Geometry & Measurement

## Featured Topic: Coordinate Geometry

Help students learn about coordinate geometry through various grid activities such as coordinate grid pictures and coordinate grid games such as Capture the Penguins pictured at right.   Younger students learn to graph in the space while older students learn to graph ordered pairs on the intersection of the two lines.

## Geometry

These activities support student development of spatial sense and foster familiarity with the mathematical vocabulary of geometry.

• Directions for making Symmetric Faces pictured at right.
• Symmetric Pumpkin Challenge requires students to complete the right side of a jack-o-lantern to create a symmetric figure.
• Snowflake Symmetry activity teaches students how to make a symmetric snowflake.   The snowflakes are mounted on construction paper and cut apart along a line of symmetry.   All snowflake halves are mixed in a pile and students must try to find the matching snowflakes.
• Jack-o-Lantern coordinate graphing activity
• Gingerbread House coordinate graphing activity
• Grab the Candy coordinate graphing game introduces students to the use of coordinate pairs to graph points.
• Gridlock, Jr. coordinate graphing game.

## Measurement

These activities help students make sense of measurement by measuring the world around them using appropriate units. The emphasis is on constructing meaning for the units as well as the instruments students use to measure length, capacity, etc.
