Arty Shapes

Achievement Objectives:

Achievement Objective: Sort objects by their appearance.

Purpose: 

In this unit students take inspiration from several cubist artists then participate in a variety of art based activities to develop their knowledge of 2-dimensional shapes. They use their own language to describe their works and the shapes they have used.

Specific Learning Outcomes: 

name 2-dimensional shapes: triangle, square, oblong (non-square rectangle), circle, oval, pentagon, hexagon and diamond

describe shape attributes in their own language

Description of mathematics: 

This unit begins an exploration of basic 2D shapes, their properties and the mathematical language associated with them. There is a progression from the way the students think of and see these objects to the more formal mathematical ideas and descriptions. In order to be able to communicate on any topic, there is a need for a common language. This unit takes the initial steps in the formulation of this language for the students.

As students progress through the curriculum levels, they will continually meet geometric objects and need to use them in ever more sophisticated ways. This later involvement with geometric objects will rely heavily on a sound base of both language and concept that is established in units such as this.

Required Resource Materials: 
Session One: Black paper, colour copies of the Shape Sheet in a variety of sizes, scissors,glue
Session Two: Paper for each student, shallow containers of PVA glue, paint or food colouring to colour PVA (optional), string of
Session Three: Paper for each student, large stencils made of thick card in a variety of shapes, crayons and dye.
Session Four: Salt, flour and water to make salt dough, rolling pins, biscuit cutters in a variety of shapes, drinking straws, coat hangers or similar to hang shapes from, access to an oven to dry salt dough shapes, paint and string.
Activity: 

Begin each session by looking at one or more of the art works in the cubist style. Have students identify the shapes they can see and describe these.

What shapes has the artist used in their painting?
Can you see where the artist has used corners?
Where are the straight lines in this art work?
How would you describe the shapes the artist has used?
In what ways are the shapes the artist has used similar? Different?

As you look at the work of each painter tell the students a little about their life.

Throughout each session encourage the students to talk about what they are making and the features of the shapes they are using. Discuss the similarities and differences in shapes and encourage a wide use of a range of terms. Counting the numbers of sides and the numbers of corners each shape has is also a good way to get students to focus on shapes.

Terms: sides, corners, curved and straight lines, edges, pointed

Questions to use:

Do you see any ways that these shapes that are alike? How are they alike?
Can you see any shapes that are different? How are they different?

What do these shapes have in common?

What are some of the things you notice about the shapes you are using?
Do you know what we call these shapes?

What can you tell me about that shape?

Why have you chosen to use that shape?

Are all the sides the same? Are all the corners the same?

Session One: Shape Collage

  1. Provide students with one sheet of black paper each, a variety of shapes in different sizes and a pair of scissors.

  2. Have students colour in and cut out a variety of shapes and arrange them in interesting ways to make a picture, this may be abstract or a familiar object such as a car or a person.

  3. Encourage students to discuss their work and the works of others’ and to change their designs as their ideas develop.

  4. Once they are satisfied with their pictures, students glue the shapes in place.

Session Two: String Shapes with PVA

  1. Provide each student with a sheet of paper, strings of varying lengths and access to a shallow container of PVA. PVA may be coloured using food colouring or paint if desired.

  2. Students dip pieces of string into the PVA and place them onto their pictures, making a variety of shapes in their work.

  3. Encourage students to discuss their work and the works of others’ and to change their designs as their ideas develop.

  4. Once designs are dry they can be use as a block to create crayon rubbings if desired.

Session Three: Shape Stencils in Crayon and Dye

  1. Provide each student with a piece of paper, some large stencils made of thick card in a variety of shapes and some crayons.

  2. Students trace around the stencils in a variety of different colour crayons, overlapping shapes to create an interesting effect.

  3. Encourage students to discuss their work and the works of others’.

  4. When shapes are complete students can paint over shapes with dye to enhance their work.

Session Four: Shape Mobiles

  1. Mix salt dough using equal quantities of salt and flour with enough water to form dough with good consistency.

  2. Provide students with dough and cutters.

  3. Students flatten dough using rolling pins and cut a variety of shapes using biscuit cutters. Each shape needs a hole at the top to enable it to be hung with string. This can be made using a small piece of drinking straw.

  4. Encourage students to discuss their work and the works of others’.

  5. Place shapes in the oven at 100ºC for 1 - 2 hours out dry out.

  6. Once shapes are dry they can be painted and hung onto a coat hanger with string to create a mobile.

Session Five:

In this session students reflect on one of their art works made in the previous sessions, discuss and describe it and write about their work.

Their writing could then be published and displayed, either in a classroom display or in a large book for the book corner.

Shapes With Sticks

In this unit students make and investigate a variety of three dimensional shapes. By examining a wide range of shapes and looking at the relationship between the numbers of faces, edges and vertices they see whether they can “discover” Euler’s famous formula.

This unit involves a lot of exploration with three dimensional shapes and would be ideal as a lead in to the unit Building with Triangles, a level four unit which goes on to look at a group of polyhedra, the platonic solids, in more detail.

Foil Fun

In this unit students will be having hands-on experiences with three-dimensional solid shapes. They will investigate the features of solid shapes and learn the names for them. They will be introduced to making nets for 3D shapes.

New Kids on the Block

This unit is suited to a small class at a school where large building blocks and wood off-cuts are readily available. Asking students to construct affords a prime time to observe them as they build and to listen to the mathematics they talk about. Using blocks is a powerful medium for improving students'’s perception of objects and encourages creativity.
