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.
This is a fairly comprehensive treatment of both measuring systems. I have used most of the 10 skills and hundreds of problems in my various courses at the secondary level. I find that most students are woefully ignorant of measuring systems but are quite grateful after covering them in detail.
Included are 4 worksheets--with 6, 10, 15 and 20 problems per skill (of which there are 10) to accommodate most any user. Additionally, 7 quizzes are also included that have varying difficulty levels.
All of the foregoing have answer keys included as well.
THE IDEA BEHIND THE ASSESSMENTS IS THAT IF YOUR STUDENTS CANNOT PASS ANY OF THEM THEN, MAYBE, THEY COULD BENEFIT FROM THIS ENTIRE UNIT.
Look at the PREVIEW. It should give you a good feel for the entire unit.
[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.]
You might also want to check out other 4th grade offerings here. The 4th Grade Summary
will link to a variety of other items such as the logical sequence of units on FRACTIONS and DECIMALS beginning with UNIT 1: SIMPLIFYING, REDUCING fractions
and the MISCELLANEOUS (and IMPORTANT!!) UNITS (that are, as of this writing, not part of definite sequences like UNIT 1, UNIT 2, etc):
UNIT: COMPOSITES and PRIMES
, UNIT: DIVISIBILITY
and, finally, UNIT: FACTORS and MULTIPLES
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.
