Parents Need to Know

Parents need to know that Questimate! is a remarkably unique math-estimation game that directly involves kids in making word problems with just enough guidance to keep the problems relevant and challenging. Estimating everything from how many bread loaves equals the length of the average couch to how far a hippo can run in a minute, kids get to combine various topics with types of estimation (length, speed, height, and more) via a fill-in-the-blank template with real-world options provided by the app. Kids earn points, hints, and power-ups to add some twists to the gameplay. Kids can play solo, as a pass-and-play game with a friend, or over the internet via Apple's Game Center. Questimate! is a major winner for engaging kids in the art of estimation.

Engagement, Approach, Support


Highly engaging. Kids are involved in both the question-formation and the question-answering processes. They can provide thumbs-up or -down feedback on questions and can take a poll to help develop more games within the app.

Learning Approach

Kids learn about and practice estimation firsthand by creating questions. They use a template that has a fill-in-the-blank form from which they select from preset real-world options to make their questions.


Clear instructions and preloaded choices. If kids' estimations are too far off, they're offered a retry or can completely move on. Tap the "Really?!" tab to view a detailed, mathematical explanation.

Kids will learn everyday problem-solving skills about estimating, which can transfer well into the real world. They can practice forming questions about estimation and then answer them. As players participate in creating the questions and then attempt to estimate the answers, they must recall information about these objects and apply logical-reasoning and critical-thinking skills. In the process of playing Questimate!, kids learn about part-whole relationships as well as the art of estimation, a helpful skill throughout life.

What's it about?

Kids start by choosing Solo, Pass & Play, or Game Center-based gameplay. Then they choose a quest: Intro or Need for Speed (the Amazing Animals and History of Awesome modes need to be unlocked with earned or purchased coins). Next they make a question, based on the options provided. For example, "How many microwave ovens would be as tall as the average couch?" or "How many bars of soap would be as long as a yoga mat?" Players answer but lose a life if the answer is too far off. Kids can tap "Really?!" for more information or move on to creating the next question. QUESTIMATE! provides excellent estimation practice.

Is it any good?


It's hard to overestimate how good Questimate! is for getting kids excited about an everyday math skill. The app is innovative, easy to learn, beautiful, and full of fun math-estimation practice, and many kids will return time and again. Generally for mid-elementary to early-middle-school-age kids, Questimate! empowers kids to get involved in both the question-formation and the question-answering processes. For kids to whom estimation doesn't come naturally, there's also a built-in control for errors: If kids' estimations are too far off, they're offered a retry, or they can completely move on, limiting frustration. Also, if they want to know why the answer is what it is, they can tap the "Really?!" tab and view a detailed, mathmatical explanation with photos. Kids also can rate the question with a thumbs-up or thumbs-down. Questimate! is a great-looking, fully engaging math-app experience from question to answer.

Families can talk about...

  • Practice estimation in everyday life for things like size, time, and weight.

  • Play the Pass & Play version of the game with your kids.
