Mathematicians compare triangles at different scales. In this geometry lesson plan, high schoolers calculate the area and perimeter of triangles. They use the Ti to make observation of the change that takes place as the triangles are...

In this understanding percent learning exercise, students fill in the missing parts for examples of number of colored parts and total numbers and use them to complete charts and rewrite sentences using the exact amount of things and...

The introduction to the lesson mentions a sailor's limited capacity to store drinking water on his ship. Pupils then set up an overnight experiment to remove freshwater from salt water by distillation. There is a math and map activity to...

Students determine the validity of Charles' Law. In this Charles' Law lesson plan, students measure the volumes of a gas at two different temperatures. They determine the volume at a high temperature and predict using Charles' Law what...

High schoolers measure various dimensions of a male and a female dolls body and scale them proportionally to average human measurements. They calculate the appropriate scale factor (magnitude) to enlarge their doll and apply that scale...

Upper graders will solve equations using order of operations, and create equations that to play a fun math bowling game. They will bowl using dice to practice operations. Extensions are also included.

If members of your class wonder where they can use the math they learn in middle school, let them discover the answer. Learners apply geometry concepts of scale and measure to calculate the costs of framing a house addition.

Student identify the solution using geometric mean. In this geometry lesson, students create right triangles where the altitude of the triangle is the side containing the right angle. They modify shapes using Cabri software and observe...

Students demonstrate rates of decay of unstable nuclei can be measured. They understand ratios and multiplication of fractions. They simulate radioactive decay. They read about the accomplishments of scientists.

Pupils determine the theoretical probability of winning a game of marbles. Individuals compare the theoretical probability to experimental probability for the same game. They continue on to compare two different probability games.

Middle schoolers cut an index card to create three similar right triangles and explore the congruencies and proportions that exist. They investigate the properties of lines and concepts of congruency, similarity, tangency and symmetry of...

Aspiring astronomers solve problems involving mixed units of the same attribute, including time, money, length, and area. They convert large numbers into scientific notation, then compute and compare ratios to explain why drawing...

Sew up your unit on operations with decimals using this assessment task. Young mathematicians use given rules to determine the amount of fabric they need to sew a pair of pants. They must also fill in a partially complete bill for...

Fifth and sixth graders compare decimals to the place-value structure in the base-ten number system. They represent fractions as parts of unit wholes, as parts of a set, as locations on a number line, and as divisions of whole numbers....

Exponential growth is modeled by learners as they analyze and interpret the data presented in this real-life scenario centered on the destructive invasion of the Giant African Land Snail. Learners get a touch of history and practice...

Students measure, analyze, and compare the ancient Egyptian canon of proportions using a mummy, painted images, and photographs of people today.

Young scholars demonstrate and describe the effect of multiplying or dividing by a fraction less than or greater than one. They create and explain a variety of equivalent ratios that represent a given situation. Students draw a picture...

Young scholars use hypsometers to measure tall objects.

Students solve and verify the solution for unknown measures. In this geometry lesson plan, students identify the properties of circles. They use the arc, angle and segment relationship to find the missing measures.

In this earth and beyond worksheet, learners answer short answer questions about the atmosphere, the chemical compounds in Earth's atmosphere. Students visit different websites to conduct research of the discoveries of the scientist who...

Ninth graders find the height of every day objects using techniques learned through postulates that allow triangles in a problem to be similar. They calculate the length of a missing side and solve proportions.

High schoolers differentiate between similar and congruent triangles. In this geometry lesson, students identify the angles of triangles using the similarity theorem. They apply concepts of triangles to the real world.
