Your students can enjoy deciding which units should be used to measure different capacities with this fun campground-themed cut-and-paste activity. Descriptions of measurements are provided, and your students must decide whether they should be measured in millilitres or litres. All students will receive the same campground worksheet where they can paste their descriptions. There are then three differentiated versions of the descriptions. Two extra descriptions for each unit are added with every new version. Pages 2-3 include two sets of descriptions that can be cut in half along the black line to save paper. Page 4 has one set of descriptions. When you have decided which version to give to which students, you can print the number of copies that you need and start the activity. A handy answer sheet is provided with the resource.
