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.

Card Game - Matching Pairs Card Game - Matching Pairs

Match the pairs of cards with the same value. A great game to play as a mental starter. Over 50 levels to play including; addition, subtraction, multiplication, division, matching fractions and decimals and converting between measurements.

ITP Polygon ITP Polygon

View full screen in your browser.  This ITP displays regular polygons with 3 to 10 sides. A background grid can be revealed and hidden and the displayed polygon can be enlarged using the pointers on the polygon button. The polygon can be translated and rotated. A vertex on the polygon can be dragged to another position to change its shape and properties. Double clicking on a vertex allows you to add remove the vertex or to add an extra vertex at the mid point of an adjacent side. You can use the ruler or protractor to measure dragging it and using the circular button to rotate it to the required position.
The ITP can be used to explore the properties of regular and irregular polygons. Children’s understanding of the angular properties of polygons can be developed. Children’s hypotheses about properties of sides and internal and external angles can be verified by measurement. Using the grid, children can explore the areas of polygons; identify which polygon’s vertices fit onto the grid points and look at how they calculate the areas of rectilinear shapes.

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.
