## Integer Chess

**SKU:**

### Description

*Integer Chess*consists of five Power LearningTM games played on the coordinate plane. Players plot points and move along the lines as they try to arrange five pawns in a row. Implementing strategies challenges beginners and masters alike. Understanding of important algebraic concepts grows through play. The basic game and its variations--

*Capture, Refuge, Hide and Seek,*and

*Treasure Chest*

*--*provide intriguing settings for developing competence in graphing and making vector-like moves on the coordinate plane. For 2-4 players.

4794 Integer Chess

4.G.3 Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.

5.G.1 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).

5.G.2 Represent real world and mathematical problems by graphing points in the first quadrant of the coordinate plane, and interpret coordinate values of points in the context of the situation.

6.G.3 Draw polygons in the coordinate plane given coordinates for the vertices; use coordinates to find the length of a side joining points with the same first coordinate or the same second coordinate. Apply these techniques in the context of solving real-world and mathematical problems.

6.NS.5 Understand that positive and negative numbers are used together to describe quantities having opposite directions or values.

6.NS.6 Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane; recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes.
