Students will collaboratively design and construct a cardboard boat using a variety of tools and methods which will float and hold 1 human in the school pool.

Measurement and common math are required to perform your job duties in nearly every aspect of conveyor manufacturing. I have compiled a list of skills relating to math and measurement that are essential for successful job performance. This include being able to:

Read a tape measure accurately
Add or subtract fractions
Convert fractions to decimal form
Use a decimal equivalent card or chart (drill gage)

Using the story "The Celebrated Jumping Frog of Calaveras County" by Mark Twain, learners simulate a jumping-frog contest and determine the distances "jumped." Learners record the distance of individual jumps in centimeters and determine the total distance jumped (the sum of the three separate jumps) and the official distance (the straight-line distance from the starting line to the end of the frog's third jump). Learners compare the range and median of the total distances with those of the official distances of the group.

This Java applet activity allows students to explore the various situations described in "The Chairs Around the Table" lesson (cataloged separately). The user can select Exploration mode, in which the number of chairs needed for a particular arrangement of tables is displayed; or Guess, in which the user is able to construct an arrangement and then predict the number of chairs. There are two types of tables to choose from and two different table arrangements. Instructions and exploration question are provide.

An applet for students to use in exploring the area and circumference of a circle in relation to its radius and diameter. When the radius is changed, the other measures automatically change and are shown on a board. Most importantly, the ratio between any pair of these measures can be shown.

Meet the Climate Trackers—a group of scientists who are using measurements to tell the story of climate change and inform the decisions that will shape our future. In the resources below, you’ll learn about these scientists and their lab, and discover why their research matters in real life. Grab your notebook to take notes as you explore!

Resources available for learning about this lab include:
• Interactive cards designed to introduce students to scientists in a more personal way
• A video with a personal story that explains why the lab's research matters in real life
• Questions to consider that will spark connection, reflection, and conversation
• An interactive video experience where you can ask questions of scientists in the lab and learn about their research
• An educator guide with information about standards alignment, curriculum connections, and tips for using the media resources

These resources are part of Meet the Lab, a collection of educational resources for middle school classrooms.

Accuracy of measurement in navigation depends very much on the situation. If a sailor's target is an island 200 km wide, sailing off center by 10 or 20 km is not a major problem. But, if the island were only 1 km wide, it would be missed if off just the smallest bit. Many of the measurements made while navigating involve angles, and a small error in the angle can translate to a much larger error in position when traveling long distances.

This lesson develops number skills, understanding of coin values, and the concept of equivalence. Students use coin blocks, concrete representations of the value of coins (pennies, nickels, dimes, and quarters), to compose and decompose values up to a dollar. The resource includes a 3-minute video for teachers on how to build the coin blocks prior to the lesson. An interactive game, Coin Box, provides additional practice for students and is cataloged separately.

In this Flash game, students may use a variety of activities to practice counting, collecting, exchanging, and making change for coins. Coin representations may show their amounts or not; coins may also be represented by coin tiles on a 10x10 grid, to help visualize their values. The five activities are: count, in which students determine the value of a given set of coins; collect, in which students choose coins to represent a given value; exchange, in which students use the smallest number of coins to represent a given value; change from coins, in which students are given a set of coins and asked how much change would be for a dollar (essentially counting up); and change from value, in which students are given a price owed (from a dollar) and asked to make change. There is a "bank" at the lower left side of the applet in which coins may be exchanged for other coins of the same value.

This lesson is to help students work in small groups or pairs to find items around the classroom to measure in non-standard and then standard units of measurement.  It helps focusing on the unit of measurement, organizing a ruler, and how to continue measuring in the case it is longer than a ruler.Materials:Attached Measuremnt SheetInchwormsPaperclipsInch RulersCentimeter Rulers Lesson:I begin by handing out the measurement actiivty sheet.  I get my students into small groups or parnters.  They then choose three items in the room they woudl like to measure.  You could brainstorm as a class a variety of items they could measure before hand to better control what the students are measuring.  I begin the first day having students write the item or drawing it.  They then begin to measure with paper clips and then do it again with inch worms.  We discuss what the answers are and if there are any outliers, why this may be.  If time allows, we then bring in our inch rulers.  The groups discuss how to measure if they run out of their ruler.  They then measure with inches and centimeter rulers, keeping track of the data.  We reconveine as a class to record and collect the data found; searching for any outliers again.  In the end, we review the importance of measurement, why using standard vs. non-standard units are beneficial and some basic "rules" to follow when measuring.

This unit contains two lessons which help students develop number sense through activities involving collection, representation, and analysis of data. Students also practice reading and writing large numbers and develop estimation skills. In Lesson 1, Every Breath You Take, students estimate the number of breaths taken during a specified time, experiment, and display real-life data. In Lesson 2, Making Your First Millions, students develop the concept of a million by working with smaller numerical units, such as blocks of 10 or 100, and then expanding the idea by multiplication or repeated addition. They analyze situations and identify patterns that will enable them to develop the concept of large numbers. Each lesson includes student activity sheets, an instructional plan, and extensions.

Students will measure water using grams, millileters and cubic centimeters to discover the density of water. Needed tools are balances, graduated cylinders, a cubic container for measuring cubic centimeters, rulers and water.

Student teams design and create LEGO® structures to house and protect temperature sensors. They leave their structures in undisturbed locations for a week, and regularly check and chart the temperatures. This activity engages students in the design and analysis aspects of engineering.

The CyberSquad tracks Digital position in time and then studies graphs to figure out what Hacker is scheming in this video from Cyberchase.

The purpose of this task is to illustrate through an absurd example the fact that in real life quantities are reported to a certain level of accuracy, and it does not make sense to treat them as having greater accuracy.

Students discover the mathematical constant phi, the golden ratio, through hands-on activities. They measure dimensions of "natural objects"—a star, a nautilus shell and human hand bones—and calculate ratios of the measured values, which are close to phi. Then students learn a basic definition of a mathematical sequence, specifically the Fibonacci sequence. By taking ratios of successive terms of the sequence, they find numbers close to phi. They solve a squares puzzle that creates an approximate Fibonacci spiral. Finally, the instructor demonstrates the rule of the Fibonacci sequence via a LEGO® MINDSTORMS® NXT robot equipped with a pen. The robot (already created as part of the companion activity, The Fibonacci Sequence & Robots) draws a Fibonacci spiral that is similar to the nautilus shape.

Students investigate the difference between qualitative and quantitative measurements and observations. By describing objects both qualitatively and quantitatively, they learn that both types of information are required for complete descriptions. Students discuss the characteristics of many objects, demonstrating how engineers use both qualitative and quantitative information in product design.

Unit Title: Dream Garden MeasurementsAuthor: Melissa WimmlerSchool: Discovery Charter School, Columbus School DistrictGrade Level: 2nd GradeContent Area(s): Math, Environmental ScienceContext: Our governance council is working on a school wide project to improve the lawn space in front of our school and create our dream garden. During this six-lesson unit the second-grade students estimated and accurately measured objects in the space and perimeter. The students calculated the area of the space and used square units to plan spaces and garden beds.

Students will construct a distance model of the solar system to scale, using colored beads as planets. The chart below shows the planets and asteroid belt in order, along with their distance from the sun in astronomical units
