Module 7
Geometry and Measurement
Word Problems



Throughout this module, students will:
  • use all four operations to solve one and two-step word problems
  • make sense of problems and persevere in solving them
  • share strategies for problem solving and critique peer strategies
  • explore attributes of quadrilaterals and classify examples
  • use tangrams and tetrominoes to compose and decompose shapes
  • reason about relationships between shapes and attributes
  • tessellate to bridge geometry and perimeter
  • apply real world situations as they learn about perimeter as an attribute of plane figure
  • measure perimeter 
  • utilize line plots to draw conclusions about perimeter and area measurements
  • solve problems involving perimeter and area
Terminology Definition Illustration
Attribute any characteristic of a shape, including properties and other defining characteristics (e.g. straight sides, and non-defining characteristics (blue))
Diagonal a line that goes through vertices of a polygon that are not next to each other
Perimeter boundary or length of the boundary of a two-dimensional shape
Property description and/or characteristics of shapes (ie: having all sides equal in length)
Regular polygon polygon whose side lengths and interior angles are all equal
Tessellate to tile a plane without gaps or overlaps
Tetrominoes four squares arranged to form a shape so that every square shares at least one side with another square
