Mathematical games can foster mathematical communication as students explain and justify their moves to one another. In addition, games can motivate students and engage them in thinking about and applying concepts and skills. This first part, Playing Fraction Track, contains an interactive version of a game (based on the work of Akers, Tierney, Evans, and Murray [1998]) that can be used in the grades 3–5 classroom to suport students' learning about fractions.  
By working on this activity, students have opportunities to think about how fractions are related to a unit whole, compare fractional parts of a whole, and find equivalent fractions, as discussed in the Number and Operations Standard. In the second part, The Role of the Teacher, two video clips illustrate communication about mathematics among a teacher and her students. The third part, Communication among Students, shows how activities like this allow students to use communication as a tool to deepen their understanding of mathematics, as described in the Communication Standard. In the fourth part, Reflecting on Practice, the teacher reflects on her own mathematical learning that occurs as a result of using activities like this game with her fifthgrade students.

Contains examples for grades: PreK2, 35, 68, and 912. The example shown here pertains to multiplying fractions and decimals. Learning about Multipliction Students can learn to visualize the effects of multiplying a fixed positive number by positive numbers greater than 1 and less than 1 with this tool. Using interactive figures, students can investigate how changing the height of a rectangle with a fixed width changes its area. 

As discussed in the Number Standard, understanding multiplication by fractions and decimals can be challenging for middlegrades students if experiences with multiplication by whole numbers have led them to believe that "multiplication makes bigger." In these dynamic figures, the rectangle represents the familiar area model of multiplication; changing the rectangle's height can help students see the effect of multiplying a fixed positive number by numbers greater than 1 and less than 1.
