Bully, bullied, or bystander? Paul Langan's The Bully is the anchor text in a unit that examines bullying and violence. After a close reading of the text, readers imagine themselves as the characters and consider how they would react in...

Win the war of the worlds! Scholars solve a variety of problems related to an alien invasion. They determine where spaceships have landed on a coordinate map, devise a plan to avoid the aliens, observe the aliens, and break a code to...

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

Here's a fun collection of activities for helping youngsters develop body awareness, walking and running skills, spatial awareness, fine motor skills, and adaptive physical education skills such as following directions.

Statistics come front and center in this unit all about analyzing discrete data. Real-world situations yield data sets that the class then uses to tease out connections and conclusions. Beginning with the basic histogram and...

Young athletes put together the athletic skills they need to play different sports in the eighth week of this physical education unit. First they work on basic skills like running, jumping, kicking, throwing, and catching....

Is there a better way to display data to analyze it? Pupils represent data in a variety of ways using number lines, coordinate graphs, and tables. They determine that certain displays work with different types of data and use...

How many different ways can you model data? Scholars learn several in the final module in a series of nine. Learners model data with dot plots, box plots, histograms, and scatter plots. They also analyze the data based on the data...

This site provides great practice on the concept of estimating and rounding whole numbers. Students can first learn about the topic by watching a step by step instruction video that also points out areas of concern. Finally, students can...
