As you work through the number introduction lessons in this unit, you will notice they are all very similar in structure. This is purposeful. Kindergarten students thrive on structure, especially early in the school year. Also, I consider the demand of ongoing change on young learners. When there is a structure/routine in place, the students' stamina and focus can be used appropriately in tackling the learning content, rather than the learning structure (even if they are fun and exciting changes).
I like to keep these lessons very predictable and change and alter them only slightly so they become comfortable and confident in their routines. This lesson included a short, repetitive song for the children to sing. The students enjoyed the song and it has become part of our classroom 'repertoire" This was a fun add-on that did not disrupt the structure of the lesson so the students could move through it quickly and confidently.
