Math Resources for the 100th Day of School

100harris.jpg100 Days of School by Trudy Harris
 This delightful variation of a counting book could easily be adapted for use with students from kindergarten through fifth grade. Number combinations for 100 are explored through a collection of riddles children can relate to – “If you eat 10 salty peanuts every minute for 10 minutes, what do you get? 100 peanuts. And … (big mistake) a tummy ache!” The colorful illustrations support the rhyming text.

100th Day Worries by Margery Cuyler100worries.jpg
 Jessica's first-grade teacher asks each student to bring in a collection of 100 things as part of their celebration of the 100th day of school. What to bring? “100 ice cubes? Too melty. 100 marshmallows? Too sticky.” Jessica frets and worries, then with some help from her family, she finally ends up with 10 groups of 10 items each to take to school on Day 100.

0n the first day of school, Jessica drops one penny into a jar. The next day Plink! Evan adds his penny to the jar. When the kids in Mrs. Madoff's class count 10 pennies, they know they've been in school for 10 days. This K-2 counting book offers some nice connections with models familiar to students such as the kindergarden clip collection and the first grade “Totally Ten” from Every Day Counts. Several pages provide opportunities for children to count items by tens, leading up to the 100th day when the class has 100 pennies to count (pictured in the book as ten rows of 10 pennies).

Emily's First 100 Days of School by Rosemary Wellsemily100.jpg
This author has given us another winner in a creative book that can be used to celebrate the beginning of a new school year as well as the 100th day. In a collection of 100 brief vignettes, Wells demonstrates the use of numbers in every day life. On day 75, “Grandpa is building a clipper ship out of matchsticks. He keeps a seventy-five-watt bulb in his work light.” While there are some opportunities to use the short stories as springboards for further number exploration, the book is most suited for use in the primary grades.
