Volume 4 is what makes us different... This book teaches basic geometry concepts that are typically taught throughout elementary school.  This is a different order than what Common Core teaches.  We feel that it is too much to ask of a young student to go from long division to fractions to using pi to find the circumference of a circle.  We prefer to teach prealgebra before asking a student to use formulas such as C = d x pi.  This book shouldn't be skipped unless your student can name the three special triangles, and what's so special about each one, and understands how to use the Pythagorean theorem.  If your student can solve for the length of the hypotenuse in a triangle with sides measuring 6 and 8, then you may skip this book.  After reading this volume, a student will quickly know the answer is 10.‹OPTIONS:Our Geometry Kit is sold separately.  It is not required, but it is helpful especially for visual learners.  This kit gives students hands-on tools to help them learn and remember the geometric concepts taught in this book.  The items included in the zipper pouch are:

A 12" x 12" piece of paper to visually see a one square foot.
Two cards that show WHY we use pi to solve for circumference
A pencil
A protractor
A bouncy ball to demonstrate a sphere vs. a circle
Fifteen 1" x 1" foam squares are used to cover a 3" x 5" card.
An Isosceles Triangle with triangle facts printed on it
A Right Triangle with its own facts printed on it
An Equilateral Triangle with equal angles printed on it
A card that proves a triangle is half of some square or rectangle
A small card that lists the most frequently used geometry formulas
A 3D cube cut-out with cube facts printed on it

‹Stand Alone or Supplemental?  Volume 4 covers basic geometry, which typically isn't singled out as a class in public school.  It is usually integrated during basic math.  If your goal is to learn geometry, this is a perfect precursor to volume 7, our high school geometry book. If you want to prepare your student for algebra, then read volumes 1 - 4 as a stand- alone curriculum.‹Scope and Sequence (Basic Geometry):Students will gain knowledge in basic geometric concepts including the difference between straight, parallel and perpendicular lines.How to identify obtuse, acute, opposite and right angles.The properties of right, equilateral and isosceles triangles are studied.The difference between several quadrilaterals and the properties they contain.Students will learn how to find the area of a triangle, a square and all other polygons.Pi, radius and diameter are used to find the circumference and area of a circle.The Pythagorean Theorem is studied and proven to work.Perimeter of a shape, and volume of a rectangular prism and sphere are learned.Students will gain knowledge of the Metric System.
