About this worksheet
Each worksheet has 12 statements about a length, a weight, a temperature or an amount of liquid, to be judged reasonable or not.
This worksheet gives a measurement in a real situation and asks whether it is reasonable, covering length, weight and mass, temperature and liquid volume in both customary and metric units. Half the statements are true. The false ones are wrong in two different ways - some keep the number and move the unit, so a pencil becomes seven miles long, and others keep the unit and move the number, so a bathtub holds two gallons. The second kind cannot be answered by spotting an odd unit and needs a real sense of how big the quantity is. Sheets can be customized, turned into flash cards, or assigned for online learning.
