Teachers love our sturdy place value flip charts. The Versa-Flips(tm) cards are made of solid sturdy plastic that will never tear or bend. They are easy to clean and don't cost much more than a paper flip stand. The top of the chart features fasteners that allow you to remove or rearrange number cards based on the lesson of the day.
The larger teacher card set features 4" x 6.25" cards that students can easily see from their desks. You have your choice of Hundreds, Tens, and Units or Thousands, Hundreds, Tens, and Units. The student cards measure 2" x 3.12" and come in a set of five.
