This parking lot game is a play off of an old game from the beginning of the year from Heidi Song. The students each have a bag of a certain color domino and they pick out a "car" and place it in the correct parking lot. So a domino with 3+4 dots, would be placed in the Parking lot 7. I printed an extra 1 and 2 to make the 11 and 12.
this set of cards.
This has been a great introduction to the ten cubes. I have had the students play as a team and take turns so they can check each other and help to make a set of ten. I will not do this one for very long, but I do like having the students work with these and at least be familiar with this.
