Reading Varying Scales
Estimate the number on a number line. Can be used to teach estimation and reading varying scales. Lots of choice of scale. Choose whole numbers, decimals or negative numbers, or create your own scale.
I ask children to write their estimates on mini-whiteboards, and then click on 'show divisions' and ask the children to re-assess their estimations.

KS2 Primary Framework:
Year 3:
Order whole numbers to at least 1000 and position them on a number line (Block A)
Read, to the nearest division and half-division, scales that are numbered or partially numbered (Block D)
Year 4:
Use positive and negative numbers in context and position them on a number line. Position one-place and two-place decimals on a number line (Block A and Block D)
Interpret intervals and divisions on partially numbered scales and record readings accurately, where appropriate to the nearest tenth of a unit (Block C)
Compare the impact of representations where scales have intervals of differing step size (Block C)
Interpret intervals and divisions on partially numbered scales and record readings accurately, where appropriate to the nearest tenth of a unit (Block D)
Year 5
Use knowledge of rounding, place value, number facts and inverse operations to estimate and check calculations (Block A and Block B)
Explain what each digit represents in whole numbers and decimals with up to two places, and partition, round and order these numbers (Block A)
Interpret a reading that lies between two unnumbered divisions on a scale (Block C and Block D)
Year 6:
Use decimal notation for tenths, hundredths and thousandths; partition, round and order decimals with up to three places, and position them on the number line (Block A)
