What is a number.? Is 23 just a 2 and a 3? That’s what we have been looking at, what makes a number through place value chart of tens and ones. We had counted up beans and our 100 snacks with tens and ones. This week we counted our pockets. Here’s the rule: 1 pocket = 1 cube. Each student puts a cube into each pocket. Then put all their cubes in one row (or none). Add up their row with each table group member’s row of cubes. Each team would have a row of cubes representing their group. Then we come to the floor and we place it in our 10s and 1s place value chart. If we have a row of cubes, we count it up so that if it reached 10, we say, “cup it, bundle it, make it into 10.” Then we place the row of 10 into the 10s place.
Look at a day’s counting of 10s and 1s. At the end of it we total it up. All the while, we are coordinating what we see with the hands-on cubes to writing it into 10s and 1s. What is our final 3-day total???
