Mrs. Walls' Math Blog (Week of 5.6.19)

We will continue Chapter 11: Geometry and Fraction Concepts.  In this chapter, students will learn about three-dimensional and two-dimensional shapes.  They will also learn about equal parts of a whole.

Lessons this week include sorting two-dimensional shapes according to their attributes, and partitioning rectangles into equal-size squares and finding the total number of these squares.

Why teach this?
From buildings and bridges to bicycles and buttons, the objects around us are the result of people using geometry.  The attributes of different shapes that make up an object often have a specific purpose.  For example, the sides and the angles of objects are often a particular length for a reason.

Chapter 11 Vocabulary-
For each chapter, I will be providing a list of important vocabulary words related to our in class learning.  Developing student's math language is a great way to improve their problem solving skills (think of complex word problems!).
  • angle- a shape formed by two line segments that share the same endpoint
  • cone- a three-dimensional shape with a circular base and a point at the top
  • cube- a three-dimensional shape with six square faces
  • cylinder- a three-dimensional shape with two circular parallel bases and a curved surface
  • edge- where two faces of a three-dimensional shape meet
  • face- a polygon that is a flat surface of a three-dimensional shape
  • fourths- four equal parts
  • halves- two equal parts
  • hexagon- a polygon with six sides
  • pentagon- a polygon with five sides
  • quadrilateral- a polygon with four sides
  • rectangular prism- a three-dimensional shape with six faces that are rectangles
  • side- one of the line segments that forms a polygon
  • thirds- three equal parts
  • vertex- the point where 2 sides of a polygon meet or 3 or more edges of a three-dimensional shape meet
