Cover page of 100th Day of School Math

The 100th day of school is a milestone worth a whole day of math. This pack gives you pages for every part of it: children make 100 with tens and ones, find ten pairs of numbers that make 100, fill in missing numbers in pieces of the 100 chart, skip count by 2s, 5s and 10s, estimate and then count a collection of 100 things, tally and graph what a class can do in 100 seconds, and write the number words for 100.

Every page is pure number work and needs nothing from outside the classroom, so it fits any class on any day, whether you reach the 100th day in January, February or March. Teacher notes give a half-day plan, the materials list and ways to make each page easier or harder for children in Kindergarten, Grade 1 and Grade 2.

Inside: teacher notes, ten children’s pages (including a dice game and a check-up) and a worked answer key. Print in black and white on any printer. The free sample is the teacher notes and the Ten Ways to Make 100 page.
