3D Rocket Building

Students in 3M and 3-O again worked with virtual world technology during their maths session today. This time their challenge was to flip and rotate 3D objects to create a rocket ship. This was very difficult as they also had to learn how to ‘snap objects to the grid’ in order to align their objects with greater precision. I did not expect any students to complete this task as this was only the second or third time they had been exposed to this technology. Wow, was I proved wrong as a number of students did complete the task with amazing precision. Excellent work everyone 🙂

Stage 2 Three-Dimensional Space 1

Year 3 students, using virtual technology,  investigated, manipulated, transformed and even translated solid geometrical objects such as a cube, cylinder, pyramid, sphere, cone and triangular prism in their maths session today. Students used the  hollowed , cut paths, twisted, sheared tools whilst also learning to use the camera controls to help give them perspective when creating their objects  – the camera assisted with top view, side view and front view.

MA2-14MG makes, compares, sketches and names three-dimensional objects, including prisms, pyramids, cylinders, cones and spheres, and describes their features
Make models of three-dimensional objects and describe key features (ACMMG063)

  • identify and name three-dimensional objects as prisms (including cubes), pyramids, cylinders, cones and spheres
  • recognise and describe the use of three-dimensional objects in a variety of contexts, eg buildings, packaging (Communicating)
  • describe and compare curved surfaces and flat surfaces of cylinders, cones and spheres, and faces, edges and vertices of prisms (including cubes) and pyramids
  • describe similarities and differences between prisms (including cubes), pyramids, cylinders, cones and spheres (Communicating)

Students should be able to communicate using the following language: object, two-dimensional shape (2D shape), three-dimensional object (3D object), cone, cube, cylinder, prism, pyramid, sphere, surface, flat surface, curved surface, face, edge, vertex (vertices), net.

In geometry, the term ‘face’ refers to a flat surface with only straight edges, as in prisms and pyramids, eg a cube has six faces. Curved surfaces, such as those found in cylinders, cones and spheres, are not classified as ‘faces’. Similarly, flat surfaces with curved boundaries, such as the circular surfaces of cylinders and cones, are not ‘faces’.

The term ‘shape’ refers to a two-dimensional figure. The term ‘object’ refers to a three-dimensional figure.

Grade 3 Virtual Maths

The Framing Paper Consultation Report: Mathematics (ACARA, 2009, p. 9) states that “new and emerging technologies provide not just new tools for doing mathematics but also new possibilities for pedagogical approaches.”

Both 3M and 3-O are using our virtual world technology Sim-on-a-Stick to complete mathematical tasks based on the NSW maths syllabus substrands of Data, Measurement, Space and Geometry. Each week student groups complete tasks relating to these outcomes using a combination of both the virtual space and their work books. All grade 3 students will have access to this program and already they are extremely engaged as they navigate the tools and space. This technology encourages problem based learning and is inherently mathematical but by creating virtual workstations the tasks become more explicit in nature. Also, by having small groups the students should develop a deeper understanding of the more abstract concepts. Within 30 minutes of using the program students from 3M & 3-O were sharing their newly acquired knowledge with other students in their group and this was wonderful to see. Lots of learning happening though they thought “the game” was hard but great fun!
