Elapsed time is a skill developed by the single question that is the center of this activity. Fifth graders are asked to find out the time that is 2011 minutes after the beginning of 2011. This question addresses the standard that...

Young readers travel back to the time of the dinosaurs in this literature unit based on the story Dinosaurs Before Dark. Intended for use with upper-elementary special education students, this resource provides reading...

Students use literature (the story Rodeo Time) and appropriate manipulatives to learn and understand mathematics. In these creative thinking measurement lessons, students have a focal point on problem solving strategies while using...

A very simple example of a functional relationship between depth of water and time is shown here. In fact, it might be more useful to use a coastal tide book to better illustrate this real-world experience. Pupils are to count the number...

Your Algebra learners analyze and solve an exponential equation in this popular, real-life model of the cooling of a liquid.  

Here learners get to flex some serious algebraic muscles through an investigation of logistic growth. The properties of the constant terms in the logistic growth formula are unraveled in a short but content-dense...

Students can practice determining elapsed time when given a start time and an end time. They can switch between digital and analog clocks.

This project is an experiment in classical physics. You'll be following in Galileo's footsteps, and investigating Newton's laws of motion, but you'll be taking advantage of modern video recording technology to make your measurements. The...

Why is it important for good mathematicians to understand the concepts of date and time? Discover the reasons in this lesson that explores the real-world connections and includes two interactive games that help build time-telling skills.

Use this online stopwatch to learn about elapsed time. This timer can time three different events at once and has an alarm.

Take the math challenge. Can you figure out how long you have to wait in line to buy a ticket? An estimation and time measurement challenge from the NCTM Math Challenges for Families collection. Based on real-world themes and...

This is a general-use stopwatch that can serve any purpose, for any subject area. The stopwatch counts up and down, records times that events happen, and also includes a buzzer that will activate at any time the user chooses. Java is...

Build your measurement and time telling skills in this lesson where the hours are broken down into minutes. Lots of related vocabulary and common time referents presented. There are links available to interactive elapsed time and...

Since running a race car is VERY expensive, race engineers know a great deal about how speed, time and distance relate. In this activity, you will investigate the relationship between distance traveled, speed and elapsed time. You will...

At this one page website work on this challenge using your very best problem solving skills to find a reasonable answer. Actually, there are a number of solutions. When you find yours check the website to see the solutions already listed.

Students examine actual radioactive decay data collected in an honors chemistry class to find an equation which best fits the data and allows a person to predict the count after certain periods of time have elapsed. Students review all...

How about a math challenge for a sunny day at the beach? Apply your problem solving, number sense, and logical reasoning skills to find out how long it would take Helix to get sunburned using SPF 10 lotion. Discover why understanding...
