Scholars determine distances on the coordinate plane to find areas. The instructional activity begins with a proof of the formula for the area of a parallelogram using the coordinate plane. Pupils use the coordinate plane to determine...

So what exactly is a random sample? The 15th part in a series of 25 introduces the class to the idea of selecting samples. The teacher leads a discussion about the idea of convenient samples and random samples. Pupils use a random...

Random sampling is as easy as choosing numbers. Teams use random numbers to create a sample of book lengths from a population of 150 books. The groups continue by developing a technique to create samples to compare from two populations...

Learners build confidence working with geometric tools and develop their construction techniques in the sixth lesson plan of the 29-part series. Given a geometric description, they use a compass, protractor, or ruler to create it....

Building on the previous activity in the 29-part series, the ninth activity asks individuals to construct a triangle given specific criteria. First, they are given three specific side lengths, followed by two sides and the included...

Using patty paper, classes determine that only one triangle is possible when given two specific angle measures and a side length. As the 10th instructional activity in the series of 29, young math scholars add these criteria to those...

Here is a wonderful lesson which has youngsters interview family and local elders about the seasonal history of their local area. They focus on climate change by asking questions about rainfall, temperature, the length of seasons, and...

Here's hoping that we can all fit into the pool. Given pictures and dimensions of a pool in tile lengths, scholars decide how many people can fit into the pool. This requires consideration of area, as well as the application of some...

The 2009 version of the first part of a national chemistry competition is posted for your use with olympiad hopefuls. Test takers deal with 60 multiple choice questions covering an entire year of chemistry curriculum. Use this to...

As to be expected from the American Chemical Society Olympiad Examinations Task Force, this 60-question test tops the charts in terms of excellence. It consists entirely of multiple choice questions designed to assess a year's worth of...

A n incredibly thorough worksheet on how to read and use a ruler awaits yours students. Students identify lines on the ruler and use the proper abbreviations for the lengths. Students answer ten questions about ruler usage.

Eighth graders conduct a "Length of Day Symposium." They complete a variety of activities and explorations regarding the earth's rotation, its revolution around the sun and the cyclic changes in climate and energy distribution on the...

Young mathematicians are shown a ruler, yardstick, tape measure and scale. They practice measuring length, width, height, and weight. They are then shown a thermometer, and discuss what a thermometer is used for. Everyone is shown how to...

Ten questions regarding volume of rectangular prisms are presented to your geometers, most of them requiring the multiplication of length, width, and height. The assignment is acutally an interactive resource in that learners answer...

Third graders find areas of rectangles by using square units, apply knowledge to real-life situations, and simplify method of counting square units by multiplying the length times the width.

Pupils calculate actual building measurements from a village map using concepts of ratios and scale in this ten instructional activity mini-unit. They practice measuring angles, multiplying decimals, estimating height and length, and...

After your math classes have been introduced to fractions (especially those with denominators of two, four, and eight), introduce them to fractions on a number line with this instructional activity. Using a meter length of tape, show...

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...

Fourth graders measure the change in the size of their shadow over time. They visit a fixed structure and record the date, the time, and the measurement of the length of their shadow. They do this over the course of the school year. They...

Eighth graders explain the relationship between the position of the sun, a city's latitude and shadow length. Ratio's, geometry, and algebra are used to determine the shadow lengths and building heights. A sun angle (altitude) charts to...

In this triangle worksheet, students explore the characteristics of triangles. They find the area of a pentagon, lengths of the sides of a triangle and the area of a quadrilateral. This two-page worksheet contains seven problems.

Weight, time, length, cost, and mass are all things we can measure. Learners are introduced to the concepts they'll need to know before embarking on any measurement adventure. They are introduced to each type of measurement and types of...

Identify the length, width, and height of prisms. Critical thinkers calculate the volume of prisms given small amounts of information. They derive the formula given the length, width and height.

Third graders use an online database to gather information about five dinosaurs that are of interest to them. Using a chart, they record their length, height and two interesting facts for each dinosaur. They draw a picture of the...
