Math Mammoth Geometry 2 continues the study of geometry after Math Mammoth Geometry 1, and is suitable for grades 6-7. It concentrates on two broad and important topics: area and volume of all common shapes.
In the first section of the book, which is also the longest, students learn to calculate the area of all common shapes: triangles, parallelograms, other polygons, and circles. They also learn about Pi and the circumference of a circle.
Next, we study nets and surface area of common solids. Naturally the student needs to know how to calculate the area of two-dimensional shapes by this point (specifically, the area of rectangles, triangles, and circle). There is one more section about area, in which we learn how to convert between various units of area, both metric and customary.
Lastly, the book teaches about volume of common solids. I assume the students already know how to find the volume of a right rectangular prism (a box). First we expand this topic by calculating volumes of rectangular prisms with fractional edge lengths. Then we go on to calculate volumes of other solids: prisms, cylinders, pyramids, and cones.
Besides simple calculation exercises, the lessons contain many real-life applications, word problems, and mathematical problems concerning area and volume. I have tried to create a variety of problems to encourage students' problem-solving skills.
These topics (area and volume) involve lots of calculations, and the calculator is allowed in the problems that are marked with a little calculator image.
The earlier version of this book (before March 2014 or before Edition 3) covered a different list of geometry topics.
