Students explore the concept of right triangles. In this right triangle lesson, students construct a scale model of a tourist attraction similar to Fort Jefferson. Students research aerial photos of Fort Jefferson, then build their...

Sixth graders fill out worksheets to find the perimeter and area of rectangles. In this perimeter and area lesson plan, 6th graders color in the area and measure the perimeters.

Young scholars use standard rulers to measure the length of common classroom items - such as pencils, books, desk tops - in inches and centimeters, and measure weight in pounds. They also answer math questions, such as "How long is the...

Students explore vertical and horizontal measurement of large objects. In pairs, they measure the trunk, crown, and height of a tree, create a graph of their results, and compare their results with their classmates.

Young scholars measure their bodies. In this math lesson, students record their height and weight. Young scholars measure themselves in six months and observe any changes.

Students demonstrate measurement and estimation skills. In small groups, they are given a measurement, predict what object in the classroom is equal to that specific measurement, and record their data in a table that includes the...

In this measurement worksheet, students complete a graphic organizer, filling in items measure, tool used, unit of measurement and why it was chosen and why each measurement tool was chosen.

Just what does it take to show two rhombuses are similar? The assessment task asks pupils to develop an argument to show that given quadrilaterals are rhombuses. Class members also use their knowledge of similar triangles to show two...

Scientists use ice core samples to obtain temperatures of the earth from 400,000 years ago! The third of five lessons instructs pupils to interpret historical climate data to see changes over time. In part I, participants interpret...

Students investigate the importance of significant figures through measuring and estimating. In this estimation and significant figures lesson plan, students measure pieces of paper and round their figures to the nearest marking on the...

Second graders calculate mileage for a journey. In this place value and measurement lesson, 2nd graders read Johnny Appleseed, work in groups to locate his birthplace on a map, locate the other states he stopped in, and measure the...

In this customary units of length learning exercise, students draw five lines with different lengths, measure five lines to the nearest half inch and estimate the length of five widths.

In this lunar crater worksheet, learners use an image taken by the Lunar Orbiter spacecraft to find the scale of the image and determine the diameter of the lunar crater Tycho. They also find the size of the smallest and largest features...

Students determine which of the following parameters, slope, ice, temperature or basal condition affects the glacier speed the most. They create their own experiment to test what influences glacier speed and temperature of the ice.

Students find the areas of geometric shapes. In this geometry lesson students find and measure the sides, perimeters, and areas of quadrilaterals, triangles, and circles. Students relate the measures to the others by using formulas.

Students find the density of objects by finding their mass and their volume. In this density lesson plan, students determine the mass of objects, the find the volume by using formulas or by water displacement and they calculate the...

Students investigate density using film canisters filled with different density materials and larger objects of varying density. For this density lesson plan, students discuss the concept of density and rank film containers from dense to...

Students determine the relationship between bone length and height. In groups, they are told the race and gender of the individual and discuss how this affects height. They measure the lengths of the bones in metric measurements and...

Students explore the historical sequence of cultures throughout history. They demonstrate the ability to organize events in chronological order and demonstrate how time is measured and annotated.

Students construct and maintain a school garden. In this gardening lesson, students plan the construction of the garden by writing letters to local businesses asking for supplies and materials; students build the garden using their math...

In this Pan's highway activity, students read about the Cassini spacecraft that discovered how Pan clears out the ring debris in the outer A-ring system of Saturn. Students use an image taken by the satellite to find the scale of the...

Second graders participate in a review of how to use rulers and yard sticks while collecting measurement information. They measure assigned body parts and chart the data on collection sheets. They make a spreadsheet with the information...

First graders listen to a read aloud of Linda Williams, The Little Old Lady Who Was Not Afraid of Anything" before discussing Halloween. They measure pumpkins using chains of paper clips to find their length and width. Once they open the...

Pupils compare estimated lengths with actual lengths.
