Smile Metric Style
Students measure the length of student smiles and then record, order and graph their results.
Curated OER
The Golden Ratio
Seventh graders investigate a ratio found in nature and in numerous pieces of artwork throughout history. The lesson is cross-curricular and builds a sense of appreciation of design for students.
Curated OER
Smile Metric Style
Pupils take measurements using a metric ruler, find a sum of multiple metric measurements, and use a histogram to graph their results.
