Volume-Surface Area Websites


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.

Reading Scales 2
More practice in reading various instruments: a weather station, in the lab, and in the workshop. Unlike the original Reading Scales activity, however, all of the readings are generated randomly, and they may or may not align with the scales markings.


Surface Area
This online activity includes a lesson, virtual manipulative, questions set, and real world applications. The real world applications are a nice way to connect the theory to real world problems involving surface area.
Measuring Cylinder
This activity must be downloaded and installed on your computer as a SWF file. It can be viewed in a browser window after downloading. Good practice for reading a graduated cylinder. Change the units and scale of the cylinder.

The capacity area of this website involves the use of a circular grid. Students will use addition and subtraction to solve simple equations using milliliters or decimal liters, and to convert milliliters to liters. Problems are generated randomly, and answers may be entered using an onscreen keyboard.

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

3D Boxes
Students are presented with random stacks of cubes and asked to determine how many cubes are in each stack. Using a pen to write on the screen, students can solve the problem mathematically, and using the numeric keypad they can enter their answers. No audio, and very little visual feedback, but good practice.

Cuboid Exploder
A 3 dimensional shape appears on the screen. This shape can be rotated and also "exploded" to show the individual cubes that make up the larger object. This is an excellent way to demonstrate how the formula for volume works.

How High?
Students are presented with two "tanks" of varying sizes and shapes. Based on the dimensions of both tanks, students must estimate the height of the liquid when it is poured into the second tank. By using the given dimensions, students can use the appropriate formula for calculating the volume and capacity of each tank.

Teaching Measures: Capacity
3 pages of activities, many with worksheets, involving the conversion of capacity and volume 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"

Filling With Litres
Presented with pictures of 8 different containers, students estimate the capacity, and then pour pitchers of water to determine how many litres each container holds.

Measuring Jugs
Given an assortment of pitchers with random volumes of liquid in ml, students pour the pitchers into a bottle until they have exactly 1 litre.
