Students work on practical problems in which the complexity of computations extends to include addition and subtraction of three-digit numbers, multiplication by single digits, and division by a single-digit number using arrays.
Explore ways of representing decimals using mathematical notation and visual tools. Match a decimal fraction between 0 and 1 such as 0.7. Adjust units on a range of visual scales and other representations. Work with a random selection of two of these representations: common fraction, number line, counting frame, dial, array and pie chart. Match at least three decimals with each tool. This learning object is one in a series of nine objects.
