Type: Interactive/Game

Overview:

In this interactive activity, students will be led through steps to identify similar figures. There are teaching activities as well as practice activities available. A handout that describes strategies taught during the interactive is available to be printed. After utilizing this resource, the students can complete the short quiz to assess their understanding.

Content Standard(s):
Mathematics
MA2019 (2019)
Grade: 7
17. Solve problems involving scale drawings of geometric figures, including computation of actual lengths and areas from a scale drawing and reproduction of a scale drawing at a different scale.
Unpacked Content
Evidence Of Student Attainment:
Students:
  • Solve problems involving scale drawings.
  • Use a scale factor to reproduce a scale drawing at a different scale.
  • Determine the scale factor for a scale drawing.
Teacher Vocabulary:
  • Scale drawing
  • Reproduction
  • Scale factor
Knowledge:
Students know:
  • how to calculate actual measures such as area and perimeter from a scale drawing.
  • Scale factor impacts the length of line segments, but it does not change the angle measurements.
  • There is a proportional relationship between the corresponding sides of similar figures.
  • A proportion can be set up using the appropriate corresponding side lengths of two similar figures.
  • If a side length is unknown, a proportion can be solved to determine the measure of it.
Skills:
Students are able to:
  • find missing lengths on a scale drawing.
  • Use scale factors to compute actual lengths, perimeters, and areas in scale drawings.
  • Use a scale factor to reproduce a scale drawing at a different scale.
Understanding:
Students understand that:
  • scale factor can enlarge or reduce the size of a figure.
  • Scale drawings are proportional relationships.
  • Applying a scale factor less than one will shrink a figure.
  • Applying a scale factors greater than one will enlarge a figure.
Diverse Learning Needs:
Essential Skills:
Learning Objectives:
M.7.17.1: Define scale, scale drawings, length, area, and geometric figures.
M.7.17.2: Locate/use scale on a map.
M.7.17.3: Identify proportional relationships.
M.7.17.4: Recognize numeric patterns.
M.7.17.5: Recall how to solve proportions.

Prior Knowledge Skills:
  • Construct repeating and growing patterns with a variety of representations.
  • Continue an existing pattern.
  • Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations.
  • Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories.
  • Define unit rate, proportion, and rate.
  • Create a ratio or proportion from a given word problem.
