ITP thermometer ITP thermometer

View full screen in your browser.  This ITP displays a thermometer. The scale, range and the interval markers can be changed and a slider control can be dragged up and down the length of the thermometer to set the height of the column. A second marker indicates the last reading so that comparisons can be made. This marker can be fixed in position if required. The positive or absolute difference between two values can be displayed, and the change in the temperature as the marker is moved. The ITP can be used to develop children’s understanding of vertical scales and negative numbers in the context of temperature. The slider controls can be used to introduce and model strategies for addition and subtraction that involve positive and negative numbers. The language of number can be developed, giving meaning to calculations such as subtract negative 3 from negative 7.

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 - 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.
