This lesson unit is intended to help teachers assess how well students: are able to use frequency graphs to identify a range of measures and make sense of this data in a real-world context; and understand that a large number of data points allow a frequency graph to be approximated by a continuous distribution.

This lesson unit is intended to help teachers assess how well students are able to interpret data using frequency graphs and box plots. In particular this unit aims to identify and help students who have difficulty figuring out the data points and spread of data from frequency graphs and box plots. It is advisable to use the lesson: Representing Data 1: Frequency Graphs, before this one.

This interactive activity adapted from the Wisconsin Online Resource Center challenges you to plan, measure, and calculate the correct amount of roofing material needed to reroof a house.

This course has been designed to help students focus learning on specific areas of improvement. Unlike a typical college course where you would complete lessons in chronological order, this course allows you to focus on specific skills. Modules include: Arithmetic Review, Percents, Geometric Figures, Measurement, and Statistics

Students solidify their understanding of the terms "circumference" and "rotation" through the use of LEGO MINDSTORMS(TM) NXT robotics components. They measure the circumference of robot wheels to determine how far the robot can travel during one rotation of an NXT motor. They sharpen their metric system measurement skills by precisely recording the length of a wheel's circumference in centimeters, as well as fractions of centimeters. Through this activity, students practice brainstorming ways to solve a problem when presented with a given scenario, improve their ability to measure and record lengths to different degrees of precision, and become familiar with common geometric terms (such as perimeter and rotation).

Add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. Relate the charges on ions to the number of ions in the formula of a salt. Calculate Ksp values.

This short video and interactive assessment activity is designed to teach third graders about selecting capacity by comparison.

This short video and interactive assessment activity is designed to teach fifth graders about converting capacities using illustrations (english units).

This short video and interactive assessment activity is designed to teach fourth graders about converting capacities using illustrations (english units).

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.

The purpose of this task is for students to select 2 numbers from a set that sum to 5 (or any other number).

This short video and interactive assessment activity is designed to teach fifth graders about single-unit, multi-step problems - word problems.

In this activity students become familiar with the words, Ňtaller/shorterÓ as they refer to height.

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

Students will measure the dimensions of containers in the garden to determine the volume of soil and work out computations based off the volume.

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.

In this activity students become familiar with the math vocabulary more/less/same and most/least as they count and compare small groups.

This activity builds on Sort and Count I. It also helps students become familiar with the math vocabulary more/less/same and most/least as they sort, count, and compare small groups of objects.

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.

Learn about the frequencies that combine to make the "sound fingerprints" of various instruments.
