Here’s one activity from additional classes in the fourth grade.
Activity: Students get a task to listen carefully to a description of a creature. They have to draw what they hear. After they finish drawing, students have to make a story and „bring their creature to life“.
Result: Besides having fun, students revise parts of the body, shapes, colours, present tense and vocabulary. They end up laughing at their creatures and stories not realising that they are making comparisons and still working on their English.
Try this and have fun right now!
