100th Day Fun

The 100th day of school opens up so many avenues for fun, and motivating math activities using a wide variety of math skills.  We begin the year counting the days until the 100th, every day we write the next number on our hundreds chart. 

 When we reach the hundredth day we have a big celebration, where each child brings in 100 things from home. For our celebration we created a tic tac toe board of a variety of exciting math centers.  After I had explained each center, we decided how many children could be at each center at a time (children are great at establishing their own 'rules' they tend to follow them much better than if they were teacher imposed).  Children circulate freely to the centers that they need to create a straight line on their tic tac toe board.

What can you Build with 100 things?

Using lego, blocks, and a variety of other math manipulatives, children counted 100 and created their own structure.

Pattern Name

On a blank hundreds grid, students write their name filling up every space, then they see what kind of pattern is made.  After comparing all the name grids we learned that names with an odd number of letters make a very interesting pattern.

Crazy 6's

This game is great fun for 2 players.  Each child gets a dice, a blank hundreds chart and a pencil.  One player begins by rolling the dice, while the other starts writing numbers in their hundreds chart.  When the player rolls a six, they take the pencil from the other player and begin writing their own numbers.  The first player who completes the entire hundreds chart wins.  Children love to play this game over and over again.

Fruit Loop Necklace

This is an old standby that all children love.  They count 100 fruit loops and string them on to a licorice string to create an edible necklace.

100 Steps

This motivating activity has the children estimating where they think 100 steps out the classroom door will get them, then they try it out and record where they really ended up.

100 things Weigh

Students weigh their 100 collection that they brought from home.  We used wooden blocks, and recorded all our weights on a chart then compared them later.

I Could ____ But I couldn't ____ Book

Using this sentence started children created one page to our 100s day book.  For example: I could eat 100 M&Ms but I couldn't eat 100 horses.

Value in a Name

I assigned a value to each letter of the alphabet, then had children use the calculator to determine their name's value. Example: KATHY = 11+1+20+8+25=65

After they determined the value we recorded them on a large chart and compared whose name was the largest and smallest value.

100 Rolls

In this probability center children roll the dice 100 times recording the rolled number on a hundreds chart.  Then they create a graph of the times the numbers 1-6 came up on the dice.

  The internet is a great place to find many 100th day activities.  Here are a few of my favourites:
