Investigating area-folding-paper

  1. 1. Investigating Area by Folding Paper Day 1 5-MinutesFrom Mark Driscolls Fostering Geometric Thinking
  2. 2. Investigating Area• For each problem, start with a square sheet of paper and make folds in the sheet of paper to construct a new shape, then explain how you know the shape you constructed has the specified area.• Construct a square with exactly 1/4 the area of the original square. Explain how you know it has 1/4 the area.
  3. 3. Investigating Area by Folding Paper Day 2 5-MinutesFrom Mark Driscolls Fostering Geometric Thinking
  4. 4. Investigating Area• For each problem, start with a square sheet of paper and make folds in the sheet of paper to construct a new shape, then explain how you know the shape you constructed has the specified area.• Construct a triangle with exactly 1/4 the area of the original square. Explain how you know it has 1/4 the area.

  6. 6. Investigating Area• For each problem, start with a square sheet of paper and make folds in the sheet of paper to construct a new shape, then explain how you know the shape you constructed has the specified area.• Construct another triangle with exactly 1/4 the area of the original square that is not congruent to the previous triangle you constructed. Explain how you know it has 1/4 the area.

  8. 8. Investigating Area• For each problem, start with a square sheet of paper and make folds in the sheet of paper to construct a new shape, then explain how you know the shape you constructed has the specified area.• Construct a square with exactly 1/2 the area of the original square. Explain how you know it has 1/2 the area.

  10. 10. Investigating Area• For each problem, start with a square sheet of paper and make folds in the sheet of paper to construct a new shape, then explain how you know the shape you constructed has the specified area.• Construct another square with exactly 1/2 the area of the original square that is located in one of the four corners of the original square. Explain how you know it has 1/2 the area.
