Traveling with Third

   Students will go beyond identifying two-dimensional shapes and their parts, such as edges and corners (vertices). Students will use their everyday experiences to help them envision three-dimensional shapes. We will use pattern blocks, geo-boards, and templates. We will also classify and name polygons (closed figures consisting of line segments connected endpoint to endpoint). 

   We will explore points, line segments, rays, and lines, and the relationships among them along with the geometric shapes that can be built from them. Students will construct angles, polygons, prisms, and pyramids. We will identify similarities and differences among 3-D shapes and regular polyhedrons. Please help your child find real-life examples of lines that are parallel (lines that never meet) such as railroad tracks. We will be using our “Math Vocabulary” to examine relationships among and classifications of geometric figures.

Vocabulary

Two-dimensional (2-D) shape, Three-dimensional (3-D) shape, base, cone, sphere, cylinder, parallel, face, polyhedron, prism, pyramid

 

 

Objectives

  • Identify, draw, and name line segments, lines, and rays.

  • Draw parallel and intersecting line segments, lines, and rays.

  • Draw angles as records of rotations

  • Know multiplication facts from the first set of Fact Triangles

  • Identify right angles

  • Identify and name 2-D and 3-D shapes

  • Identify symmetric figures and draw lines of symmetry

Games:

  • Angle Race: Players build angles with rubber bands and “race” to see who will be first to complete the last angle exactly on the 360 degree mark.

  • Baseball Multiplication: Players use multiplication facts to score runs. Team members take turns “pitching” by rolling two dice to get two factors. Then players on the “batting” team take turns multiplying the two factors and saying the product. 

  • Number top-It: As players pick each card, they must decide in which place-value box to place the card so that they end up with the largest number. 

  • Beat the Calculator: A “Calculator” (a player who uses a calculator to solve the problem) and a “Brain” (a player who solves the problem without a calculator) race to see who will be first to solve multiplication problems.

  • Touch-and-Match Quadrangles

 

Activities

  • Read together the book The Greedy Triangle by Marilyn Burns.

  • Read Lao Lao of Dragon Mountain, The Art of Shapes for Children and Adults, or Shapes, Shapes, Shapes.

  • Make a shape Museum at home. Label the shapes that you collect (i.e. cones, cylinders, spheres, etc.)

  • Ask your child to identify two- and three-dimensional shapes around the house.
