Arrow cards are a great tool to help students to develop an understanding of place value. This particular set brings students to the ten thousands place so they can be used with older students. Along with building and extending upon place value concepts, using this tool allows students to understand writing numbers in expanded and standard form. There are two sets of arrow cards included. One is in color and the other is white. The white arrow cards allow you to print onto colored paper or tag board of your choice. Laminating is highly recommended.
