Students develop a line graph based on distances that an RCX car drives in specified amounts of time. They then are given a specific amount of time for the car to drive and be asked to extrapolate the car's distance from the graph.

Learners read the novel Stone Fox by John Reynold Gardiner. Using Lego RCX units, students build and program sleds to re-enact the "home stretch" of the National Dog Sled Race.

Students work in groups that are engaged in different activities at different times. They watch the video "Madagascar" and collect data pertaining to the Fish Eagle's arm spam. They work together to perform mathematical computations...

Students use seconds, minutes, and hours. They then discuss the size of a thousand. After that they read time in digital or analogue form.

Students study rectangles. In this math lesson, students use numbers, measurements and geometry to draw rectangles of varying sizes.

Students recognize the correlation between the trash they dispose of around their school and the environmental hazards that face wildlife, specifically the Laysan albatross. They determine three ways that they can help the albatross chicks.

Young scholars use an Internet tool, The Take-Away Bar" to solve subtraction problems. They use mental strategies to subtract a two-digit number from a larger two-digit number. Students write and solve subtraction problems. They...

Students experiment with graphing. In this graphing introduction lesson, students complete four activities: 1) a bar graph based on class birthdays 2) an estimation graph of the raisins in raisin bread 3) another estimation example with...

This video illustrates a visual model for solving a word problem involving the division of fractions. The problem asks students to determine the width of a rectangular platypus burrow based on its length and area. In the accompanying...

In this exercise, students practice adding and subtracting fractions with unlike denominators word problems. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

The lesson explores how to round numbers. Explanations and examples are included in the tutorial.

Use Glencoe's randomly generated self-checking quiz to test your knowledge of estimating sums and differences. Each question has a "Hint" link to help. Choose the correct answer for each problem. At the bottom of the page click the...
