This is a very fun 30-card "I Have - Who Has" review game for upper elementary. The questions are primarily "in the thousands" - with one challenging "in the millions" card included. This game includes a review of place value, comparing numbers, and expanded/standard form.
I have included the directions for playing "I Have - Who Has" just in case you are unfamiliar with this game.
