A collection of 26 8th grade topics (out of 171 as of 6/25/2015) that a true STEM enthusiast should be interested in and try to master. The 4 sets of problems have 208, 156, 104 and 52 problems respectively--with the answer keys provided as well.
STEM careers require enthusiasm and ultimate mastery of a variety of topics in mathematics and there is quite a bunch of them here!
On this website I offer CHALLENGING, WORD and STEM problems by grade. Although there is natural crossover between the 3 types of problems, I try not to have any of them belong to more than one category but several of the topics included here could be valuable CHALLENGING topics as well. With over 42,000 problems (and growing) in my database it is only logical to conclude that there would be a sufficient number to properly populate all three categories!
The PREVIEW is comprised of 1 problem in each of the 26 skills that have been chosen for the 4 sets of worksheets. Take a look--it is a good measure of the entire package and most of these problems you have never seen the likes of before.
[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.]
