ProblemMs Tina drove to the store to purchase toilet paper. She purchased 12 rolls and returned home. She discovered that the toilet paper rolls did not have a center hole.
The problem with this was that she could not place the rolls on her dispencer.

In pairs, design 2 containers to hold and dispense 1 toilet roll each.
Process orderThink, plan, measure, design, test, construct prototype, test, (redesign if needed, test) construct final product.Helpful hints
● Spend time planning your nets on paper.● Check measurements of toilet roll.● Ensure your net will completely encase the toilet roll.● Ensure your net will allow for a replacement toilet roll.● Practice your net using paper first.● Make any adjustments, plan decorations and prepare prototype net for
copying.● Construct final net from prototype.● Decorate your final net before constructing it.● Test your product with the toilet roll.● Present your product to the class.
Be creative when naming your final product.
Design Challenge

Students will;● Apply their knowledge of geometrical skills to solve a problem.
o Calculate and use PIo Calculate circumference and area of a circle.o Measure and design a net to size.
● Apply their ideas and creativity to solve a problem.o Work collaboratively with others sharing ideaso Support others with issues such as remembering formulas.o Plan and build prototypeso Demonstrate pride when showing off the final design

Success Criteria
Students have:● Produced a product that solves the problem.● Reflected on their process.● Recorded planning (including calculations &
prototype net plans).

The Process - Measure
Students measured the circumference and area of the roll using a range of equipment.
Which tool should I use to measure the circumference and area of this roll?
Which formula do I use?
Circumference = π x d or π x r x 2
and Area = π x r2

Students applied their knowledge of formulas to calculate area and volume for the size of their construction.
The Process - Calculate
Let’s check our calculations with a calculator!

Students brainstormed ideas for containers before developing nets
The Process - Brainstorm Hmmmmmmm
Do you think this shape will work?
What if we rolled it like this…?
![Page 9: Toilet Paper Net Challenge 5TC Solving Real Life Problems.](https://reader037.fdocuments.net/reader037/viewer/2022103007/56649e2e5503460f94b1e819/html5/thumbnails/9.jpg)
The Process - Collaborate
Students collaborated on the design for the product.
How about we...
What about if we did this…?
Could we try doing this…?

Students checked their calculations of the net designs
The Process - CalculationIf PI is 3.14 and to
get the area I have to multiply radius x
radius then the formula should be
π x r2
“But isn’t the formula for finding the area of a circle π x d?”“Ah… I don’t think so, isn’t it π x r2?”

Students started making their nets for their dispenser prototype.
The Process - Prototypes
If we join multiple sheets of paper together we can draw our net in one go.

Students began constructing their prototype containers. But there was a problem… Some constructions were being made with individual pieces of paper and not nets
The Process - Construction

What is a net again? Ms Tina pulled apart a tissue box net

Final Products
My favourite part of the challenge was creating and decorating the product. Meet Chompy!
Creating this product was challenging. Getting the shape and measurements correct was difficult.
