You did not mention the stage of the beets and lettuce. A hard freeze can turn the foliage to mush. If your beets have formed storage roots and the lettuce has formed a root system, you should harvest them. Most leaf lettuces can be harvested when 5-6 inches tall. Otherwise, provide some frost/winter protection and you will have to take your chances. You can cover the plants with a floating row cover which is a spun bonded fabric that provides some frost and insect protection. Row cover comes in many widths, sizes, and weights. Heavy-weight FRCs are usually used to extend the growing season in spring and fall, allow 50%-70% light transmittance, and 4º-10ºF. of frost protection. http://extension.umd.edu/sites/default/files/_images/programs/hgic/Publications/not_updated/GE004Flo...
If you do not have a row cover you can cover with a heavy plastic but remove during the day for good air circulation. Strong sunlight can cook the plants.

I bought seeds…the package said they were winter vegetables…plant in Sept-Oct in Maryland, so i am very confused. the beets leaves are very small-not like what i see in the groc store! Maybe 3-6 inches…don’t see how they could have any beets yet…one lettuce looks ok, about 6-7 Inches, the others are tiny as the beets-most lettuce did not come up. So why plant seeds as a winter crop. if the freeze will kill them…i am so confused.

September-October is really too late to plant beets in Maryland. Leaf lettuce should be in the ground by the beginning of September.

Winter crops do not so much grow during the winter, as they can survive with protection if they are well established already.

Here is a good chart, specifically for Maryland, to help schedule planting: http://extension.umd.edu/sites/default/files/_images/programs/hgic/Publications/HG16%20Planting%20Da...

Winter crops (beets, spinach, tough lettuce such as endive, escarole, arugula) generally need to be in a tunnel of heavy row cover, or a cold frame, or very heavily mulched.
