I used this for a variety of things. I used it in my math centers/partner games where the students pulled a 2 digit number. After that they place the amount of tens and ones in that number by laying down place value blocks in the appropriate box. I also used this whole group by placing this in a plastic cover sheet and giving the student dry erase markers. I called out/showed a 2 digit number and they drew the tens and ones blocks and wrote the numeral! They would erase when done and be ready to go for the next number!
