Place Value Freebie! These arrow cards support place value skills and concepts and can be used to teach place value from ones to the millions. Aligned with Common Core Standards. Students can organize cards horizontally or vertically to represent numbers in expanded notation. They can be color-coded when printed so each place value is a different color. Students in the lower grades can work with arrow cards up to the hundreds or thousands while students in the upper elementary grades may benefit from using the cards up to the millions.
