MY APPROACH TO TEACHING and to the offered UNITS on this website is to pepper the worksheets (and, optionally, the quizzes) with informational guides that serve as text-book-like how-to instructions. How the teacher puts it all together is left to that teacher's unique approach to teaching. In other words, these offerings are PROBLEM-BASED and not lesson-plan based. The difference is profound. I do not pretend to know how you should speak to your students and refuse to offer canned lesson plans--the material will serve as your own guide as well as for the students themselves.
ISOMETRIC drawings (plus OUTLINE or SHADOW types) have helped my students visualize objects greatly. Included here are just a few of the hundreds of problems in a few grades that require these drawings.
This unit concerns making use of the METRIC measurement system in concert with ISOMETRIC and the OUTLINE or SHADOW technique sketches.
SEVEN skill areas are included.
FOUR worksheets are provided: one with 15 problems per skill; one with 12 per skill; one with 9 per skill and one with 6 problems per skill. You decide which is best for you.
SEVEN quizzes (all with 5 problems each) are provided: TWO at a level 2 (not too hard); TWO at a level 3 (harder); TWO that are a mix of level 2 and 3 problems (I personally use these a lot) and ONE that has both level 3 and level 4 problems (the most difficult).
Answer keys are provided (as I usually do) but all grading or assessing is very subjective when it comes to sketches.
[The problems in All WORKSHEETS and PREVIEWS are printed in difficulty (1 [easy], 2 [not so easy], 3 [proficiency] up to 4 [mastery]) order within a skill. The actual difficulty level appears slightly to the left of the DK box of each problem in a very small font. Also, instructional references appear on worksheets but are optional on quizzes.]
PDF's of SKETCHES in 3 of the 7 skill areas are included as a helpful guide.

Also, look at the other MISCELLANEOUS (and IMPORTANT!!) UNITS (that are, as of this writing, not part of definite sequences like UNIT 1, UNIT 2, etc):
UNIT: ISOMETRIC Drawing (American ruler)
and UNIT: PERSPECTIVE Drawing
I can’t stress too strongly that all of these units have been designed and tinkered with from extensive experience with older students who had absolutely no understanding of these various concepts at all.
