How we use I Have, Who Has? to get a whole class listening
For eight minutes every child in the room is doing mental math and nobody talks out of turn, because the only way to speak is to have the answer.
Twenty-four second graders, twenty-four cards, and one rule: listen for your number. "I have 14. Who has 6 + 7?" A pause, then a voice from the back: "I have 13. Who has 9 + 9?" For eight minutes every child in the room is doing mental math and nobody talks out of turn, because the only way to speak is to have the answer.
What the sheet looks like
The I Have, Who Has? generator prints a closed loop of cards: every card reads "I have … Who has …?" and the last card's question points back to the card marked START, so the chain always ends where it began. Decks cover numbers 1–30 (as number words, ten frames, numerals or mixed), addition, subtraction, multiplication, division, place value, telling time on analog clocks (hours and halves, quarters or five minutes), coins, 2D and 3D shapes, Dolch sight words, or your own answer | clue pairs. Decks come in 12, 16, 20, 24 or 30 cards, eight to a page with dashed cut lines.
The teacher call sheet lists the cards in order so you can follow along and find the break when the chain stalls.
Why it works
- Every child has to solve every clue, not just their own, because they do not know which one is theirs until they hear it. That is 24 problems of mental math per child in one round.
- The loop is self-correcting. If nobody answers, the class knows exactly where the mistake is, and whoever holds the card works it out with 23 helpers.
- Your own pairs turns the same structure into a review for anything: a state and its capital, a word and its definition, a fraction and its decimal.
Who it suits
Kindergarten to fourth grade, with the deck size matched to the class and a few kids holding two cards if the numbers do not fit. Numbers with ten frames are a kindergarten deck; multiplication, division and five-minute clocks are third and fourth grade. It is a whole-group game and a poor fit for one child at home; the bingo cards cover the same content for a family table.
Print on card stock and keep each deck in a labeled envelope with its call sheet. A deck missing one card does not loop.
