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 should be an initial pair of lessons on primes and composites as it focuses, first, on numbers from 2-50 and, second, on numbers from 51-100.
FOUR worksheets are provided: one with 20 problems per skill; one with 15 per skill; one with 10 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 for all worksheets and quizzes.
[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 offerings 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: FACTORS and MULTIPLES
and, finally, UNIT: MEASURING (American and Metric)
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.
