This lesson is an interactive way to teach students how and why graphs are used. This lesson is fun for the kids and they get to learn about their classmates birthdays.

Students will sort themselves according to birth date. Students will graph the number of birthdays within each month and determine what information the graph provides (e.g. which month has the most, which has the least, and which (if any) has the same number of birthdays).
Students have already been introduced to sorting and graphing. A lesson on sorting students according to hair color, eye color, and gender precedes this lesson.
Students will gather and sit on the carpet area. Students will be asked if they know when their birthday is. They will then be asked if they think they share the same birthday with someone else in the classroom. They will then be asked if they think they share the same month as someone else in the classroom. As a group, we will briefly discuss that it is more likely that two people will share the same birth month rather than an actual birthday. The students will then be given instructions for the acitivity. Students will write their first names on a strip of paper. Large cards will be placed on the floor in the classroom. Each card will have the name of a month (pictures could also be added to help students identify the months-ex. a clover for March). The students will be directed to find the card with the name of the month they were born in and form a line behind it. Once the students have found their particular birth month, the students will be directed to count the number of students in the line they are in. The students will then be directed to look at the number of people in other months. On the dry-erase board at the front of the classroom, a graph will be present. The “x” axis will have numbers 1-10 and the “y” axis will have the name of each month in order from January to December. Once prompted, each group will be called up to the board. With teacher assistance, each student will place their name (written on a strip of paper) in the column of their month. Once completed, the students will be asked what the graph tells us. The students should be able to recognize that the graph reveals which month(s) has the most bithdays, which month(s) has the least number of birthdays, and which months have the same number of birthdays (if any). As a group, we will check our answers by counting the number of names for each month to accurately determine which month has the most, the least or the same number of birthdays. Students will then be directed to ask members in their month to determine if any share the same birthdate. In closing, students will be asked to share what they learned about using a graph.
Students will work collaboratively & individually.
1 class period. 30 Min. per class.
  • Materials and resources:
    Twelve large cards with the names of the months and dry-erase/chalkboard
Strips of paper
• Subject : Mathematics
• Subject/ Grade/ Domain : KINDERGARTEN
Data Analysis, Probability, and Discrete Mathematics
Every student should understand and use all concepts and skills from the previous grade levels. The standards are designed so that new learning builds on preceding skills and are needed to learn new skills. Communication, Problem-solving, Reasoning & Proof, Connections, and Representation are the process standards that are embedded throughout the teaching and learning of mathematical strands.
Data Analysis (Statistics)
Understand and apply data collection, organization and representation to analyze and sort data.
Formulate questions based on data displayed in graphs, charts, and tables.
Students will be assessed acording to their participation, understanding of what is taking place, and their ability to follow directions throughout the group activity.
