Askî’s Pond is an iPad math game for Grade 1 students, featuring the characters from Askî’s world. The game reinforces Saskatchewan curriculum math outcomes and processes and is available in the iTunes app store (free of charge) for all school divisions and First Nations Education Organizations. Search for “Aski’s Pond” or “Aski.”
Askî’s Pond supports math improvement and connects directly to the reading, writing and math and the First Nations, Métis and Inuit engagement outcomes. The game integrates mathematics and First Nations and Métis content, supports math instruction in the classroom and, like Help Me Tell My Story, is a wonderful family engagement tool.
The game can be played in either English or French.

The inspiration for this site came from John Allen Paulos' book Innumeracy. From it Fawn Nguyen took the mathematical fun facts, etc. and created middle school mathematics critical thinking problems that relate to ratios and proportional reasoning and require students to compare stuff and really get them thinking.

Here's an example:
Tortoises have the longest lifespan among vertebrates, about 200 years.

A fruit fly's lifespan is about 45 days.
​
If we scaled both lifespans down so that a tortoise's 200 years is now 1 day, then what is the fruit fly's lifespan, in seconds?
