# Good apps on the iPad for inquiry-based exploration in a quantitative reasoning course

I'm teaching a quantitative reasoning course at a two-year community college and I'm endeavoring to be as inquiry-based as possible in my teaching. We have access to class sets of iPads, and I'd like to use them in a few class sessions, but I need to find the right apps. I'm looking for apps that do something like the Tile Pile exercise on proportional reasoning over at Desmos.

I've seen a few apps that are basically textbooks with interactive problems, and a few other apps that are just exercises disguised as games. What I really want is an app that allows students to explore the concepts on their own. The Tile Pile example is really perfect in this regard.

Here is a list of different topics I'll be covering to help you suggest different apps.

• Proportional reasoning (ratios, percentages, rates)
• Number Sense (place value, scientific notation, rounding, understanding big numbers)
• Graphs and charts (creating, interpreting, and analyzing)
• Inequalities
• I'm teaching OCR quantative reasoning course this year. 16 year old C grade GCSE and would also be interested in ideas for explorative learning. Especially transparent tasks that have clearly identifiable goals and that are not frustrating.

• This is not an app, but you may want to take a look at Mathalicious (mathalicious.com). It has a lot of pretty awesome lessons that need minor tweaking to do anything you want them to do. Additionally, you could use stuff from Dan Meyer's 3Acts stuff (docs.google.com/spreadsheet/…). That is also a lot of inquiry/applied math and some of it fits under the categories you have described (then use things like Desmos to do work). Commented Oct 4, 2015 at 5:39
• @Joey Kramer a very useful resource thanks

• iPads are expensive. Better look for stuff that runs on a generic Android tablet and/or a not-so-high-end smartphone, or can be used over the 'net from those devices. As a bonus, the later ones will work with the iPad too ;-) Commented Jan 17, 2016 at 21:41
• @vonvrand an iPad is not nearly as expensive as a year's worth of textbooks, and can be used over the course of several years. As a student and a teacher, my iPad is invaluable. Commented Jan 18, 2016 at 0:22
