Learners construct their understanding of measurement and dimensions in this step-by-step approach that begins with an all group vocabulary introduction, consisting of measuring objects and dialoging using measurement vocabulary....

When is a foot not a foot? When you use the length of your own foot to measure distances, of course. To underscore the importance of standardized units of measurement, middle schoolers engage in a series of activities that ask them to...

Turn young mathematicians into landscape architects with this four-lesson series on area and perimeter. Beginning with a basic introduction to calculating perimeter and area using non-standard units of measurement, this...

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

How do you find the lengths of items that cannot be directly measured? The 13th installment in a series of 16 has pupils use the similarity content learned in an earlier resource to solve real-world problems. Class members determine...

It's a small (nanotechnology) world after all! The first segment of a six-part series gives an overview of nanotechnology, its principles and applications, and shares some of the engineering applications of nanotechnology. A...

Children gain first-hand experience with Native American agriculture while investigating the life cycle of plants with this engaging experiment. Focusing on what the natives called the Three Sisters - corn, beans, and squash - young...

Is it a right triangle or not? Introduce scholars to the converse of the Pythagorean Theorem with a lesson that also provides a proof by contradiction of the converse. Pupils use the converse to determine whether triangles with given...

Introduce your class to Mars with a resource that provides information about its size, location, length of day, length of year, number of moons, and average temperature. Also includes is information about the lans for past...

Embark on a year long investigation of the seasons with this 10-lesson earth science unit. After being introduced to different types of weather and the tools used to measure it, young scientists perform fun hands-on activities that...

There isn't a more popular geometry formula than the Pythagorean Theorem! Learners understand the special side relationships in a right triangle. They use the Pythagorean Theorem to find missing sides and to solve problems. They begin...

Handling and processing data is a big part of what real scientists do. Provide a way for your learners to explore graphs and data related to the animals that live on the African savannah. They begin their analysis by discussing what they...

Logical thinking is at the forefront of this jam-packed lesson, with young mathematicians not only investigating geometric concepts but also how they "know what they know". Through each activity and worksheet, learners wrestle with...

Congruent figures: two figures that want to be just like each other. Individuals learn to distinguish between figures that are congruent and those that are not. Measuring the lengths of line segments and angles helps in this endeavor.

Leave no student behind with this differentiated geometry unit on perimeter and area. Over the course of five lessons, young mathematicians explore these foundational concepts through a series of self-selected hands-on activities and...
