# Summary of Unit of Work:

The focus of this unit is to apply measurement concepts within a real life scenario. Students design their own dream house while using many mathematical and design processes with the final outcome being a complete house design with all costing included. The unit draws on both mathematical and design concepts such as measuring, predicting, estimating, calculating, designing, communicating, problem solving, generating ideas and communicating with others. Students will learn the processes and skills involved in house design.
