Do you know how to get to Sesame Street? This collection is designed to engage preschoolers in everyday learning by teaching core skills in Math, Literacy, STEM, and Social and Emotional Development. Here you'll find hundreds of videos, games, and printable materials to help you to excite even the youngest learners.

The earliest explorers did not have computers or satellites to help them know their exact location. The most accurate tool developed was the sextant to determine latitude and longitude. In this activity, the sextant is introduced and discussed with the class. Students will learn how a sextant can be a reliable tool that is still being used by today's navigators and how computers can help assure accuracy when measuring angles. Also, this activity will show how computers can be used to understand equations even when knowing how to do the math is unknown.

Students compare their own hand/foot span to Shaquille O'Neal's, then graph the data & construct a best-fit line. They can then use the information to investigate the proportionality of the human body.

Kids need multiple experiences to practice what they've learned. This lesson is one in a series about measuring and ordering objects.

In this Cyberchase video segment, the CyberSquad learns what happens to the area of a rectangle when the shape enclosed by the perimeter changes.

In this video from DragonflyTV, follow the investigation of Isaac and Anjali as they record, measure, and analyze data about how the Sun's position in the sky affects a solar-powered car's speed.

Student pairs design, build and test model vehicles capable of rolling down a ramp and then coasting freely as far as possible. The challenge is to make the vehicles entirely out of dry pasta using only adhesive (such as hot glue) to hold the components together. Creativity is encouraged and different types of pasta are provided to support different functions such as round pasta for wheels and sheet pasta for the chassis. Students become familiar with the concepts of gravitational potential energy, kinetic energy and rolling resistance. Teams follow the steps of the engineering design process as they design, test and redesign their small-sized vehicles, working within the project's material constraints. The winner of the competitive final event is the pasta car that travels the longest distance beyond the bottom of the ramp.

In this Cyberchase Media Gallery, explore key concepts about liquid volume, including standard units of liquid measure and how to convert between them. In the accompanying classroom activity, students create a complete conversion chart from the smallest measure (a fluid ounce) to our largest measure (a gallon). They use equations to prove that their conversions are accurate and learn to recognize mathematical relationships or patterns between the different measurements.

Students are introduced to the technology of flexible circuits, some applications and the photolithography fabrication process. They are challenged to determine if the fabrication process results in a change in the circuit dimensions since, as circuits get smaller and smaller (nano-circuits), this could become very problematic. The lesson prepares students to conduct the associated activity in which they perform statistical analysis (using Excel® and GeoGebra) to determine if the circuit dimension sizes before and after fabrication are in fact statistically different. A PowerPoint® presentation and post-quiz are provided. This lesson and its associated activity are suitable for use during the last six weeks of the AP Statistics course; see the topics and timing note for details.

Students learn that math is important in navigation and engineering. They learn about triangles and how they can help determine distances. Ancient land and sea navigators started with the most basic of navigation equations (speed x time = distance). Today, navigational satellites use equations that take into account the relative effects of space and time. However, even these high-tech wonders cannot be built without pure and simple math concepts — basic geometry and trigonometry — that have been used for thousands of years.

A 1st grade teacher uses a clip from Odd Squad to demonstrate measurement to her class. Students watch how Odd Squad agents use measurement to defeat the Hydroclops. They also model good mathematical practices such as being precise and persevering terms that are discussed and reinforced by the teacher. [5:09]

This lesson is great for young learners who like to collect things. It gives you ideas of ways to teach such concepts as classifying, sorting, arranging, multiplying, graphing, and measuring with collections of simple objects.

Students strengthen their communicate skills about measurements by learning the meaning of base units and derived units, including speed one of the most common derived units (distance/time). Working in groups, students measure the time for LEGO MINDSTORMS(TM) NXT robots to move a certain distance. The robots are started and stopped via touch sensors and programmed to display the distance traveled. Using their collected data, students complete a worksheet to calculate the robots' (mean/average) speeds at given motor powers.

Students learn about and use a right triangle to determine the width of a "pretend" river. Working in teams, they estimate of the width of the river, measure it and compare their results with classmates.

Sal discusses US customary units of volume or capacity such as teaspoon, fluid ounce, cup, pint, quart, and gallon. [7:21]

Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.

In this video from Cyberchase, Bianca is babysitting infant twins. As she tries to give each twin the same amount of liquid baby formula, she discovers that all the baby bottles are different shapes. Learn how she finds two that hold the same amount. In the accompanying classroom activity, students estimate which of four empty containers has the greatest capacity and then determine which one does by measuring actual volume.

In this lesson designed to enhance literacy skills, students examine how to use fractions to measure and help conserve freshwater resources.

Download these free worksheets to sharpen your skills in converting units. Sheets focus on converting between a wide variety of measurement units including mass, length, volume, temperature, time, and many more.

Can you throw a beanbag as far as the Olympic hammer or discus throwers? This activity introduces children to informal measures to compare distances, and is designed to be accessible to primary pupils at Key Stage 1.
