From the 3/4 Classrooms

Shapes!  Shapes! Shapes!

Term 3 has started with shapes! Grade 3 and 4 students have been rediscovering and learning more about shapes and 3-D objects. 

In classroom learning activities students have been identifying shapes and 3-D objects in the school environment. They have also made 3-D objects from nets and built them out of Polydron Shapes. In building 3-D objects they have identified the shapes that make them up and named their geometrical properties - how many faces, vertices and edges each object has. 

Some of the more interesting 3-D objects that have been made are pentagonal, hexagonal and octagonal prisms; hexagonal and octagonal based pyramids; dodecahedrons and tetradecahedrons! 

In the student work below on Pic Collage you will see some of the 3-D objects they have made!

In the coming weeks, students will be learning how to calculate the areas and perimeters of shapes, including both regular and irregular shapes (polygons). They will also be describing 2-D shapes that result from combining and splitting common shapes and they will learn to measure the internal angles of shapes using protractors!

Amongst the odd game of ‘Shape Bingo’ the students are engaged and learning a lot about shapes!!

If you have the opportunity, ask them what they know and see if they can identify 2-D and 3-D shapes in your home!
