7.10: Probability & Statistics: Tree Diagrams and the Counting Princ.

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.

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.

7.11: Probability and Statistics: Construct and Analyze Histograms

Describing Data Using Statistics Investigate the mean, median, mode, and range of a data set through its graph. Manipulate the data and watch how the mean, median, mode, and range change (or, in some cases, how they don't change).
  5 Minute Preview   Lesson Info
Histograms Change the values in a data set and examine how the dynamic histogram changes in response. Adjust the interval size of the histogram and see how the shape of the histogram is affected.

Reaction Time 2 (Graphs and Statistics) Test your reaction time by catching a falling ruler or clicking a target. Create a data set of experiment results, and calculate the range, mode, median, and mean of your data. Data can be displayed on a list, table, bar graph or dot plot. The Reaction Time 2 Student Exploration focuses on mean.

Graphing Skills Create a graph (bar graph, line graph, pie chart, or scatter plot) based on a given data set. Title the graph, label the axes, and choose a scale. Adjust the graph to fit the data, and then check your accuracy. The Gizmo can also be used to create a data table based on a given graph.

Trends in Scatter Plots Examine the scatter plot for a random data set with negative or positive correlation. Vary the correlation and explore how correlation is reflected in the scatter plot and the trend line.
  5 Minute Preview   Lesson Info
Populations and Samples Compare sample distributions drawn from population distributions. Predict characteristics of a population distribution based on a sample distribution and examine how well a small sample represents a given population.

7.4: Computation and Estimation: Solving problems using proportions

Beam to Moon (Ratios and Proportions) - Metric Apply ratios and proportions to find the weight of a person on the moon (or on another planet). Weigh an object on Earth and on the moon and weigh the person on Earth. Then set up and solve the proportion of the Earth weights to the moon weights.

Part-to-part and Part-to-whole Ratios Compare a ratio represented by an area with its percent, fraction, and decimal forms.
  5 Minute Preview   Lesson Info
Percents and Proportions Find a part from the percent and whole, a percent from the part and whole, or a whole from the part and percent using a graphic model.
  5 Minute Preview   Lesson Info
Proportions and Common Multipliers Complete a proportion using a graphical model. Use counters to fill cells in the numerators and denominators given. Use the visual pattern to determine how many counters to put in the missing numerator or denominator.

7.7: Geometry: Properties of Quadrilaterals

Classifying Quadrilaterals Apply constraints to a quadrilateral, and then reshape and resize it. Classify the figure by its constraints. Explore the differences between the different kinds of quadrilaterals.
  5 Minute Preview   Lesson Info
Special Parallelograms Apply constraints to a parallelogram and experiment with the resulting figure. What type of shape can you be sure that you have under each condition?

7.15: Patterns Funct. & Algebra: Inequalities for one step equations

Solving Linear Inequalities in One Variable Solve one-step inequalities in one variable. Graph the solution on a number line.
  5 Minute Preview   Lesson Info
Compound Inequalities Explore the graphs of two inequalities and find their union or intersection. Determine the relationship between the endpoints of the inequalities and the endpoints of the compound inequality.
  5 Minute Preview   Lesson Info
Fractions Greater than One (Fraction Tiles) Explore fractions greater than one with the Fractionator, a fraction-tile-making machine in the Gizmo. Create sums of fraction tiles on two number lines. Sums greater than one are shown as improper fractions on the top number line, and as mixed numbers on the bottom number line.
