  • EXPLORE / TŪHURA

    EXPLORE / TŪHURA learning intentions:

    • We are EXPLORING.. appropriate scales, devices, and metric units for length, angle, and time.
    • We are EXPLORING.... side or edge lengths to find angles and lengths of similar triangles
    • We are EXPLORING... scales and ratio
    • We are EXPLORING ...simple linear proportions, including fractions and ratio
    • We are EXPLORING ...equivalent fractions
    • We are EXPLORING ... rules to describe linear relationships and quadratic functions
    • WE ARE EXPLORING.. the invariant properties of figures and objects under transformations ( enlargement).


    • Success Criteria: I can/have...

      • measure distance and angles using standard units of measurements
      • use angles and measurements to calculate the unknown side/ length
      • identify the hypotenuse, opposite side, adjacent side of a right angled triangle
      • identify a right angled isosceles triangles
      • understand equal lengths have equal opposite angles in a triangle
      • create a rule using right angled triangle for calculating unknown side - Pythagoras rule
      • create a proportional  rule for similar triangles using a right angled triangle to calculate the height of a wall
      • plot coordinates using 3 figure bearings and graph the coordinates
      • draw simple linear graphs
      • use linear graphs to understand linear equations
      • create linear equation rule of y = mx+c from any straight line graph
      • using y=mx +c predict the value of y when there is a change in x

      Activities:

      1. Using Spheros plan a route using 3 figure bearings on the playground.
      2.  Create 2 D shapes with spheros calculate angles, lengths, area, perimeter
      3. calculate speed using distance and time data
      4. plot a graph for speed using the rule y = mx +c
      5. use a A4 paper to create a clinometer,  ( right angled isosceles triangle)
      6. use properties of similar triangles to calculate height  (proportion)
      7. Test - review of past week's lessons. Self mark, buddy with higher level students to undo errors.
      8. Use gravity to calculate the height of the school building and confirm the height measurement by using the similar triangle method
