The learning method is the key to successful learning.
It is recommended that you give out only 5-10 cards each time, and have your child watch each animation at least 3 times. Encourage your child to speak, and use the recording function to record the output.
When your child asks for new cards, use the “Flash” feature to enhance his/her memory, and then use the “Test” function to make sure he/she has mastered the current set before giving out another 5-10 cards. This learning process is more challenging and motivating.
