Multi-touch issues on Chromebooks and Lenovo Yogas can be complex due to the touch interaction pieces and cross-browser compatibility. We recommend that users with multi-touch devices use the cursor while completing assessments. Using the touch functionality, or switching back and forth between cursor and touch, can cause errors in graphing, number-line plotting, or drag-and-drop answers. Below is a list of known issues with the Big Ideas Math Dynamic Assessment System and these types of devices. These issues are not with the Big Ideas Math website as a whole.
