Students love birthdays! Our team decided on a special, simple way to recognize each child's birthday this year. We want to make every effort to recognize students' special days, interests, needs, and talents.
I'll focus a few math lessons at the start of the year on birthday math. It's a good way to get to know one another, practice math practices, and review concepts and vocabulary related to measurement, data, and statistics.
I invite you to use this lesson if you'd like.
- Decorate your birthday cake (above). First write your full name and birthdate in number form and word form in pencil. Then go over the pencil with a thin-line sharpie. After that decorate your cake using colored pencils and markers. (Make sure your birthdate and name show up clearly)
- Hang your birthday cake up in the correct place on the classroom birthday pictograph.
- Solve the birthday math problems on paper and/or with a calculator:
- How old are you in years? ______
- How old are you in days? _______ (365 days = one year, 366 days = one leap year list of leap years)
- How old are you in hours? (12 hours = one day) ___________
- How old are you in minutes? (60 minutes = one hour) _______
- How old are you in seconds? (60 seconds = one minute) _____
4. When the birthday pictograph is complete, make a bar graph that matches the pictograph, and then make a line plot that matches the pictograph. For the line plot use each month’s number.
5. Bonus: Make a line plot of the birthday numbers.
6. Write a short analysis of the birthday information about the grade-five team. What month has the most birthdays? What month has the least? Can you imagine reasons for more birthdays in some months than others? What else do you notice about the data?
