On Monday we explored and talked about another kind of community graph; our birthdays!
Our birthday calendar invited conversation about how every month in a year is a number; 1-12. With this new learning, I don't expect all children to say what number the month of October is, but I do expect them to be able to find it on our birthday calendar and use our recently added labels.
When sharing noticings about our birthday calendar, children were quick to fill our calendar with their observations and labels. We noticed the title (Our Birthdays) and the names of the months. We noticed the little circles of wood hanging under each month.
We talked about birthdays and counted how many Kindergarten students had a birthday in each month. We compared amounts using the words most, least, and equal. Following our conversation and the labeling of our birthday calendar, children used lines and dots to decorate their little birthday sign.
Counting the number of birthdays in each month and counting how many birthdays in all is an example of students working on an essential standard; touching and saying a number name for each object and counting objects in a line. The children can point to and count the round birthday signs we decorated.
Later in the week, when Helen was printing the date on our morning message, she modeled how we can use our birthday calendar to figure out how to write the date. If October is the 10th month, our date starts with 10.
We can count objects in a line and we can count objects in a group!
We have continued our work with lines and dots through the math read aloud 10 Black Dots by Donald Crews. Following the read aloud, children counted out their own 10 black dots and thought of something they could create with 10 dots. First they thought of and shared their plan. Next they counted to make sure that they had 10 black dots. Then they drew their picture and glued down their dots. Finally they had to check their counting again!
What can you make with 10 black dots?
