Students then use words and symbols to record the comparison. The student uses place value to represent whole numbers and decimals. Clarifying Activity Students use base-ten blocks to model, record, read, and compare decimal numbers, with the 10 x 10 x 1 square flat representing one, the 10 x 1 x 1 rod representing one tenth, and the 1 x 1 x 1 small cube representing one hundredth. The student describes and compares fractional parts of whole objects or sets of objects. Clarifying Activity Students use pattern blocks to represent fractions.
Students record their observations in a table and look for patterns.
Clarifying Activity Students use Cuisenaire rods to build a wall in which one is represented by a train of rods. For example, an orange rod plus a red rod might represent one. Students then use the wall to identify equivalent fractions. The student describes and compares fractional parts of whole objects or sets of objects. Using their model, they build representations of mixed numbers.
