Past Chicago vs MathStride

You know the street. You might not recognize the photograph. Past Chicago puts thousands of historic photographs on a map of the city. Start with your neighborhood, follow the lakefront, or wander through the Loop. Tap a place to see its buildings and street scenes from years gone by. Stop by Riverview Park or explore the 1893 World's Fair. Some places are instantly recognizable; others might have you checking the street signs. Find your own way through the collection: - Search for places and addresses, or use Locate Me to see what's nearby. - Filter by year to explore a different era, then browse the available photographs at each location. - Open a photograph full screen, swipe through the gallery, and zoom in for a closer look. - Save places you'd like to revisit. There's a little motion, too: watch a silent 1897 street scene filmed at State and Madison, right on the map where it happened. Every photograph includes its archive source, credit and available date information. Open the original archive record to keep looking. Approximate locations are labeled, with notes to help make sense of streets and addresses that have changed. The entire collection is free. No ads, subscriptions or in-app purchases. Made for iPhone and iPad. Location permission is optional, so you can explore Chicago from anywhere.

MathStride is math practice that finally feels like math class — you write your answers by hand, right on the screen, with a finger or Apple Pencil. Every solved problem is a stride. Tell MathStride the grade and what to work on, and it builds practice sets that fit — from counting to calculus. Each answer is checked as soon as you submit it, and progress builds toward the skills you chose. No printing, no busywork, no ads. HOW IT WORKS • Pick skills — describe the learner and get a grade-fitted list of skills to work toward. Optionally focus on your state's program (Common Core, California, New York, Texas) and add advanced AP-style topics. • Solve on screen — problems appear one at a time. Write the answer the way you would on paper; submit and keep moving while checking happens in the background. • See real progress — per-problem results, a walkthrough of every answer after each set, and a goal that completes when the skills are mastered. FOR PARENTS MathStride is set up and owned by an adult; a child practices under your account and supervision. Answers written on screen are processed to check them and never stored. You can delete the account — and all its data — any time, right in the app. FREE AND PLUS Every account includes 3 free practice sets per month. MathStride Plus gives 50 sets per month. Independently created educational software — not affiliated with, sponsored by, or endorsed by any standards organization or exam program. — Subscription — MathStride Plus is an auto-renewing monthly subscription ($9.99/month) that gives 50 practice sets per month. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period.
