Students construct a bar graph with a given set of data. They calculate the ratio and percent of the data. Students discuss alternate ways of graphing the data as well as multiple strategies to approach the task.

Young scholars investigate ratio and proportion as they solve problems. In this algebra lesson, students calculate the percent increase on salaries and convert between decimals and percents to calculate. They rate job positions from...

Students relate data to coordinate graphs and plot points on this graph. They use minimum wage data to construct the graph. Students decide appropriate time intervals for the graphs. They share graphs with their classmates.

Students compare estimated lengths with actual lengths.

Pupils discuss the names of the people who work on various stuctures. They examine the many different roles people in construction can have. They match tools with the correct job and sing songs about workers.

Students differentiate between a relation and a function. In this algebra instructional activity, students identify a pair of coordinates as being a relation or a function. They analyze graphs for function as they solve word problems.

High schoolers investigate the Chernobyl nuclear disaster by mapping out the winds carrying radiation and viewing a short video about the aftermath and subsequent health problems. They then calculate the amount of radiation that people...

Students graph and solve equations and expressions. For this algebra lesson, students use simple factorization to simplify expressions. They review for an exam by doing basic algebra.

Students investigate octagons using words and shapes. In this geometry lesson, students discuss the shape of an octagon using physical and symbolic models. They make conjecture about the shape and relate it to the real world.
