K-2
This website offers practice in reading several different instruments: a thermometer, 2 kinds of scales, speedometer, a tachometer, graduated cylinder, and pressure meter. What's nice is that multiple problems can be generated either "on the line" of the scale, or randomly between the lines of the scale. A printable PDF with blank scales is also available.
 * Reading Scales**

This colorful, fun site features a balance scale (or teeter-totter) and several different animals that may be infinitely "cloned" ala SMART Notebook software. Students can compare the weight of individual animals, or try to balance the scale with the correct number of animals on each side. No unit of measurement is given, so students can discover how many "chickens" a dog weighs.
 * Balancing Animals**

3 pages of activities, many with worksheets, involving the conversion of mass units. Nice sound effects for feedback. The only thing that may be distracting is that each activity has a "watermark" that reads: "FOR EVALUATION ONLY"
 * Teaching Measures: Mass**

Students estimate how many smaller animals weigh the same as one larger animal, then test their estimates using a balance scale.
 * Estimating Animal Weight**

Too clever! Acting as a veterinarian, students weigh and measure the length and height of a variety of pets.
 * At the Vets**

3-5
This page uses the same animals as Balancing Animals (listed above), but allows you to weigh the animals in either grams or kilograms.
 * Balancing Animals With Weights**

A FUN game involving weighing packages in kilograms and grams. It has different levels of difficulty and is great for reading scales. Convert Kg to G. The scale is difficult to read from far away.
 * Mostly Postie**

This site provides four scales: up to 500g, 1kg, 5kg, and 6kg with decimal values. A reading is randomly generated, and students must type in their answer. The site will then check the student's answer and keep a running total of the number of correct answers.
 * Scales Reader**

A great website, but it requires typing or writing the answers in with the correct spelling of the units, not just the abbreviation. And British spellings are used! Therefore, this site will require more time and could be frustrating when using "litres" or "metres."
 * Understanding Measures**

There is a downloadable Excecutable file that must be installed on your computer to do this activity, or you may download the SWF file to use in SMART Notebook. Measuring scales allows one to add different masses of 1, 2, 5, 10, 50, 100 and 500 units to a scale pan. The scale intervals can be changed to challenge children to interpret different scales.
 * Measuring Scales**

This activity will demonstrate the "old fashioned" way of weighing several different objects in grams.
 * Balance Scales**

This activity is not as interactive as the balance scale activity, but it allows you to show an object's weight in both grams and kilograms, so it's good for practicing metric conversions.
 * Dial Scales**

3 pages of activities, many with worksheets, involving the conversion of mass units. Nice sound effects for feedback. The only thing that may be distracting is that each activity has a "watermark" that reads: "FOR EVALUATION ONLY"
 * Teaching Measures: Mass**

On this very attractive, colorful website from the BBC, students must measure the length of a package in cm, then weigh the package in grams or kilograms, and finally determine the correct postage stamp to put on the package from a table of sizes and weights. Some conversion of cm to m or g to kg is required at the more difficult levels.
 * Measures and Weights**

Students are presented with a balance scale and 2 different shapes. They must balance the scales knowing how much 1 shape weighs in terms of the other shape.
 * Weigh It Up**

Students add boxes of various weights in grams to a scale until they have 1 kilogram.
