It's Probably Penny
By: Loreen Leedy
It's Probably Penny is a great story to read to students when teaching math, specifically probability. This book is a higher level book, such as second or third grade level. This story is about a teacher using different color jelly beans to have the students predict which color he will choose and the likelihood, or probability of that option. He explains to the students that the purpose of doing this was so they would know what to expect when they do their math homework (and it was fun). Afterwards, a student goes home and predicts outcomes about her dog Penny.
Students may like this story because they may like dogs. This story shows a young girl using probability to show that her dog, Penny, ate her sandwich, making a crazy noise, finding a buried treasure, etc. She predicts that it's... "Probably Penny!" This is something that many students can relate to back home and share the probability of their animal eating their homework.
This story could be used to create a math assignment too. For example, in the story the students math homework was to use the jellybeans and tell the likelihood of: 1.) WILL, MIGHT, CAN'T (probability of happening); 2.) Tiny chance/Impossible; 3.) Equal chances; 4.) Unequal chances. This is a way to show if students are understanding probability in a fun way.
