Geometric Solids and Their Properties: In five interactive geometry investigations, students explore geometric solids and their properties. Within each lesson, students use visualization, spatial reasoning, and geometric modeling to solve problems.

#### Students Construction, Twists Ties, Construction Physics, Geometric Models, Geometry Investigations, Geometric Solid, Exploring Geometric, Coff Stirrers, Pipes Cleaners

#### Construct a Solid: For this lesson, students will need to work with a partner and construct one or more of the geometric solids out of coffee stirrers and twist ties, straws and pipe cleaners, toothpicks and gumdrops, or other available supplies. For example, a tetrahedron built out of straws is shown.

Making and Investigating Fraction Strips: Students make and use a set of fraction strips to represent the length model, discover fraction relationships, and work with equivalent fractions.

Petals Around the Rose: A puzzle involving five dice and a non-standard pattern is used to promote problem-solving skills.

#### Rose, Non Standards Patterns

Fun with Pattern Block Fractions: In this 5-lesson unit, students explore relationships among fractions through work with the region model. This early work with fraction relationships helps students make sense of basic fraction concepts and facilitates work with comparing and ordering fractions and working with equivalency.

#### Pattern Block

#### Pattern Block Fractions: This lesson builds on the previous two lessons by focusing on the identification of fractional parts of a region and by recording them in standard form. Students continue to develop communication skills by working together to express their understanding of fraction relationships and to record fractions in written form.

Multiply & Conquer: Students decompose 2-digit numbers, model area representations using the distributive property and partial product arrays, and align paper-and-pencil calculations with the arrays. The lessons provide conceptual understanding of what occurs in a 2-digit multiplication problem. Partial product models serve as transitions to understanding the standard multiplication algorithm.

Running Races: A number-line model is an effective tool for helping students to understand the process of multiplication and to learn multiplication facts. In this 5-lesson unit, students begin with a number-line model and extend it to investigate linear relationships with the Distance, Speed, and Time Simulation from NCTM's E-Examples. Students then progress to plotting points and graphing linear functions while continually learning and reinforcing basic multiplication facts.

#### Students Generation, Help Students

#### Number Line Journeys: In this lesson, students generate products using a number line model. Students are encouraged to predict the products and to answer puzzles involving multiplication.

Geometry in the World of Art: This 6-lesson unit connects geometry with art. Students explore geometric shapes and concepts using a virtual geoboard. Students use the Internet to research the Russian artist Wassily Kandinsky. They define geometric shapes and lines within his works and design their own piece of art using Kandinsky’s techniques and their knowledge of geometry.

Math Vocabulary Bingo: This lesson provides students an opportunity to assess their understanding of mathematical vocabulary as they relate to key concepts from the five content areas. Through the use of a familiar game format, Bingo, students will identify numbers 0‑75 that correspond to mathematical descriptions from math vocabulary clue cards.
