This is a place value counter I've made to help my Grade 4 students understand adding and subtracting by 1, 10, 100, 1000, and 10000. It also helps to understand regrouping when adding or subtracting 1, 10, 100, 1000, or 10000. Click the "Add' buttons to increase that place value by one digit. Click the "Subtract" buttons to decrease the place value by one digit. Use the Auto-Counter button to count up by ones automatically. Enjoy!
