# 100th Day of School Collections

Share/Bookmark

100 items–children predict weights, weigh, and chart results.

Materials:

• Bags of items of 100
• something to weigh your items
• I prepare bags of 100 pennies, 100 popsicle sticks, 100 pasta noodles, 100 fruit loops and any other 100 items I can find.

Lesson Plan:

• I read the book Benny’s Pennies   (There is probably a better book out there for this, but I have not had time to look.)

• We guess which bag of 100 items weighs the most down to the least.
• We then test our guesses and chart them. Sometimes we are amazed at the results.
• After charting our guesses and the results we hang the chart out in front of our room along with the bags of items weighed for the rest of the school to see.

### More 100th Day of School Collections

I have the children bring in their own collections of 100 items.

Lesson Plan:

• Collect empty plastic peanut butter jars to use each year.
• Read 100th Day Worries by Margery Cuyler – It is about a girl who has to bring in a collection of 100 items. It’s not exactly what we do, but it helps the children get some ideas, and know what NOT to do.

• Place a label on the jar with the child’s name (masking tape works fine).  Send a parent letter with the jar, which explains the 100th day of school, activities you have planned, and how filling the jar with a 100 collection will be important for their child’s learning.
• Give suggestions: toothpicks, coins, beads, macaroni, paper clips… anything small enough to fit in the jar. All 100 items must be the same thing. (For instance, don’t send 40 paper clips, 20 toothpicks, 20 beads, and 20 marshmallows.)
• Instruct them to help their child count by ones to make 10 piles of 10 items. Then, they should count by tens to put them in the jar.
• Let them know what day they need to have their collections returned. I sent them home on a Wednesday, and asked to have them by Monday. (The 100th day was Wednesday of that week.) I had most collections returned by Friday!
• We weigh & chart the items as explained in the related lesson below (100th Day of School Collections).
