Number Pyramid is a math puzzle for kids — and anyone who likes numbers. Some boxes in the pyramid show a number; the rest are blank. Each box is made from the two boxes beneath it — their sum in the early grades, their product later on. Use what you know to work out the rest. A preset for each grade from Kindergarten to Grade 6 follows the school curriculum: numbers to 10 in Kindergarten, adding and subtracting up to 10,000 by Grade 4, then multiplication in Grade 5 and division in Grade 6. Kids play at their own pace. Hints walk them through any box they're stuck on, one step at a time, and a scratchpad is there for working the math by hand. Free: Kindergarten, Grade 1 and Grade 2, with hints, scratchpad, and progress tracking. One purchase unlocks everything else, for the whole family: Grades 3 to 6, up to six player profiles, Time Challenge — a race against the clock with rising levels, in add/subtract or multiply/divide mode — and custom difficulty (pyramid height, number size, operators, negative numbers). No data collected. No ads, no tracking. Works offline. ## Key features - Grade-based math curriculum (K-6) - Sum and product puzzles - Hints and scratchpad - Progress tracking - Offline play - Time Challenge mode - Customizable difficulty ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Full Version | $2.99 | one-time | ## Recent user reviews (5 of 5) All indexed reviews: https://appshunter.io/ios/app/number-pyramid/id439569968/reviews.md ### 5/5 — A "great" app. *2012-03-19* This is a must have addition or subtraction skill builder. It can start with simple problems for a 4 year old and ramp up to more challenging problems if the teacher wants to do that. Fun and educational at the same time. Great, and worth the $0.99. ### 4/5 — Great app *2011-11-25* Doesn't get a 5 because can't save the level when you stop. Really like that the level can be changed. Has crashed recently too. ### 5/5 — Great but crashes *2011-09-21* As a math teacher I love the way it helps students practice mental math (adding and subtracting in their heads.) Lately the app has crashed a lot and needs the bug fixed. Otherwise I highly recommend it! ### 5/5 — Great educational experiance *2011-06-24* Very useful ### 5/5 — Fun educational tool *2011-06-10* This is a nice and fun tool that helps strengthen basic arithmetics skills. I evaluated the app for my kids and ended up liking it so much i'm playing with it myself. It's a learning tool but it plays like a game! ## Frequently asked questions about Number Pyramid ### What math skills does Number Pyramid teach?
