TK Math Instruction Videos

In transitional kindergarten, children learn important foundations of mathematics through hands-on interactive learning, with many opportunities to practice new skills and learn. Preschool California has partnered with Long Beach Unified School District to develop instruction videos that demonstrate what mathematics lessons in TK might include. Our thanks to Superintendent Steinhauser and the team of educators at Long Beach Unified School District for opening up their classrooms and sharing their efforts with the TK community.

This is a series of three videos demonstrating complete math lessons in a TK classroom. All three videos focus around using students names in the math lessons. 


In this math lesson, a small group of transitional kindergarten children are adding the number of letters in students’ names while practicing turn-taking, cooperative learning and problem solving.

The teacher’s objective is to observe students and assess their ability to work independently or with a partner, and differentiate instruction based on her observations. Student understanding of math concepts taught in previous small group instruction is essential for them to successfully practice independently in the math work area.

The lesson concludes with a transition song, still focusing on students’ names, but emphasizing the position of letters.


In this math lesson, a small group of transitional kindergarten children are learning to sort and categorize numbers using the number of letters in students' names, while practicing turn-taking, cooperative learning and problem solving.

The teacher's objective is to work slowly with this group, and assess and support when the group can move with confidence to the next skill level.


In this math lesson, all children in the transitional kindergarten class provide information for one graphing chart. The children successfully develop a class chart, however the columns were not quite wide enough for all the names. The teacher recommends a bigger chart with bold lines so that students can see all data through clearly differentiated columns, an important aspect of teaching graphing.

The lesson closes with a jumping rope activity, integrating gross motor activities into a math lesson that transitions smoothly into recess. The teacher picks three names randomly, and these children get to choose a "jumping number." The children are encouraged to jump rope to the number they pick or beyond.
