๐ Introduction to Data Collection with Tally Marks
This lesson plan provides a fun and engaging way to introduce kindergarten students to data collection using tally marks. By the end of this lesson, students will be able to collect data, represent it using tally marks, and interpret the results.
๐ฏ Objectives
- ๐ฑ Students will be able to identify and count objects.
- โ๏ธ Students will be able to represent data using tally marks.
