I used these in several ways. First of all, I would call out a number such as 1,943 and the children had to lay that number out on their desk. (They used an elbow macaroni noodle for the comma.) Another activity I did with these.....I wrote a number in expanded form on my overhead and they had to form the standard form with their cards. (I would write something like 20,000 + 1,000 + 700 + 40 + 6 and they would take their cards and place them as 21,746.) Later, I would write numbers in words on my overhead and the children would lay them out. The cards were also great for playing the Mystery Number game. I would give clues such as: I am thinking of a three digit number: The digit in the tens column is a 3. The number in the ones column is 2 less than the digit in the tens column. The number in the hundreds column is 6 more than the digit in the tens column. What is my number? (931) Now, we use them for multiplication practice. I will say something like show me the product for 6 x 7. It's just another way to practice without pencil and paper. Hope these ideas are helpful. JKB
