Topical practice with L1-L2 number and measure skills (plus a few at E3) and would make a good starter or homework activity. Most questions are based on recent data from the Big Freeze of January 2010. Topics include converting temperatures, converting between metric and Imperial units, proportion, negative nos. and percentrages.
The topical and problem solving nature also makes this very suitable for underpinning L1 and L2 Functional Maths.
