### Conservation: The More Things Change The More They Stay the Same

This blog post describes a lesson with kindergarteners where they observe very short videos (linked from the posting) and discuss what they notice and wonder. These videos could be great for discussion for learners at many levels of math and language.

### Create a Graph

You and your students can use this online tool to create graphs.

### Desmos: Graphing

What if students could "play" with graphs and quickly see what changing a single component would do to a graph (such as changing the b in y =mx+b)? Desmos is user friendly and thoughtfully uses color and layout in ways that support students' understanding.

### Labor Mediator

"In this problem, student groups serve as mediators to settle a dispute between the owner and the union of a small manufacturing company. ... This is a really engaging problem that raises important questions about the way data, often perceived as being completely objective, can be biased and informed by perspective."

### Mean, Median, and Range: Open Middle

Students are asked to find a data set to satisfy certain criteria. There is a worksheet provided on the right-hand side of the website where students can record their attempts at answering this question and what they learned from each attempt.

### Representing Data with Grouped Frequency Graphs and Box Plots

"This lesson unit is intended to help you assess how well students are able to interpret frequency graphs that use grouped data and their associated box plots. In particular this unit aims to identify and help students who have difficulty interpreting information from frequency graphs and box plots; such as minimum and maximum values, medians and quartiles."

### Representing Variability with Mean, Median, Mode, and Range

This resource gives students practice with calculating the mean, median, mode, and range from a frequency chart. It also requires students to use a frequency chart to describe a possible data set, given information on the mean, median, mode, and range.
