Skills practiced

Two classic 100th day prompts invite your child to imagine: what would you do with 100 of something, and what will you be like at 100 years old? Your child draws a picture first and then writes to finish each sentence on primary lines. Kindergartners are learning to put their ideas into words, spell simple words the way they sound, and start sentences with a capital letter. Drawing before writing helps young children plan what to say, and the silly prompts make even reluctant writers want to try.

Common Core L.K.2.d: Spelling simple words the way they sound

Common Core L.K.2.a: Starting each sentence and the word I with a capital

Short descriptions in our own words. About our standards.

How to use it, step by step

  1. Your child reads the instruction out loud and explains in their own words what to do.
  2. Work through the tasks in order: the first ones are easier and warm up for the next.
  3. The task with a star is optional, for early finishers.
  4. Check together with the answer key and redo only what was wrong.

Tips for parents and teachers

Talk about the prompt first and let your child say the whole sentence out loud before writing. Then help them stretch each word slowly and write the sounds they hear. Resist correcting the spelling; invented spelling is how kindergartners learn to connect sounds and letters. One gentle check is enough: does the sentence start with a capital letter and end with a period?

Make it easier or harder

Easier: Let your child draw first and dictate the sentence to you, then copy just one or two words onto the lines.

Harder: Ask your child to write two sentences for each prompt and use a describing word, such as 100 shiny balloons or a funny hat.

Answers will vary. There is no single right answer on this page.

What to look for: a capital letter at the start, spaces between words, and a period at the end. Spelling words the way they sound, like evre dae for every day, is normal and expected in kindergarten.

Ideas if your child is stuck: If I had 100 balloons, I would fly away. If I had 100 cookies, I would share them with my class. When I am 100 years old, I will have a long white beard. When I am 100, I will tell stories to my great-grandchildren.
