What differences are there between Think!Think! compared with the general digital learning materials?

Think!Think! differs from many other apps which help you acquire skills and knowledge in subjects such as calculation. Think!Think! is an educational material with a core design that fosters "thinking sense" and "motivation to learn".

"Thinking sense" is a very important ability for effective learning. For example, a child with good "thinking sense" will realise that when learning multiplication and division, they are in fact "dealing with the same thing" but from a different angle. From this, the child will be able to independently grow rapidly. Furthermore, as we live in a generation where anything can be learned online, and rather inexpensively, there is a large difference in academic performance depending on one's level of motivation. Think!Think! fosters "thinking sense" along with "motivation to learn" by tackling high-quality puzzles and three-dimensional and graphic problems, all whilst having fun.

Can an app really give more power than paper?

Precisely because Think!Think! is an app, this educational material is able to take full of advantage of being digital and exceeds the limitations of paper based materials to ensure that anyone is able to improve their skills.

In order to develop thinking sense, for example, to "assemble a 3D shape mentally in one's head", it is necessary to have that ability as a sense. Think!Think! reproduces the sense that "a person with a good sense of thinking" has, and with movement, this enables anyone to visualize what was once difficult to understand on paper. This is an innovation in educational materials with thanks to the evolution of technology. In addition, by taking advantage of the merits of app based technology, such as the presentation of problems tailored to each person, "real time" feedback that suits the characteristics of young learners, and a system that appears to be a game on first glance, you can expect greater educational effects than paper based materials.

Of course, paper-based materials have their own merits. At Wonderfy, we believe that it is important to recognize the advantages of both paper-based and app-based educational materials. Given that, we have also created our "WonderBox" service, a STEAM education home learning material that combines analogue materials with digital learning. Please feel free to check it out.

Do you have any tips on how to use it in the most effective way?

We recommend talking with your child in a positive manner.

To develop critical thinking skills, your child needs to be able to say "I want to try it!" and "I can do it!". It's of utmost importance for your child to concentrate on the problem with the feeling of "I want to do it!". Forcing children to do things they don't want to do or with little interest in is not beneficial to their learning process and therefore will not bring out their full potentials. Focusing on your child's efforts and praising them by saying "That's amazing!", "You did a great job!", your child's motivation level will rise and will continue to improve. It doesn't have to be everyday. Even if your child only says "That was fun!" or "So annoying!", continue to encourage them in a positive manner.

I'm not good with critical thinking or STEAM subjects, so I have little confidence in my ability to teach them to children.

The strength of our app materials is that children can work on them totally by themselves. There's no requirement for a parent or guardian to explain anything.

Think!Think! is designed so that rules can be understood intuitively, and the problems are tailored to each child's individual level and thus, explanations from parents or guardians are not necessary. Should your child have a hard time with a particular question, you can guide them towards the "hint" button on the screen.
Each time your children solves a puzzle, they can see a real time representation on the screen. For example, how a 3D object is cut to make a cross-section, or how a net is assembled. Even if at first, the concept is difficult to understand, they will gradually be able to visualize abstract ideas and concepts in their head by themself.
If you're a parent or guardian, please encourage your children's efforts by saying "That's great! Keep trying!".

Can it be used for free?

Yes, it can be used free of charge.

You can use the free course for 1 play (3 minutes) per day. You will not be automatically converted to a paid course unless you subscribe to a paid course or sign up for a free trial.

Yes! All you need to do is make a note of your Account ID and Device Number from the Settings section in the Grown Up's area of the app. Tap the ‘Restore Data’ button on the start screen of the app on a new device and then just enter your details to restore your progress.
