Great progress is made in year 2 with measuring. Much of the work still concentrates on comparisons between different lengths, heights, weights and capacity but standard units of measurement (such as centimetres and metres) are also introduced.
Units of time are also introduced, including seconds, minutes, hours and days and the relationship between them. Reading clock faces to the quarter hour is another step forward.
I have a selection of resources on these topics, found in the Year 2 maths Worksheet category, under Measuring.
I would also especially recommend the material at urbrainy.com for these topics, as they have a great range of resources which can be viewed free of charge and up to ten sets of worksheets printed free.
