In Part 4 of Enough with the Seashells, Sid and his classmates reflect on their estimation investigation. The students explain that they first took out ten of the objects from their jar, observed them to determine how much of their jar those objects took up and then made a guess about the whole jar.
In Part 6 of Enough with the Seashells, a music video explains that though there seem to be an infinite number of stars in the sky or jelly beans in a large jar, estimation can help you to quantify the amount.
In Part 7 of Enough with the Seashells, Sid's Grandma tells him about how she once won a contest for estimating the number of jelly beans in a jar at a candy shop. Later, at dinner, each person in the family guesses the number of meatballs in the pot and then they count to determine the actual number.
