Understanding arrays is very similar to understanding the relationship between multiplication and area. Give your third graders an opportunity to practice identifying area models that relate repeated addition and multiplication. They...

Review the principles of scaling areas and draws a comparison to scaling volumes with a third dimensional measurement. The exercises continue with what happens to the volume if the dimensions are not multiplied by the same...

Second graders take a field trip to a nearby church or other historical building and examine it from a mathematical perspective. In groups, they calculate the seating capacity, describe the window patterns, differentiate types of...

First graders estimate length and height of items. They read the story of Jack and the Beanstalk and discuss estimation of size. Students predict the length and height of figures. They use lines and numbers on the centimeter rod and tape...

Playing with matches (unlit, of course) becomes an engaging learning experience in this fun instructional unit. Teach pupils how to apply properties of exponential functions to solve problems. They differentiate between quadratic and...

In this bar graphs and line graphs worksheet, students interpret bar graphs, line graphs, and box-and-whisker plots.  They find the measures of central tendency.  This three-page worksheet contains notes, vocabulary, and...

By splitting a rectangle into equal parts, scholars can see area as well as calculate it. First, they determine the area of a rectangle given its side lengths. Then, they use the space provided to segment it into four equal parts,...

Learners recognize that measuring tools can come in many different shapes and sizes. In this early childhood math lesson, students develop creative-thinking, math, and social skills as they use nontraditional measuring tools.

How fast is your class? Learners determine the amount of time it takes individuals to walk a given distance and calculate their speeds. Pupils solve distance, rate, and time problems using the formula and pay attention to the...

It's never too early to learn about grocery budgeting. Middle schoolers delve into the world of consumer math with a lesson that focuses on both healthy choices and real-world math applications. Groups work together to form a grocery...

Help young scientists connect with nature and learn about trees with a fun life science lesson. Heading out into the school yard, children choose a tree to adopt, taking measurements, writing descriptions, and drawing sketches of it in...

Break out the balances for this primary grade lesson on weight measurement. Using common elementary school manipulatives like unifix or snap cubes, young mathematicians determine the weight of four different classroom objects. A graphic...

Expand the the comparative language of young mathematicians with a hand-on weight measurement activity. Working independently or in pairs, children compare the weight of large wooden blocks to various other classroom objects, recording...

Serve up angle measurements on paper plates. Pupils use paper plates and paper-folding techniques to create a unit circle with conversions for special angles. Using their plates, learners explore the relationship between angle...

Exactly how small is a nanometer? Scholars investigate the scale of a nanometer by measuring classroom objects and converting these measurements to nanometers.

Young mathematicians collect data on the arm spans of classmates. Then they sort the data by measures of center, spread, and standard deviation. Finally, they compare groups, such as boys and girls, to interpret any differences. 

For many young children it seems obvious that longer objects are heavier than shorter objects. This assumption is put to the test as the class investigates the relationship between length and weight in a whole-group activity. Using a...

Does it ever seem like time is slipping through your fingers? Model the passing of time with an hourglass activity in which individuals determine whether hourglasses are the most efficient way to measure time.

Take young scholars on a trip through history with this unit on the mathematics and architecture of the Mayan civilization. Starting with a introduction to their base twenty number system and the symbols they used, this eight-lesson unit...

Curves ahead! Develop a numerical measurement of curvy-ness. The class is challenged to come up with a definition of curvy that can be applied to curves. The class members use their defined measurement to describe a curve.

How many cups does it take to reach the top? Learners attempt to answer this through a series of questions. They collect dimension information and apply it to creating a function. The lesson encourages various solution methods and...

Clarify the Common Core standards for your eighth grade mathematicians with this series of classroom displays. By rewriting each standard as an achievable "I can" statement, these posters give students clear goals to work toward...
