This is a variation of The Teacher Wife's Even & Odd Street. I saw almost the exact same thing on another blog, but I don't remember where. If this is your idea, please let me know, so I can give you proper credit.
The students chose three playing cards from a deck and arranged them in ascending order. They wrote their number combinations onto slips of paper and we practiced sorting them into even and odd. Students lined up in ascending order and descending order, based on the numbers they chose. This was also our first experience with expanded notation, which I demonstrated using 1s, 10s, and 100s manipulatives.
Finally, students collected the appropriate number of pre-cut construction paper 1s, 10s, and 100s in order to represent their number visually. I love the way they turned out! I have a creative bunch this year!
