Ending Factory

1st–2nd grade
Ages 6–8
Free, no sign-up

Jump + ing = jumping. In Ending Factory, a word and an ending go into the machine, and your child picks the word that comes out. Levels start with words that just add the ending, then -es words like wishes, then words that drop the e (baking) or double the last letter (hopping).

How to play

Look at the word and the ending. Like jump + ing.
Think about the rule. Just add, drop the e or double?
Pick the right word. The factory explains the rule.
Finish the level. Three stars for first-try answers.

For parents: what Ending Factory practices

Ending Factory teaches inflectional endings, which helps kids both read and spell longer words. It pairs with:

Common Core: RF.1.3f (read words with inflectional endings), L.1.4c (identify frequently occurring root words and their inflectional forms), RF.2.3.

Getting the most out of it

Cover the ending with a finger to find the base word.
Silent e drops before -ed and -ing.
Hop, stop, run: short words double their last letter.

Games are best as a reward or a warm-up, not the main lesson. Ten minutes of play after a short lesson works better than an hour of play on its own.
