Fri 28th Jun - Using a Compass accuratley mathematical constructions



LEARNING OBJECTVIE: To understand how to accurately construct a line bisector, an angle bisector ...without using a measuring device.

SUCCESS CRITERIA: You will be able to use a pencil, ruler and pair oc compasses to construct a variety of constructions

ENGAGEMENT ACTIVITY:


LESSON: Demonstrate how to set up and use a compass accurately and draw a circleflower pattern

Then show and practice the following constructions


  • Perpendicular bisector of a line segment
  • Bisecting an angle


  • Extension: Choose other constructions from this List

  • Copy a line segment
  • Perpendicular bisector of a line segment
  • Perpendicular from a line at a point
  • Perpendicular from a line through a point
  • Perpendicular from endpoint of a ray
  • Divide a segment into n equal parts
  • Parallel line through a point (angle copy method)
  • Parallel line through a point (rhombus method)

    Weds 26th June - Build Polyhedra, Learn Names of of Polyhedra we build and the re;lationship between Faces, Edges and vertices


    LEARNING OBJECTIVE: To discover the link between edges faces and sides, learn some names of Solid objects and build some more 3D objects
    SUCCESS CRITERIA: You will be able to name and spell correctly the names of 3D shapes, be able to describe the connection between edges, faces and sides and also be able to build a 3D shape from its net
    KEYWORDS: Cube, Tetrahedron, Octahedron, Dodecahedron, Icosahedron
    ENGAGEMENT ACTIVITY:Which Net? (Pages 2,4,6)
    The Platonic Solids

    LESSON: Look at shapes and then Copy and complete this table. This web site might be useful

    Help students find the relationship between faces edges and vertices.
    Get students to complete making their tetrahedrons from last week. When finished they can choose from Octahedron, Dodecahedron and icosahedrons to build
    PLENARY: Look at all shapes built

    Fri 14th - Using Rounding to find approximate solutions to calculations

    LEARNING OBJECTIVE: To develop Rounding and Estimating skills.
    SUCCESS CRITERIA: You will be able to use rounding to estimate the solution to problems 

    ENGAGEMENT ACTIVITY:

    Copy and complete the following table:
    To Nearest 10000 1000 100 10
    45,678 50,000 46,000 45,700 45680
    30,983 30,000 31,000 31,000 30,980
    980,981 980,000 981,000 981,000 980,990

    LESSON: Look at examples of rounding to estimate the answers to calculations:

    Use rounding to 1sf to find approximate answers to solutions
