This math activity is to assist with 1:1 when counting to 11-30. Simply print on cardstock. Then cut around the perimeter of the rectangle. When you cut around the rectangle the number will be displayed on both sides. On the blank side adhere a string ( 8 inches long) or a pipe cleaner. Then glue together making sure to fold along the middle line. Have your class count and add beads to the string to form the number displayed. Hope you enjoy!
