The 100th Day in Kindergarten

The number 100 is a landmark number and deserves its own day.

We counted each day that we went to school with the knowledge that when we reached the number 100 we would celebrate.

Our math system was formed using base ten numeration. This means that all digits find their place on the number line using one rule. The value of a digit is 10 times the place to its right (the 3 in 63 is worth just 3 but the 3 in 36 is worth ten times as much).

In Kindergarten, the children notice the sequence of the numbers and the patterns that exist on number lines and grids to 100. As the children become familiar with the concepts of digits they begin to lay the groundwork for understanding place value in first grade.

We have discovered that:

  • The numbers in a column all end with the same number.
  • In each row, as we count left to right the right, the digit goes up by one number but the first digit (the ten) stays the same.
  • In each column. the first digit (the ten) goes up by one as we descend. 
  • We practice counting by tens as we descend the far left column on the hundreds chart.

We have also  considered the neighbors of each number on the number chart. We complete one hundred charts with numbers missing and use our knowledge to identify the missing number.

We use the hundreds chart to practice skip counting by twos and five and tens.
Our celebration began with a story.

As we planned the celebration,  a group of children expressed interest in dressing as a Super Hero 100. Our day included an opportunity to adorn our Super Hero (or princess) capes with 100 designs.

C. counts the flowers that she has carefully sketched on her cape.

T. and T. are the first to attempt to build a structure with 100 red plastic cups. It was challenging from a building perspective. The weight of the cup added to the difficulty.

L is deep in thought customizing her super hero cape.

A super Hero is spinning their web of cold ice cream with the hopes of entrapping the spider. This customized insignia is closing the gap between 0 and 100.
It took some time but the structure is tall, sturdy and erect.

Lira uses a strategy to reach 100 designs...ten circles with ten designs in each circle.

Another partnership forms with the goal of using all of the cups in a standing structure.

L. assembles a 100 piece puzzle.

This partnership is building in the round and is fueled by much debate.

In the afternoon we tested the strength of our body and our endurance.
Are we able to complete 100 exercises?

The Grand Finale! Thanks to some lovely moms we counted 100 muffins and answered the following question.

How do we divide the muffins so each child has an equal amount of muffins?

We used skip counting to discover that  each child  receives five muffins. 

Yet another structure is erected.

Super Heroes and Royalty assemble for a group shot commemorating day 100.
