Students discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample is...

Third graders use estimation, fractions and decimals to determine the perimeter of objects in the classroom. They are given a worksheet with a list of the items on it. The worksheet has columns beside each of the items for estimation and...

Students study units of measure like cups, pints, quarts and gallons. They work in groups to create their own mixtures of trail mix using the measuring cups. Then they make a gorilla puzzle using a gallon bottle.

Students identify the parts of an engine using a graph. In this statistics lesson, students make a graph from their collected data. They calculate the volume of a cylinder using a line of regression and a scatter plot.

Students develop the concepts of flood stage, levees, floodplain, and the dynamics of river flooding. They construct river models and test various flow rates and volumes. This lesson has an excellent experiment for students to do.

Second graders accurately measure the distances they and their classmates jump. They determine the mean, median and mode of specific jumps. They are required to have two measurements for each classmate, one for standing long jump and one...

In this line and angles worksheet, students explore basic geometry vocabulary.  They classify polygons.  Students determine the area and perimeter of given shapes.  They examine the parts of a circle, find volume and...

Students complete computer activities about estimating if items are more or less than a given amount. In this estimation lesson plan, students also estimate measurements around the classroom.

In this care homework worksheet, students add, subtract, multiply and divide numbers with decimals.  They solve problems involving mixed numbers.  Students find the area and perimeter of triangles and rectangles.  This...

Students examine tessellations and their geometric properties. Students explore the concept of tessellations and lines, planes, angles, and polygons. Students experiment with the area and perimeter of polygons. Students analyze...

Enjoy a hands-on lesson that will certainly hold water with your classes. Young scientists design an experiment to determine the materials that absorb water the best. They test both man-made and nature-made materials and conduct...

Fifth graders use pattern blocks and triagular grid paper to reivew shape names, be introduced to the concept of a tiling of the plane, and determine which pattern blocks tile the plane. They are asked if they comprehend what a...

Pupils confirm the law of conservation of matter by weighing chewing gum before and after it is chewed.

Fifth graders estimate perimeter, area, and volume. They measure perimeter and area using nonstandard units of measurement. Students add and subtract non-standard units of measurement. They add mixed numbers and simplify the sum.

Third graders estimate the volume and mass of one marshmallow using appropriate standard units. They design and carry out an investigation to find the average of volume/mass of one marshmallow.

Middle schoolers estimate and accurately measure the size of angles communicate with the appropriate geometric terms and symbols to describe and name angles, lines, line segments, rays

Students explore the size of a kilometer and the time it takes to cover this distance. They develop a concept of a km. They measure a distance of 1 km and the time taken to cover it.

Fourth graders explore the different types of ways to measure the distance between Florida and Japan.

Fourth graders research a Florida fish to determine its length. They display this information on two index cards, which are cut to the shape of the head and the tail and attached to a string that they measure and cut to the correct...

Students discuss situations when it is useful to know exact weight of object as opposed to estimated weight, estimate weight of various items, weigh them on scale using ounces and pounds, and compare their weights on Guess Your Best...

Learners observe the process of transpiration in leaves. They measure how much water a leaf gives off in a 24-hour period, calculate the volume, and answer discussion questions.

Young scholars explore what happens to water as it goes from solid to liquid and back. In this state of matter lesson, students observe, measure, and describe water as it changes state.

Young scholars need to be able to calculate the volume and surface area of a cuboid as well as present a systematic list of results in order to justify the minimum case. The use of three factors of 100 is also important.

Students engage in a lesson that uses applied mathematics to find the solution to the design of a pool for a home. They design the pool based upon scale measurements that include perimeter and area of the pool area, water volume, and...
