Skills practiced
The 100th day of school is the perfect excuse to count all the way to 100. On this page your child counts by 10s to fill in a number sequence, sees what 100 looks like as ten full ten frames, counts by 1s across two stretches of numbers, including the tricky move from 99 to 100, and solves a quick riddle about 100 fingers. Counting to 100 by ones and by tens is a core kindergarten goal, and seeing 100 as ten groups of ten lays the groundwork for place value in first grade.
Common Core K.CC.A.1: Reciting numbers aloud to 100, plus skip counting in steps of ten
Common Core K.CC.A.2: Picking up the count from any number instead of starting at one
Your child reads the instruction out loud and explains in their own words what to do.
Work through the tasks in order: the first ones are easier and warm up for the next.
The task with a star is optional, for early finishers.
Check together with the answer key and redo only what was wrong.
Tips for parents and teachers
Count the ten frames together out loud and touch each one: 10, 20, 30. Children who count every single dot usually lose track, which is exactly why counting by tens is faster. In the 1s rows, watch the jump from 49 to 50 and from 99 to 100; these decade changes are where most children stall. A printed hundred chart on the table is a helpful reference, not cheating.
Make it easier or harder
Easier: Count by 10s with real objects first, such as ten cups with ten small items in each, and let your child use a hundred chart for part 3.
Harder: Ask your child to count backward by 10s from 100 to 0, or to collect 100 small things at home in groups of ten.
