In grade 3, children learn some easy conversions between measurement units. For example, they convert a bigger unit into smaller units (2 ft into 24 inches or 4 cm into 40 mm). Depending on where you live and what standards you follow, students may also do this the other way around: write 36 inches as 3 ft or 300 cm as 3 m. At any rate, conversion problems in grade 3 should be relatively easy, because being able to change measuring units into others is based on the multiplication tables, which children are usually just learning in 3rd grade. Then again, the conversions are a great application of the multiplication tables, giving children a real-life context for the tables.
