Letâs compare numbers! Join Ms. Lassiter for this lesson that encourages students to find 10 more, 10 less, 1 more, and 1 less than a number and use symbols to compare numerals to 100. Students will need a whiteboard and marker or pencil and paper. If you have access to a printer, we suggest printing the Place Value Chart template, Comparison Cards template, and Problem Set using the links below the video.
