Ms. Barry taught a great lesson today! She helped kids practice their estimating, rounding, and counting skills - all while having fun!
Each table received one pumpkin. (Thanks to Volante Farms for generously donating the pumpkins!) The children worked together in table groups to estimate the number of seeds in their pumpkin. Together, the class rounded the estimates to the nearest ten. Then plotted the estimates on a number line.
Next, we got messy! Third graders dug into their pumpkins, pulling out the seeds. They developed different strategies to count the actual number of seeds inside. Many children counted by tens. They recorded the actual numbers on cards.
Finally, Ms. Barry led the children in rounding the actual numbers to the nearest ten. These new numbers were plotted on the number line.
Tomorrow, as we learn to subtract with regrouping - we will find the difference between the actual number and estimated number of seeds.
Happy Halloween! :o)
