I started off making a set of free task cards for upper elementary, but then I decided that the younger set should have some, too, so now there is something for almost everyone! Not only that, but both of these sets are also correlated with Common Core Standards.
Measurement Task Cards for Grades 2-3
To complete these cards, your students will be measuring things around your classroom. Before they measure, they must first make an estimate. Your students will not only enjoy measuring, but they will also seeing the difference between their estimates and the actual measurements.
Measurement for Grades 4-6
These cards feature math story problems involving length, volume, weight, and temperature. The cards are a kind of measurement grab-bag and will require basic operations, conversions, and logic to solve. A student answer sheet and an answer key are included so that students can check their work.
