Balancing scales - convert between g and kg Balancing scales - convert between g and kg

The scale is loaded with between 1 and 4 weights. The user then has to balance the scales, converting between g and kg in the process. There is a great deal of control over the level.

A great starter to explore addition, subtraction / difference and partitioning as well as the relationship between grams and kilograms. Levels include converting whole kg to g (and vice versa), converting fractions of kg (eg 1/4kg = 250g) and weights in kg to 1 and 2 decimal places.

ITP measuring cylinder ITP measuring cylinder

October 2012 - I have added a new game in which you read numbered and unnumbered scales on a range of different measuring equipment. Click here to play

View full screen in your browser.  This ITP allows you to control two taps that pour a liquid in and out of a measuring cylinder. You can set the scale on the cylinder to a maximum of 50, 100, 200, 500 or 1000 units and the scale interval to 1, 2, 5 or 10 units. You can simply turn the taps on and off and ask questions that involve prediction, addition and subtraction. Using the inlet and outlet controls to set the amount of liquid to pour in and out of the cylinder offers the opportunity for the introduction of multiplication (repeated addition) and division (repeated subtraction) too. A marker can be set to indicate an early quantity.

The ITP can be used to explore and consolidate the interpretation and reading of scales, mental calculation strategies and methods of recording. Using different scales can support children’s estimation skills and provides a context for problem solving involving capacity and volume.

Balancing Scales g and kg Balancing Scales g and kg

Add weights to either pan until they are balanced. Can be used to teach addition, subtraction, partitioning, and mass, as well as developing an understanding of the equals sign.


Choose from grams, whole kilograms or kilograms with either 1 or 2 decimal places.
