Transformation Creations
Learners "transform" an image into something completely different using critical thinking skills and artistic abilities. They improve skills in using digital cameras and word processors.
Curated OER
Geoboard Squares
Students create squares of different sizes on a geoboard. They find and describe a pattern. Students use the pattern to determine the number of squares possible on a 10-by-10 geoboard. They create squares with a horizontal base (and...

Modern Mosaics (Grades 6-8)
Middle schoolers explore the elements of contrast, emphasis, pattern, and color schemes by identifying how the artist manipulated tesserae in the mosaic. They create original mosaics by manipulating torn paper to depict different...
Curated OER
Modeling Mania
Students describe techniques helpful in solving spatial problems which utilize the notion that a model is a simplified version of something complicated. They utilize methods such as sketching or drawing possible solutions to a problem.
