Reflection
Eighth graders use a stencil to make a figure with which they discover the horizontal line of reflection, the vertical line of reflection, and the diagaonal line of reflection using coordinates.
Curated OER
Dimensional Space: Various Perspectives
Students use their understanding of 3D on 2D to make a representation of a 4D form on paper.
Curated OER
TOPSY TURVY MAPS
Eighth graders use the data analyzer and motion detector to collect data and measure distances. They create topographic maps drawn to scale of a given setup and relate the concepts to the creation of historical ocean maps.
