Why can children learn on their own?
- Voice read out loud: The test has text read aloud in Vietnamese (and 12 other languages), so 5-6 year old children who are not fluent in reading can still understand the problem.
- The rabbit models first: the child sees the way of thinking in a small example, then does the real sentence.
- 3-step suggestion: Step 1 gently reminds, step 2 draws an illustration, step 3 gives the answer with explanation. Children only open the next step when they really need it.
- Review the wrong sentences:after the Practice Test, the child reviews each wrong sentence and which areas are weak.
