You'll learn how today. Do several examples while saying the steps out loud. Point to three steps on board. Have one student explain how to measure the first length as I follow the directions on the overhead. Have other students watch for accuracy and prepare for giving feedback.
Answers are to be written in the box next to each line.
Students do first four lines individually. I monitor and provide feedback. Then, steps are quickly reviewed, one more time. There is no help from anyone. Examples of lengths to the inch and balf inch will be mixed.
