Tiling the Patio 4.NF.1 - Task 6 Domain Number & Operations- Fractions Cluster Extend understanding of fraction equivalence and ordering. Standard(s) 4.NF.1 Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions. Materials Paper, Pencil Task Covering the Patio Part 1: Cover the patio below with the same kind of tile.

Part 2: Now cover half of the patio. Complete the table below for how many tiles it would take to cover half of the tile.

Part 3: For one of the fractions above explain how multiplication can help you find equivalent fractions.

Tile error. B: 6, 3, 3/6. Tile C: 4, 2, 2/4. Tile D: 8, 4, 4/8.  Part 3: The student writes something about, “Multiplying both the numerator and the denominator by the same number will result in an equivalent fraction.”.
