Learners step up to the plate as they first complete an assessment task using linear equations to determine the best company from which to buy baseball jerseys. They then evaluate provided sample responses identifying strengths and...

Learners explore the concept of slope.  For this Algebra I lesson, students investigate the definition of slope as rise over run or change in y compared to change in x.  The lesson includes a real-world problem in which the...

Fifth graders investigate data from maps to solve problems. For this data lesson, 5th graders study maps and collect data from each map. Students present their data in a variety of ways and calculate the mode, mean, median, and range.

Students use a shower curtain to represent a coordinate plane and then physically demonstrate their understanding or ordered pairs as they move from place to place.

Are we there yet?  Young trip planners learn about their state and plan a trip. They will select sites to see in three cities in their state, and record associated costs in a spreadsheet. While this was originally designed as a...

Here is a lesson containing a great activity based on coordinates, and the perimeters of shapes created using a given set of coordinates. After youngsters creat a shape on a grid based on some coordinate pairs, they must identify which...

Your class can become linear equations masters, as they calculate the rate of change of a function. They observe different types of coordinates as they relate to a graph, then use the Ti-navigator to move the line around and draw...

This is a great lesson from start to finish. With partners and on their own, learners write and solve linear equations and inequalities. They use manipulatives, group work, and an included worksheet to make magic with their problem...

Discuss with your oceanographers what forces cause nearshore upwelling and downwelling. Display a line of wind vectors alongside a graph of the temperatures so that they can discover whether or not they are related. Discussion questions...

As part of a unit devoted to the study of autobiographies, this one-day library session focuses on developing research skills. Class members locate and properly cite a sketch of a Creative Commons image, as well as record the call...

Eighth graders follow the teacher as they enter information into the graphing calculator. They investigate different graphs to explain the slope of a line, the y intercept, and parallel lines.

First graders are introduced to a coordinate graph. They are given a graph and follow directions to place stickers in the designated blocks. They write coordinate points to identify the placement of their stickers.

Eighth graders experiment with a bathroom scale, books and a plank to determine how weight readings change as distance is applied. They graph and interpret the results.

Fifth graders develop strategies for estimating ages, and illustrate results by graphing and interpreting scatter plots to compare x and y coordinates.

Third graders enter the results of their survey on a spreadsheet. They construct a bar graph showing the results.

Students discuss the natural and economic impact of forests and forestry. Using given statistics they construct different types of graphs in which they make observations and draw conclusions.
