**Title:** Now You See Me...Now You Don't!

**Description:**
An animal’s physical characteristics, such as its body color, may give it a better chance of survival. For example, the body colors of many animals blend with their background.

**Title:** Understanding Distance, Speed, and Time Relationships

**Description:**
In this two-lesson unit, from Illuminations, students use a software simulation of two runners along a track. Students can control the speeds and starting points of the runners, watch the race and examine a graph of the time-versus-distance relationship. They examine graphs of related data and investigate scenarios involving constant rates of change.
**Standard(s): **

[MA2015] (5) 23: Use a pair of perpendicular number lines, called axes, to define a coordinate system with the intersection of the lines (the origin) arranged to coincide with the 0 on each line and a given point in the plane located by using an ordered pair of numbers, called its coordinates. Understand that the first number indicates how far to travel from the origin in the direction of one axis, and the second number indicates how far to travel in the direction of the second axis, with the convention that the names of the two axes and the coordinates correspond (e.g., *x*-axis and *x*-coordinate, *y*-axis and *y*-coordinate).

**Title:** Communicating about Mathematics Using Games: Playing Fraction Tracks

**Description:**
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 e-example from Illuminations contains an interactive version of a game that can be used in the grades 3-5 classroom to support students' learning about fractions. e-Math Investigations are selected e-examples from the electronic version of the Principles and Standards of School Mathematics (PSSM). The e-examples are part of the electronic version of the PSSM document. Given their interactive nature and focused discussion tied to the PSSM document, the e-examples are natural companions to the i-Math investigations.
