ETL216 - Assignment 1- Elyse Weir - Sem 2, 2012Slide2

When I first thought about a teaching aid that would help children to understand area, I considered creating squared metres out of: ● brown butcher paper● newspaper● pipe

Early Ideas..

As the design brief stated, the artefact must include two recycled items and have a moving part. This meant I needed to progress from these ideas to include a moving part in my design . I had a specific topic I wanted to concentrate on, in measuring area and thought my ideas were on the right track. So, I began discussing my thoughts and ideas with my family and some of the staff at the local hardware shop.

Early Ideas continued..Slide4

InspirationAs seen in earlier slides, I had my own ideas about what material could be used to create the metre square measuring object. I practiced this concept of using a squared metre to teach area in a year 5 class and we used straws and masking tape to create

our squared metres. After exercising this in the classroom I thought about how I could use this idea but tweak the materials to fit with the design brief. I thought

about using some kind of wood to create the squared

metre as it would be sturdy and hold its shape and would be strong enough to drill through/attach a hinge or bracket to create the moving part.

Timber - recycled from door stops on some old door frames. I used 7 lengths of the timber and had to sand it back and putty up the nail holes. Recycled MaterialsSlide6

TOOLS METHODPencilMeasuring tape

Circular saw

Drill

Sandpaper

PuttyNewspaperRopeBlack permanent texta

1.) To achieve 7 equal 1m lengths of timber, measure the wood and mark where cuts are needed. 2). Saw the timber to have 7 equal lengths. 3). Put the timber in a square on the floor and mark where the screws need drilling in.

4). Drill 5 holes in the timber.5). Putty up the nail holes and sand timber back.6). Spray paint the timber and screws over newspaper and raised on rope.

Wait to dry. Give 2nd coat.

7). Attach lengths together with screws while on ground and write 1m along each side.Slide8

Prototype This design was first used in a classroom and was created from straws. This tested the design as to whether it was an effective teaching aid.

It proved to be a hit with children and in turn an understanding of area resulted.

The construction of these basic designs presented a few minor problems to improve when planning the final design.Slide9

Problem Solving from in Class TestingThe design worked well in the classroom over a series of lessons with a metre square straw shape, but to fit the design brief a few changes and problems needed to be addressed.

The material needed to be strong and hardy to withstand multiple use and weather factors.

Some part of the design had to move. I thought about hinging a second metre square to the first.

The artefact should be easily transported. Slide10

□ The idea of building a solid square frame changed to include corners that had movement.□ This completely changed the capability of the artefact because this meant the design: - Had a range of movement

- Could be folded up for easy transportation/storage

- Could create a squared metre to measure area but also a straight line to measure distance/perimeter.

Construction & AdjustmentSlide11

Attributes:- Measures area & perimeter - Durable - Attractive - Easy to transport - Easy to store - Made from some recycled materials - Moving parts - Engages children Presentation of Design
