Students estimate the height of trees on the school campus, and measure their circumferences. They develop a map of trees on the school site, conduct their measurements, and record the results on a data table.

Tie the unit together and see concepts click in your young mathematicians' minds. Scholars apply the properties of similar triangles to find heights of objects. They concentrate on the proportions built with known measures and solve to...

Determine the distance between two trees from afar. Pupils use an interactive resource to create two right triangles using trees and a plane. They determine the horizontal legs of each triangle to find the distance between the two trees.

Students work in pairs taking measurements of a tree. They measure the trunk, crown, and height using vertical and horizontal measurement. Then students create a bar graph using the information they gathered.

Fifth graders diagram and label the parts of a tree. For this lesson on how trees obtain food, 5th graders diagram and label the parts of a tree, and determine the diameter, height, and age of a tree.

In this similarity learning exercise, students use the characteristics of similar figures to determine the length of one side of a polygon, the height of a tree, or the shortest side of a triangle. They also identify similar figures. ...

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.

In this math word problems worksheet, students complete math word problems dealing with maple trees, syrup, and a sugar bush. Students complete 6 problems where they click on links and that contain growth rate, percentages, measurement,...

Students utilize triangulation techniques to determine altitudes of objects. An altitude locator is constructed and used to determine the height of a building or a tree. Tangent tables and formulas provide the ratio for the formula to...

In this geometry worksheet, students differentiate between direct and indirect measurements. They create a table with their findings. There are 9 questions.

Students pick a tree they see everyday. They measure the tree's circumference and estimate its height using similar triangles. Students are introduced to Computational Science. They use computers and calculators to compute values...

Students use formulas to design and create a table.  In this calculations lesson students create basal measuring tapes that will be used to measure woodlot stocking levels. 

In this geometry instructional activity, students examine the height of 4 trees. They tell which tree is the tallest, make comparisons in 2 questions. They look at a picture of a pen, and a blue strip which they compare to the given...

In this math worksheet, learners will work in small groups to measure the height of objects, such as trees, using their shadows. Students will be able to determine heights of objects that cannot be directly measured.

In this ordering by length worksheet, students with a partner study and analyze different ways to understand the concept of length better through comparing objects and pictures.

Middle schoolers arrange themselves into small groups. Each group chooses a distance to measure ( the distance between the slide and the swings, for instance). Person #1 walks the distance, counting the number of his or her steps. ...

Pairs of pupils get together in order to measure the heights and lengths of their shadows. They use these measurements in order to predict the height of other friends in class. A good activity to practice measuring things that cannot be...

Fourth graders, acting as foresters, determine timber volumes as sawtimber or pulpwood for marketing. They find the marketable value of a tree using its diameter and volume.

Students measure the height of items using an astrolabe.  In this latitude lesson students construct a sextant and determine height and latitude with it. 

Eighth graders use their knowledge of calculating the volume of cylinders to calculate the volume of trees. For this volume lesson plan, 8th graders identify why calculating the volume of cylinders would be valuable to a forester.

In this unit, 1st graders use measurement language and counting to compare objects in a variety of game situations. Students also practice the advanced concept of counting to advanced counting.

Third graders attempt to determine the height of a telephone pole or tree without climbing to the top.

Eighth graders measure height and shadow length of other students on a sunny day and develop a ratio. They apply the ratio to other students and objects using shadows to determine height.

In this activity, students will make a gauge to measure rainfall and see how much rain falls over several days.
