## Homeschooling with a 3D Printer – There are 100’s of ideas to make mathematics come to life.

If you haven’t yet invested in this brilliant tool, let me show you some easy ways to make homeschooling with a 3D printer come alive. **The secret is in solving real problems – its even better when there is a tangible object to create.** As a teacher – I see Maths applications with a 3D printer for ALL ages of kids – from the the little ones (where my daughter is) to the bigger ones who love the question – What’s the point of Maths? The beauty of homeschooling with a 3d printer is that you have the time and freedom to get your kids using Maths while creating and inventing.

##### Lets look at the Mathematics in designing a 3D model.

Starting in Google Sketch Up – It is super easy to create all of your basic geometric shapes.

Maths Task 1 – **Design a Cube/Pyramid/Sphere** you name it – with **X** dimensions. You now have a tangible model for the rest of your tasks. Everyone loves holding something.

Maths Task 2 – Put those formulas to good use! Work out the **area** of a face.

Maths Task 3 – Work out the **volume.**

**Here’s some Real Life Applications** –

- How much plastic would we use if we printed this item as a solid?
- How much would it
**cost**us in plastic? **Percentages –**How much plastic would we use if we printed this item as with a 10% or a 20% inflill (This is done in the slicing program)- What is the new cost in plastic?
- What’s the saving?
**Subtraction**

Maths Task 4 – **Scale – **Send them pack to Google Sketch Up to scale their item by 1.5 or 2. Print. Repeat the process.

**Extension – Real Life Application**

**Task – Create a product for sale on Etsy**

(Or select a cool item to print from Thingiverse like these Linklins)

- How much plastic does it use?
- What does it
**cost**in plastic? - How many of the items could you get out of a roll of filament?
**Division** - What price would it need to be if you have to make 30% profit?
**Percentages**

Throw in there a spreadsheet and extend your Maths lesson.

**What about extending it into an English lesson and create an advertisement for their model they want to sell.**

We love our 3D printer and we use all the time. Our little knows all her geometric solids and loves the items we have printed for counters, her Montessori Fraction Circles and her Montessori Pink tower. The high school teacher in me just knows that there will be many many more uses in the years to come as we do our homeschooling journey together.

I am blessed to have an engineer husband who built a DIY 3D Printer for us. After 3 months of struggling through with a lousy manual and little quality control – we decided that we’d love to sell the same printer. **Our heart was to enable homeschooling with a 3d printers affordable by doing lots of the pre-build for families. Our printers are almost plug and play so families can avoid the costs of commerical printers but still get the benefits of homeschooling with a 3D printer.**

Hopefully you can see that Maths is embedded into every aspect of 3D printing. You can build any Maths lesson around any or all of the stages in designing to printing. And its fun

Looks fantastic Mel! Are you going to home school?

Not much choice when we are living in Arnhem land I’d be happy to put Ashley in the local school except that the kids only turn up a couple of days in the week. She shouldn’t have to miss out. I love all the Montessori stuff. I’ve been making my own with the 3D printer. It’s brilliant!
