### Shape sorter: modify tool

Examine examples of pairs of shapes. Use the Modify tool to rotate, enlarge, reduce and flip each shape in a pair, to work out its features. This learning object is one in a series of nine objects.

### Shape sorter: more shapes

Help sort single shapes, or pairs of shapes, in the shape factory. Examine examples of shapes that belong in the Yes set. Examine examples of shapes that do not belong in the set. Work out what features of the shapes are important and test your ideas by sorting some shapes. Then program the robot and see if it sorts the ...

### Toby jigsaw puzzle: assessment

Test your ability to complete a 2D jigsaw puzzle of twelve pieces. Look carefully at a photo of a puppy, then reassemble the picture by moving puzzle pieces and rotating them if necessary. Complete the puzzle in the fastest possible time, the least number of moves and without looking at the reference picture.

### Shape maker: simple shapes: assessment

Test your understanding of how the transformations of spinning and extruding can change some of the most basic 2D shapes (such as squares, triangles and circles) into various 3D shapes, such as cylinders, cones and different prisms. Visualise the effect of a particular transformation on a selected 2D shape. Predict whether ...

### Shape maker: complex shapes: assessment

Test your understanding of how the transformations of spinning and extruding can change some less basic 2D shapes (such as a pentagon, cross, crescent and trapezium) into specific atypical 3D shapes. Visualise the effect of a particular transformation on a selected 2D shape. Predict whether the result will match a given ...

### Flower symmetry - mathematics activities

The photograph shows the flowers of a five-petalled weed common in southern Australia, where it is called a soursob. The symmetry in this plant, and in many other naturally occurring examples, contributes to the human understanding of 'beauty'. The mathematical interest in the pentagon and its correlate, the pentagram, ...

### EagleCat: rotasym

Explore rotational symmetry. Observe how many times a shape will fit exactly into itself as it is rotated through 360° about its centre. Explore rotational symmetry in numbers, letters, regular polygons and other shapes. Relate the order of symmetry to the factors of 360°.
