Curriculum changes from MINZC to NZC Handout changes document Identify one major change from MINZC to NZC

Measurement Units and conversion Perimeter area and volume Circles Perimeter and area of rectangles Volume and surface area of cuboids

Measurement Sort unit cards into appropriate categories

Measurement Converting units kg g mg 1000

Measurement Converting units km m cm mm

Measurement Circles Measure the circumference of the circle C Measure the diameter of the circle d Find C ÷ d

Measurement Cut your circle up into sectors along the lines. Arrange these pieces into an approximate parallelogram What is its approximate area?

Area of circle

Perimeter and Area of Rectangles Take 24 blocks and make a solid rectangle What is its area? What is its perimeter? Which rectangle has the largest perimeter? Which has the smallest?

Volume and Surface area Using 24 blocks again Make a cuboid, What is its volume What is its surface area? Which cuboid has the largest surface area Which has the smallest? How many cubes would you need to make a cube?

Geometry shapes symmetry transformations

Kite add 2 pairs equal sides Quadrilateral 4 sides add 1 pair parallel sides Trapezium add 1 pair parallel sides Parallelogram all 4 sides equal Rhombus Rectangle Square 4 sides equal all vertices right angles

True or false? All squares are rectangles All rectangles are squares A square is a rhombus Write your own

Describing shapes Choose a partner, take one of the cards Describe your picture to your partner using mathematical language, so that they can draw it When finished look at their drawing. Does it look like yours?

Reflective symmetry

Rotational symmetry

Make a design using shapes with reflective symmetryRotational symmetry

Transformations Reflection Rotation Translation Enlargement

Kowhaiwahi Make your kowhaiwhai using the koru Explain the transformations in it.
