Production - here the students learn how to use the language
Here the teacher asks them to apply the language that they have previously learned to some part of their life. Here he asks them "Who can ride a bike?" and other questions related to the phrases that they already practiced.
In production the students should find a way to use the language. It's important that they can find a way to use the language in a way that can be applied to their life. In another example you could have them write down what they can do and maybe have them draw a picture too. The drawing would work well for young learners.
