Grade 4 GT Mathematics
Unit 6: Geometry (5.G)
During this unit,students rely on prior understanding of number lines as the foundation for using two perpendicular number lines to define a coordinate system. Students will focus on the naming convention that relates the coordinates in an ordered pair with their position on the xaxis and the yaxis, and will use this knowledge to plot points in the first quadrant and solve authentic problems. Students rely on prior understanding of polygons to understand that attributes of a category of twodimensional figures also belongs to all subcategories of that same category. Students use these attributes to classify twodimensional figures.

What will my child learn?
Students will:
Graph points on the coordinate plane to solve realworld and mathematical problems.
5.G.A.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., xaxis and xcoordinate, yaxis and ycoordinate).
Classify twodimensional figures into categories based on their properties.
5.G.B.3
Understand that attributes belonging to a category of twodimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.
5.G.B.4
Classify twodimensional figures in a hierarchy based on properties.
