Reading Scales
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.

Balancing Animals
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.

Teaching Measures: Mass
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"

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

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

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

Mostly Postie
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.

Scales Reader
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.

Understanding Measures
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."

Measuring Scales
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.

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

Dial 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.

Teaching Measures: Mass
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"

Measures and Weights
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.

Weigh It Up
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.

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