FarmyardTask 72 ... Years 2  7SummaryStudents are asked to construct a plan view of a farm and divide it into paddocks of identical size and shape. This spatial problem, the second part of which is considerably more difficult than the first, then bridges into perimeter and area questions, which can also be related to pattern and algebra, and value relations challenges.

IcebergA task is the tip of a learning iceberg. There is always more to a task than is recorded on the card. 
The solution to Question 1 is straightforward and offers the students early success. The second question may need a hint. If so, you might suggest dividing each square of the Trisquare into 4 smaller squares and removing sticks until there are only 8 left in the middle. Another approach might be to ask if the students could make a smaller Trisquare with yellow sticks. Extensions Value Relations

Whole Class InvestigationTasks are an invitation for two students to work like a mathematician. Tasks can also be modified to become whole class investigations which model how a mathematician works. 
To use the initial task as a whole class investigation, you only need sticks and dot paper. Matches or pop sticks will work, as will any number of things from the art room. To use the extensions to the full it is probably best to have a set of Trisquares. Of course, part of the investigation could be for the kids to make a class set of cardboard Trisquares. At this stage, Farmyard does not have a matching lesson on Maths300. However, lessons with related content include Sphinx & What's It Worth?. For more information on either of these investigations, open a new browser tab (or page) and visit Maths300 Lesson 25, Sphinx and Maths300 Lesson 99, What's It Worth?. 
Is it in Maths With Attitude?Maths With Attitude is a set of handson learning kits available from Years 310 which structure the use of tasks and whole class investigations into a week by week planner. 
Farmyard is not in any MWA kit. However it can be used to enrich the Chance & Measurement kit at Years 5/6 and Pattern & Algebra Years 7/8.
