This I Have, Who Has? game includes 20 cards, each with a two-digit number between 10 and 99. On each card, the "I have" statement is listed in standard form. Each "Who has?" question is asked with the amount of tens and ones rather than the standard form to reinforce place value knowledge of tens and ones.
On each card is a visual representation of the two-digit number using place-value blocks. Laminate these cards and allow students to play over and over again!
