Lesson Objectives. The student will be able to:
1
2
3
Mark lumber for correct measurements prior to cutting
Measure correct length and width for cutting
Read and reduce fractions to 16th,s to mark and measure correct dimensions as assigned
Tools and Equipment
Tape measure
steel rulers
wood rulers
try square
6”by6” by ¼ “ wood stock
#2 pencils or carpenters pencils
Key Terms / Vocabulary
reducing fractions down to 16th’s
try square
tape measure
wood stock
width
length
edge
Interest Approach/Anticipatory Set
Students will be constructing simple lab projects to specific measurements per various sketches and
drawing in AFNR lab. It is important to know how to properly mark and measure dimensions per
blueprints and assigned measurements. Accuracy is critical in doing a job right and to reduce waste
Teaching Plan and Strategy / Presentation of New Material
1 Students will be given a platform stock piece
2 Students will use one side of stock to measure the width of 10 assigned measurements using
tape measures, try squares, and steel rulers and drawing a line the designated width.
3 Students will use the other side of wood stock to measure the assigned length (height) of ten
assigned measurements
4 Students will mark and measure lines; remember to reduce all fractions to lowest common
denominator.
Activity/Application/ Student Engagement /Laboratory
Students will receive a lab sheet with designated width and length inches and fractions to measure.
Students will do their own work with reinforcement/ re-teaching provided by the instructor. Upon
completion of the 20 assigned measurements, students will label and turn in their stock for a grade.
Evaluation / Summary
Instructor will apply a tape measure and one other device to determine the accuracy of each
measurement
