Students practice formulating a hypothesis and designing an experiment to test the hypothesis. They identify several sampling techniques they can use to test their hypotheses.

Middle schoolers investigate water usage, water available, and water demand historically in the local area. They use projections of water usage, availability and demand up to the year 2050. Students use graphs to relate as well as...

Students explore and examine the increases and/or decreases for water user groups: irrigation, municipal, manufacturing, steam electric power generation cooling, livestock, and mining. They utilize percentage changes during their...

Pupils conduct probability experiments with dice and coins. They watch a video for a variety of situations where calculating the probability is complicated by total number of possibilities. They solve problems presented in the video.

Learners are introduced to the concept of ratios. In groups, they convert sets of numbers into a ratio. After practicing, they use the ratios and proportions to solve story problems. They also calculate map distances and discover map...

Students combine different foods to make possible lunches and determine the specific combinations of lunches that can be made from a finite set of foods.

Second graders collect data by spinning two spinners and creating sums, organize the data, and make conclusions from the data. Each students makes a spinner. They spin and record the number of the section each time. Students work in...

Fifth graders collect and organize data from writing samples, use fractions and decimals to describe the experimental data, and use the experimental results to make predictions about the frequency of letter usage in the English language.

Students find city temperatures and analyze their means to find the standard deviation. They calculate the standard deviation of monthly temperature means.

Students explore the aspects of a frog's anatomy that allow it to be such a good jumper and jump and record the length of each jump to determine which style of jumping allows them to jump the farthest.

Pupils view an interactive video to explore the concepts of estimation. They work cooperatively to measure, make comparisons, make predictions, and verify results.

Students develop strategies to organize data while following teacher demonstration. They calculate the mean, median and mode of a data set while determining the relationships between the numbers. They analyze data from tables and double...

Students explore the dose response principle, an introduction to what the "natural log" (ln) is and how it behaves. They create and analyze a dose response graph.

Learners explore the characteristics of sets and Venn Diagrams. Given data, students practice determining the placement of elements in a Venn Diagram. Learners discuss the correspondence between data sets and their graphical...

Students work together to complete a research project on Harry Potter. They write a research question and develop a survey to give to their classmates. Using the results, they create a graph and draw conclusions about the data collected.

Students review the concept of median, explore how to calculate quartiles for any size data set and experience how to build a box plot.

Second graders ask questions and design an experiment to explore different spinners in "The Leap Frog" board game. They conduct their experiment, collect information and interpret the results using a graph.

Twelfth graders use the Internet to research information on NFL players and construct frequency distributions from the data. They calculate the mean, medium and analyze their data.

Students are introduced to histograms, bar graphs, and the concept of class interval. They use an activity and three discussions with supplemental exercises to help students explore how data can be graphically represented (and...

Pupils culminate a unit on measurement with a focus on area and perimeter. They design a floor plan of their dream room on graph paper showing the proper area and perimeter. They plan the budget for their room and make a 3-D scale model...

Fifth graders explore real-life situations of area and perimeter. They develop a list of real-life applications of area and perimeter, select a situation, and write a step-by-step procedure and diagram on graph paper for solving the...

Students collect, organize, and display data using a bar graph, line graph, pie graph, or picture graph. They write a summary describing the data represented and compare the graph to another graph in the class.

Fifth graders arrange the classroom using all the moveable objects and through the exploration of area and perimeter. They determine the area of the classroom, create and label model pieces of furniture using graph paper, and create a...

Students create a spreadsheet and graph using Open House attendance data.
