We worked on cumulative review questions on simplifying algebraic expressions. Then we practiced finding the surface area of a house. Next, we completed word problems.

Topic 8-4 Find Volume of Spheres – We learned that the volumes of the sphere and cone are proportionally related. The volume of a sphere is twice the volume of a cone that has the same circular base and height. The formula for the volume of a sphere is V = (4/3) pi r3 where r is the radius of the sphere.

We practiced finding the volume and surface area of composite figures.

We reviewed for the seventh grade final exam in mathematics.

Jonathan practiced memorizing formulas for his final exam. We reviewed the equation of a line, slope, parallel, and perpendicular lines. Then we looked at Khan Academy entries to redo as many as possible.

Test on Topic 8 Solve Problems Involving Geometry.

I planned for math.

8-9 Solve Problems Involving Volume – We reviewed finding the volume of various three-dimensional figures. Then we solved problems from the Review concepts and skills for Topic 8 Solve Problems Involving Geometry.

8-9 Solve Problems Involving Volume – We calculated the volume of various three-dimensional figures. Then we solved problems involving the volume of three-dimensional figures. To find the volume of a prism, we discovered that we had to find the area of the base (B) and multiply it by its height.
