This is a quick station or small group activity. The students will choose a s'more number card (numbers 10-30) and then choose the three corresponding cards that go with it.
12 would be a 1 card, a 2 card, and the card showing 12 in base ten blocks.
Two sets are included: one has "tens" and "ones" labels and the other does not. Otherwise they are identical. Choose the set that is best for your class.
Please note that a recording sheet is not included with this activity. My students love to use an old smartphone to take pictures when they complete their work if there is no recording sheet. I try to avoid the copy machine as much as possible!
