How to Use This Pack

Five pages for the 100th day of school, each showing 100 a different way. On page 1 ten full ten frames hold ten of a different picture each; students count by tens and write the total under each frame, 10, 20, 30 and on to 100 (the first is done). Page 2 is a 100 chart with the tens column and two rows left blank to fill in. Page 3 is a 100 snack mix: each row has more than ten of one snack, and students circle ten of each, then write how many snacks are in the mix. Page 4 has bundles of 10 craft sticks to count by tens. On page 5 students draw 10 dots in each of ten boxes and write the running total under each box.

In the Classroom

Use the pages on the 100th day itself, or across the week before it. Count by tens out loud as a class, pointing to each frame, bundle or box. Make the snack mix for real: ten bowls of ten pieces poured into one big bowl. Bundle 100 craft sticks with rubber bands and leave them out to count again. The 100 chart works well with a class chart on the wall to check against.

At Home

Hunt for 100 at home: 100 pennies, 100 pieces of pasta or 100 steps. Make ten piles of ten, count them by tens together, then count them all by ones and see that it comes to 100 both ways.

Tips for Success

  • Each ten frame, bundle and box holds 10
  • Count by tens: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100
  • On the 100 chart, the numbers down the right side go up by ten
  • Circle the first 10 snacks in each row, counting as you go
  • Ten groups of ten make 100

Common Core Standards Alignment

This pack supports the following Common Core State Standards for Mathematics:

  • K.CC.A.1 Say the numbers in order up to 100, counting by 1s and also by 10s.
  • K.CC.A.2 Keep counting upward from a number other than 1, within the numbers already known.
  • K.CC.B.5 Tell how many: up to 20 objects in a line, array or circle, or 10 scattered. Also count out a requested number up to 20.
  • 1.OA.C.5 Connect counting with adding and subtracting, such as adding 4 by counting on four more.
