create your own rock art with ancient symbols. Each symbol can be translated, rotated, and reflected. After exploring each type of transformation, see if you can use them to match ancient rock paintings.

8.10, 8.11: 2-D Plan Figures

Pythagorean Theorem Explore the Pythagorean Theorem using a dynamic right triangle. Examine a visual, geometric application of the Pythagorean Theorem, using the areas of squares on the sides of the triangle.
  5 Minute Preview   Lesson Info
Pythagorean Theorem with a Geoboard Build right triangles in an interactive geoboard and build squares on the sides of the triangles to discover the Pythagorean Theorem.
  5 Minute Preview   Lesson Info
Distance Formula Explore the distance formula as an application of the Pythagorean theorem. Learn to see any two points as the endpoints of the hypotenuse of a right triangle. Drag those points and examine changes to the triangle and the distance calculation.

Area of Parallelograms Examine and manipulate a parallelogram and find its area. Explore the relationship between the area of a parallelogram and the area of a rectangle using an animation.
  5 Minute Preview   Lesson Info
Perimeter and Area of Rectangles Discover how to find the perimeter and area of a rectangle, and of a square (which is really just a special case of a rectangle).
  5 Minute Preview   Lesson Info
Area of Triangles Use a dynamic triangle to explore the area of a triangle. With the help of an animation, see that any triangle is always half of a parallelogram (with the same base and height). Likewise, a similar animation shows the connection between parallelograms and rectangles.

7.5, 8.7, 8.9: 3-D Figures

Prisms and Cylinders Vary the height and base-edge or radius length of a prism or cylinder and examine how its three-dimensional representation changes. Determine the area of the base and the volume of the solid. Compare the volume of an oblique prism or cylinder to the volume of a right prism or cylinder.
  5 Minute Preview   Lesson Info
Pyramids and Cones Vary the height and base-edge or radius length of a pyramid or cone and examine how its three-dimensional representation changes. Determine the area of the base and the volume of the solid. Compare the volume of a skew pyramid or cone to the volume of a right pyramid or cone.
