Task 1

Fabric Designs

Student Task

Core Idea 4 Geometry and Measurement

Identify geometric shapes in fabric designs and complete six different symmetrical designs.

Use characteristics, properties, and relationships of twodimensional geometric shapes. Examine, compare, and analyze attributes of geometric figures.

? Classify two-dimensional shapes according to their properties

? Understand line symmetry and predict the results of sliding, flipping, or turning two-dimensional figures

? Investigate, describe, and reason about the results of combining and subdividing figures

Task 2

Squares and Circles

Student Task

Core Idea 3 Patterns, Functions, and Algebra

Use a pattern of squares and circles to extend the design and answer questions about the number of each in relationship to the other. Show understanding using words and/or numbers.

Understand patterns and use mathematical models to represent and to understand qualitative and quantitative relationships.

? Represent and analyze patterns and functions using words, tables, and graphs

? Find the results of a rule for a specific value ? Use inverse operations to solve multi-step problems ? Use pictorial and verbal representations to solve problems

involving unknowns ? Communicate mathematical thinking clearly and coherently
