Building a tree stand
Problem Solving/Holistic Lesson Plan
Building a Tree Stand or Tree House
Aim: Students will discover the importance that geometry has
in their everyday lives and apply geometry to their lives.
Level Goal: Students will recognize how angles and shapes are used in
the creation of buildings. Students
will be able to see what angles work the best to support the most weight.
Students will also see what shape is the best for creating their platform
and roof over their head in their models.
Level: Middle School and High
Students will evaluate each others tree stands or tree houses and
determine which stand they would purchase.
will compare and contrast the differences of each others and provide their
classmates with feedback on how to improve their product.
Students will work
together in groups and be encouraged to be creative in creating their tree house
or tree stand.
They will be able to
decorate or camouflage their stand or house in any way that they choose.
Role play - salesmanship.
Students will develop a
model that they will present to the class.
The students will then have to prepare a presentation as if they where
trying to sell their product to the class.
Students will have to
convince their classmates that the product they developed is worth their
Students are to design and
build a model of either a tree stand or tree house.
The students will then give a presentation to the class, trying to sell
their model to the rest of the class. The
students will also then write a one page paper describing which tree house or
tree stand they would buy and explaining why without choosing their own.
Students will choose what type of tree they will build their tree stand
or tree house in and bring in a branch from that particular type of tree.
Students must have some type of ladder that reaches from the ground to
the tree house or tree stand.
Their tree house or tree stand must contain a roof over the top to
prevent inclement weather from coming in.
Students must record and keep a budget for their tree stand or tree
Tree stand or tree house must be able to hold at least 3 members of their
Scale of one inch equaling one foot will be used.
Students will work in groups of 3 or 4.
Students will use toothpicks to represent (2 X 4)‘s.
Costing one dollar per (2 X 4).
Students will use popsicle sticks to represent steel pipes used.
Costing five dollars per popsicle stick.
Students will use glue to represent nails.
Costing three dollars per three ounce glue bottle.
Students will use string to represent any rope used costing twenty-five
cents per inch of string.
Students will use paint to decorate their tree house or tree stand.
A one ounce bottle of paint will represent one gallon and cost seven
All materials purchased after the initial buying period will cost 20%
more than the original selling cost.
Students will have to determine their selling price.
Students will develop and use the following skills.
Work together in groups.
Follow set guidelines.
Create a budget that they used in their creation.
Presentation to their classmates.
Recognize how geometry is part of their lives.
Statement: Students will build
either a tree house or tree stand that they may build themselves in their
ordinary lives. Students will then
see and understand how geometry is part of the building process.
Responsibilities: The teacher
is to let students know how much time they have to finish their project, make
their presentation and when they will have to have their project completed by.
Responsibilities: Students will
be responsible for working with their classmates in their group, to build their
model and present it to the class. Students
will also be responsible for handing in a report about their own creation and a
classmates that they would wish to buy and what price they would pay for it.
Procedures: Prior to the project, students will be given a brief over
view of what they are to construct and pick their group members that will
contain similar interest. At this
time they will also be told about presenting their creation to the class and how
they will want to persuade their classmates to buy their model.
The students will then have to determine what tree they will build their
model in and collect a branch of that tree outside of class.
The students will then be given the parameters to develop their tree
stand or tree house and the students will have to brainstorm and determine what
products they will need to buy for their creation.
The next class session will then be spent building and developing their
tree stand or tree house. Another
day will be given for students to make final adjustments and to put together
their presentations. The students
will then present their materials to the class and make their selling pitch.
After all the presentation are made, students will be given time out of
class to write their reports about their own creation and the model that they
would wish to purchase.
Evaluation: Students will be graded on:
Ability to follow conditions and parameters.
Presentation to the class.
Report providing cost, materials, time spent on project, what it is meant
Report of picking a classmates tree stand or tree house and why they
choose that particular model.
Students will determine the start up cost and what their profit would be
if they went into business selling their tree stand or tree house to the public.
Students can build a real life tree stand or tree house.
Students can create a model of their tree house or tree stand on a
