This is a unit bundle of lessons on Trigonometric Functions most likely for an Algebra 2 or Trigonometry course. It starts out with a review of right triangle ratios of sin, cos, and tan while introducing the reciprocal function ratios. Angles of rotation and coterminal angles are introduced so that the Unit Circle can be fully developed. A blank unit circle with space for marking special angles is included so teachers can decide how they want to develop and present the unit circle and its pr

This is a Unit plan/bundle of worksheets/handouts that can be used as notes/lessons and accompanying homework sheets. Each lesson explores the properties of a solid (Prism, Cylinder, Pyramid, Cone, Sphere), works with the volume of the solid, and in some cases the lateral or surface area of the solid. Varied problems using the formulas are included. There is a cumulative review included which has a bunch of problems mixed up from the entire unit. Finally, a unit exam including multiple-choic

This a unit bundle of handouts/worksheets that can be used as lessons. This unit is most likely usable in an Algebra 1 course that studies one unit of basic probability and statistics. Students start off learning basic probabilities and then delve into compound probabilities (those involving AND and OR statements). Students then work with the counting principle and construct tree diagrams and/or list sample spaces to find the probabilities of compound events. The second half of the unit has

This lesson is a high school level geometry introduction to triangle concurrency. The first lesson focuses on the properties of the centroid, using coordinate geometry to locate the intersection of the medians. The second lesson uses an online applet to investigate the properties of the other three major points of the concurrency (the orthocenter, incenter, and circumcenter). A comparison of all concurrent points are made and practice multiple choice questions are included. A homework assign

This is a unit bundle of handouts/worksheets that can be used as lessons most likely for an Algebra 2 course or even a basic statistics course. The unit starts out with lessons on theoretical, empirical, and geometric probabilities. Students then investigate what permutations and combinations are as well as a mixed lesson on identifying which is which. Using their knowledge of combinations, students can then calculate binomial probabilities (including examples asking for exact probabilities as

This is a Unit bundle of handouts/worksheets for a High School Geometry course on Coordinate Geometry Proofs. Included are worksheets that may be used for lectures/notes, classwork/practice, and homework. Students are first introduced to the distance formula. A lesson on proving lines parallel, perpendicular, and congruent comes next. We jump right into coordinate proofs that prove quadrilaterals are parallelograms, rectangles, rhombuses, squares, and trapezoids. A lesson on proving triangl

This is a unit bundle of lessons/worksheets on Trigonometric Identities and Equations. Students begin by finding all six trig functions if they know one, which leads nicely into the first identities lesson on the Quotient and Reciprocal trig functions. Next, students work with the Pythagorean Identities, the Double Angle formulas, and the Sum and Difference of Angle formulas. All lessons contain identity simplifications and numerical examples. A mixed practice of identities and a mid-unit quiz

This is a Unit bundle of lessons/worksheets that explore the properties of the parallelogram, rectangle, rhombus, square, and trapezoid. Students list the properties of the figures and then answer questions about their properties, including numerical problems. A quadrilateral property checklist is included as well as a "Who Am I" worksheet which asks students to identify quadrilaterals based on their properties. As a study guide of the properties, a quadrilateral family tree diagram with the

A high school level Transformations unit for a geometry course. Individual lessons/worksheets define and give detailed examples of reflections, rotations, translations, and dilations. Each worksheet/lesson allows space for definitions of each type of transformation as well as examples of their use on a coordinate grid. Properties of transformations are also investigated. A summary lesson on transformations of triangles and quadrilaterals in the coordinate plane is also included. The Reflect

This is a Unit bundle of lessons/handouts on Logarithms and Logarithmic functions. Students are exposed to logarithms as they are inverses of exponential functions. After the connection between logarithms and exponents is made, students then work with the logarithmic form of an equation. Logarithm properties are introduced and students then solve logarithmic equations that employ using the properties learned. Students then solve exponential equations using logarithms and finally work with wo

This is a Unit bundle of worksheets/handouts that can be used as lessons to teach the concepts of perimeter, area, and volume or as worksheets for homework, practice, or additional problems. Students begin with an introduction to the perimeter of polygons. The areas of common geometric figures are explored (parallelogram, rectangle, square, trapezoid, triangle). Students then work with the circumference and area of circles (often finding one when they know the other). Finally, the volume and

This is a Unit for an Algebra 1 course. The Unit contains worksheets as handouts that can be used as notes plus additional practice worksheets for many of the lessons. We start by translating verbal situations into algebraic expressions, then delve into solving all types of linear equations, from basic to complex, including with decimals, fractions, distributing, variables on both sides, and combining like terms. There are also lessons applying solving equations including consecutive integer

This a Unit bundle of lessons/handouts on Conics. Students learn about the terminology used with all of the conics. Parabolas are introduced first involving the graphing of parabolas and applications of graphing parabolas (max/min problems). Students also analyze the axis of symmetry and vertex and complete problems involving these special features of a parabola. Next, students explore the similarities and differences of circles and ellipses, including graphing and writing the equations of

This activity is great to use at the end of a unit on Volume and Surface/Lateral Area of 3-dimensional solids. Students use a set of manipulatives to observe the properties of and measure and calculate the volume and area of prisms, cylinder, pyramids, cones, and spheres. Students work together in groups so they may confirm or revise their evaluations of the figures and check and confirm their calculations. The assignment can be collected and graded as a summative or informal assessment.

This is a Unit on High School level Logic. The unit is comprised of worksheets/handouts that can be used as a formal lesson or class notes or even for practice. Topics included are Mathematical vs. Non-Mathematical Sentences, Negation, Conjunctions/Disjunctions, Conditionals/Biconditionals, Inverse, Converse, and Contrapositive. Short cumulative reviews are included in most lessons. A ten-question mixed unit review is also included which could serve as a review sheet for a unit exam.

This is a unit bundle of lessons/notes in the form of handouts/worksheets on Sequences and Series. Certain lessons have additional practice/classwork sheets that can be used during class time or for homework.
