“Can” you believe it?
Today we read Sir Cumference and the First Round Table - a Math Adventure by Cindy Newschwander, illustrated by Wayne Geehan. In the story, the king had a problem because he was tired of shouting across the table for meetings and he had developed a sore throat. So, his friend Sir Cumference, his wife Di from Ameter, and their son Radius worked on a problem of redesigning his table. As the story progressed, they try different shapes and decide on making a round table. This way, the knights and the king can all fit around the table comfortably. This book introduced the terms: diameter (a line that passes through the center of a circle and has endpoints on the edge of the circle), radius (a line segment that begins at the center and extends to the edge of the circle), and circumference (all the way around the circle). We practiced making circles with a paper clip as our tool, labeling the diameter, radius, and circumference. From this we wondered…what would have the greatest dimension, the height or the circumference of various cans? So, we looked at several, made predictions, and then actually measured the cans. Boy, were we surprised! Most cans have a greater circumference than height! Who knew!

I didn’t think the circumference was going to be greater then
the hight but it was ,and it was a little hard!

that was so fun and cool but i got only 2 of the questions right i least exspected for the circumference to be bigger than the height!!!! Also i did learn alot from that!!!!!!!!!!

Now that I know what circumference, diameter, and radius means, maybe one day I could help my dad with some measurements of his!!!
