Appearance and function match the final product, but is made with different manufacturing methods.

Looks like the final product, but is not functional.

Demonstrates the functionality of the final product, but looks different.

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

These photos and videos provide a detailed look at this project’s development.

Good news: the campaign over 100% funded and there is a stretch goal!

wonda is a math toy that improves memory recall for math process like multiplication and division. It is effective as an in-class teaching resource and as a practice tool outside the classroom.

Kids can practice with it even right before bed!

The top, middle and bottom pieces are designed to be assembled over each other and rotate very easily. There are labels that contain the numbers which are on the bottom piece.

Rotating the top piece selects a multiplier for the number and rotating the middle piece reveals the product. This process helps the child to 'guess' what the answer would be before revealing it.

This means every time a child learns the multiples for a new number, the difficulty level can change. Older numbers can be revisited.

Many pupils find math difficult to learn, and need to practice recall of concepts already taught in class.

Kids like to play, so I thought to myself: how could I make math more playful?

Many prototypes were tested with parents and teachers across Ontario, receiving rich feedback each time.
