What three-dimensional figure can be constructed using the three two-dimensional shapes below?
Students will create and use representations to organize, record, and communicate mathematical ideas. 3.R.1 Use verbal and written language, physical models, drawing charts, graphs, tables, symbols, and equations as representations 3.R.1a Have students use fraction strips to explore the concept of equivalent fractions. Have them create a list, writing the fractions in symbolic form. From the list, students can create a chart displaying the information. 3.R.2 Share mental images of mathematical ideas and understandings 3.R.2a Have the class envision adding 2 cookies to a plate that already contains 3 cookies. Ask them how many total cookies they picture on the plate. Then have them envision adding 3 cookies to a plate that already contains 2 cookies. Again, ask them how many cookies they picture on the plate. Explain the commutative property and discuss other situations using the commutative property. Have students state the definition of the commutative property. Apply this property to
