Curated OER
Springy Legs
Fifth graders measure their body height and the height they can jump. They use these measurements in forms of ratios, fractions and decimals to describe their Springy Legs Factors (SLF). Students compare their SLFs to other people's...
Curated OER
Stem-and- Leaf Plots
Students are introduce to the notion of stem-and-leaf plots. They use stem-and-leaf plots to calculate the mean, median, and mode of a set of data. Students use computers to learn about stem-and-leaf plots.
Curated OER
Sampling Snoops
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.
Curated OER
Will There be Enough Water?
Students 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 compare and...
Curated OER
Water - Planning for the Future
Middle schoolers 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...
Curated OER
Balancing the Scales: Understanding Ratios
Students 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...
Curated OER
What's For Lunch? A Combination Sensation!
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.
Curated OER
What's the Chance?
Students 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.
Curated OER
Standard Deviation
Students find city temperatures and analyze their means to find the standard deviation. They calculate the standard deviation of monthly temperature means.
Curated OER
Hop To It!
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.
Curated OER
Estimation Investigation
Students view an interactive video to explore the concepts of estimation. They work cooperatively to measure, make comparisons, make predictions, and verify results.
Curated OER
Harry Potter Research Project
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.
Curated OER
Box Plots
Learners review the concept of median, explore how to calculate quartiles for any size data set and experience how to build a box plot.
Curated OER
Sets an the Venn Diagram
Young scholars explore the characteristics of sets and Venn Diagrams. Given data, students practice determining the placement of elements in a Venn Diagram. Young scholars discuss the correspondence between data sets and their...
Curated OER
Histograms and Bar Graphs
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...
