**Warm-Up Activity: Skip-Counting Chains**

Teacher reminds students of skip counting, and the class skip counts a few sequences of numbers orally. Students are seated four to a table. Teacher puts strips of construction paper with different numbers on them on each table. These strips of paper will form links in chains. The strips of paper should be in a variety of colors, seasonally appropriate if possible, so that the chains can be attractive garlands to decorate the classroom. Each table is to make two chains of numbers. One table may be instructed to make a multiples of 2 chain and a multiples of 6 chain, and they will have all the links they need, plus some they don’t need. Students choose the links they need and the order in which they need to arrange them and then tape or glue each strip of paper end to end with itself, interlocking with the next link, to make a chain. Students hang up the chains around the room.

**Main Activity:**

Students should watch instructional video for Crossing Math Canyon before playing on classroom computers
