I designed this set specifically for use with dry erase markers. To practice our skills with place value to the millions place, these sheets will be laminated and students will use them to read, write, and decompose numbers. There are two levels included in this pack, one that has decimal places, and one without decimals. These have proven to be very useful in the classroom. All that is needed is that you print them (better on cardstock for durability) and laminate!
