This is the first worksheet in the Brain Teasers series. The Brain Teasers series of worksheets is a compilation of Mensa and SAT-style math problems and puzzles. These worksheets provide enrichment in basic Arithmetic, Plane Geometry and Algebra 1 concepts, coinciding with Common Core standards at grade 6 and above and requiring no more than a thorough understanding of that material. Each worksheet includes definitions of terms and formulas that are relevant to the problems on the specific sheet. There are four levels of sheets - Somewhat Easy (SE), Medium Difficulty (MD), Somewhat Difficult (SD) and Dare You! (DY), loosely graduated by difficulty on each worksheet.
