Young scholars practice measuring items with non standard units. In this units lesson plan, students measure shapes, lengths, and classroom objects.

Studets practice problem solving and comparison of quantities, ratios and prproportions. They develop a plan for determining the height of a flagpole complete with drawings and calculations. In addition, they complete a written...

Students explore the concept of equivalence as it relates to comparing concrete objects to determine greater or lesser attributes such as length and weight. In this pan balance-shapes lesson, students make estimations while verifying...

Children begin by making direct comparisons between objects and putting a number of objects into order according to length. They are also introduced to measuring with multi-link cubes which allows them to compare objects which cannot be...

In this trigonometry activity, learners find the lengths of triangles. They construct triangles and spirals. Students complete indirect measurement problems. They find the distance between objects and determine the volume of rectangular...

In this data analysis worksheet, learners solve and complete 4 different types of problems. First, they reduce the data provided to find the means, and graph the means in a line graph. Then, students graph the data from each mixture...

Students measure the perimeter and area of their polygons. In this geometry lesson plan, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side lengths of...

Ninth graders find the height of an object that would be difficult or impossible to measure directly. They construct and use a Clinometer to measure the angle of elevation (or depression). Students create a sketch of the measurement...

There's nothing quite like a glass of ice-cold, freshly squeezed lemonade. Lesson seven of this series explains how the water humans need to survive can come in many forms. Teach your class about how much water humans require every day...

Learners of all ages investigate area and perimeter through pentominoes. In this geometry lesson plan, students calculate the are and perimeter of different geometric shapes and describe the properties of similar and congruent shapes....

Students, in groups, measure a variety of physical components to several activities. They use both standard and non-standard forms of measurement and then develop conclusions about the use of units in measurement.

Students identify the length of an inch. For this measurement lesson, students read Inch by Inch and predict how many inches long various objects are. Students practice measuring the objects by using an inch ruler.

Students examine how to apply the principles of trigonometry in authentic measurement situations. They work in groups to determine the height of an object such as a flag pole by determine the angle from their position to the top.

Students discover and discuss relationships and functions between varying dependent variables and how they affect the period of the pendulum. They use graphing calculator to express the data collected in a graph, to analyze the graph,...

Students explore measurements by analyzing geometric shapes. In this surface area lesson, students identify the terms volume, weight, perimeter and area in order to find the requested measurements of specific polygons. Students utilize...

Second graders work with liters and milliliters for measurement.

Fourth graders build a balloon hovercraft, take direct measurements, answer critical questions, and make calculations using the data gathered in order to see the concept of acceleration as a change in velocity. They use a worksheet...

Fourth graders draw a rough floor plan of a house to scale without using a ruler to determine measurements. They see how architects use scale to draw blueprints, and solve math problems using scale.

Middle schoolers determine the level of accuracy needed for computations involving measurements and irrational numbers. They use the correct number of digits in computation to achieve an appropriate unit or level of accuracy when...
