Scale Intervals Tool
Specify intervals to create your own ruler or weighing scales to measure weight, height and length.
An extremely useful tool for whole class teaching. Assess or extend your pupils' skills at reading values off scales: in the context of length/height or weight. The scale on the ruler (or weighing scales) can be modified to suit the ability of your class and your teaching requirements. Change the starting point, the major interval step and the number of major and minor intervals. These are displayed immediately on the scale, allowing you to tweak until you get an appropriate level of difficulty. All major scales are labelled, minor ones not. Use the arrows next to the parcel to increase or decrease its size, to give a variety of challenges to your pupils.
