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...

Farming is full of mathematics, and it provides numerous real-world examples for young mathematicians to study. Here, we look at a cylinder-shaped storage silo that has one flat side. Given certain dimensions, students need to determine...

Address key vocabulary in the seventh grade Common Core Math Standards with this comprehensive list. A series of word cards is also provided that supports each term with images and examples, making this an excellent tool for teaching the...

"Fore!" All right, no one really yells this out in miniature golf, but this well-defined activity will have your charges using lots of numbers in their unique design of a miniature golf hole. Included in the activity criteria is the...

If you have ever injured your shoulder, you know it takes a while to improve your arm's range of motion. For this real-world example, young mathematicians gain insight into the world of physical therapy while they analyze a case study...

Pupils will analyze scales as related to models and real life in this geometry lesson. They work together to compare the dimensions on a model as compared to the real building.

Your class will use a TI calculator to drag vertices of rectangles and triangles to observe what happens to ratios of pairs of sides within each figure. They will apply the definition of similarity to identify similar shapes. The...

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...

Eighth graders understand that proportional enlargement of shapes doesn't change the angles of those shapes. In this similarity lesson, 8th graders complete exercises to create enlargements of shapes and understand similar shapes.

Young scholars use similar triangles and a sight tool to find the height and distance between large objects. In this similar triangles lesson plan, students use a constructed sight tool to measure the distance and height of an object...

Learners estimate the total number of species in Ecuador using the capture/recapture method. They collect data about each species and act as members of a science expedition to determine the total number of species by using mathematical...

Students gain appreciation for the drawings by Leonardo da Vinci. They show human emotion by drawing facial features in correct proportion - studying ratio of eye width to the rest of the facial features. They create values by varying...

Students use the terms: ratio, proportion, and measurement in their description of the life of a person one inch tall.

Designers measure their own rooms and produce a scale drawing. They use the Internet to visit sites to find the costs of purchasing new carpet, paint, or anything else they would like to add to their room. Using a $1500 budget, they will...

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....

In this similar triangles learning exercise, high schoolers solve 20 short answer problems. Students determine if two given triangles are similar.  High schoolers determine the type of similarity given two triangles. Students are...

Third graders practice measuring different objects. They discover the concepts of ratio and proportion and practice converting numbers into the correct unit. They read stories as well to help them with the concepts.

Students look at ratio, what it means for numbers or objects to be in a given ratio, and how ratios and fractions are related. They write and solve story problems which involve whole numbers, using addition, subtraction, multiplication,...

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...

Determine the right mix of cans of cat food. The resource consists of an assessment task to determine the cost to feed two cats for a specific number of days and requires scholars to interpret remainders within a context....

If a 150 lb. person can comfortably eat and digest a 1 lb. burger, then how large would the person be who can comfortably eat and digest a 350 lb. burger? For a burger that size, it would take either a large person or a class of really...

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.

Students explore and experiment with the concept do new kinds of insects appear after soil modification. They assess and review scientific methods of observation, predicting, variables, math skills, ratio, proportions, graphs and the art...
