Acknowledging the 100th day is a great way for elementary school teachers to celebrate math concepts that can be taughtusing the number 100. Asking students to collect and bring in items to be used for these lessons also encourages class participation.
Developmental Math Concepts
From the very first day, many classes begin keeping track of the number of days they’ve been in school in anticipation of the 100th day. It’s this anticipation that is actually the first math lesson.The days are often marked using objects like coffee stirrers or Popsicle sticks. Ten of these sticks become a “10 bundle” that will pave the way to counting by tens and ones.Any 100th-day math activities should be appropriate for the developmental stage of the children in the class. Preschoolers and kindergartners generally don’t count past 20, so collections of 100 should focus on bundles or groups of five or 10.In first grade, children can count to 100. Doing a count-up or count-down is appropriate. By second grade, they can usually count to 100 by twos, fives, or tens, so items can be bundled in different number groupings.By third grade, kids can often do multiplication and division. But for numbers as large as 100, more complex math problems may not be appropriate until fourth grade.
Class Collections for the 100th Day of School
If the class is planning a 100 Day celebration, your child may be asked to bring in some items to add to the class collection. It’s not always practical for each child to bring in 100 of any item. Try to get a sense from your child’s teacher of what they have planned.Students will often be separated into groups, with each group responsible for having a collection of 100 things based on a specific theme.For instance, one group may be asked to bring in 100 things from the kitchen, which could be foods like dried beans or Cheerios, items like spoons or forks, or a variety of other things. Another group idea could be 100 coins or 100 different office supply items (such as paper clips, pens, and staples).Whichever way your child’s class decides to mark its 100th day of school, be sure you know what the teacher expects and how the items will be used.
Ideas for Individual 100th School Day Collections
Alternatively, your child may be responsible for their own collection of 100 items. They may need to bring them as a display (such as glued onto a board) or they may do a project with them in the classroom. Options include:
