Our class is beginning to review for the Milestone test. The math portion of the test will be on May 1st and 2nd. Any of my previous posts with videos or activities will be helpful to review. Here are some additional resources (click the hyperlink to go the resources):
Georgia Milestone Study Guide – The math portion starts on page 84, and the guide includes a review of the type of questions, studying and test-taking tips, and practice questions with answers.
Seventh Grade Math Formula Sheet
Georgia Milestone Practice Site – Practice answering middle school questions on the computer here. The questions could be from 6th or 8th grade also. This will help you become familiar with the way the test will look and work on the computer. DIRECTIONS: When you get to the web page, click the words “Online Tools Training” under the green box labeled End of Grade (EOG) – Spring Main. Select EOG Test Practice and the Standard Online Tools and Grades 6-8 (or Audio, Masking, Color Contrast, and Color Chooser if your student has read-to accommodations). Next, put in the user name and password as given on the screen. The questions at the 7th grade math level include #10-14, 16, 18-21. Questions 15, 17, 22, and 23 include 8th grade concepts. Questions 1-9 are ELA questions and 24-32 are science and social studies questions. Seventh grade students only take the ELA and math Milestone, so they do not need to practice the science or social studies questions this year. Please let me know if you have any questions. We will practice this some in class.
This week we will learn to find the volume of a rectangular prism and a triangular prism. The Unit 4 B test is on Friday. The test will cover angle pairs (complementary, supplementary and vertical angles), composite area, surface area and volume.
Visualize the volume and surface area of a rectangular prism (activity).
Video: Visualize the volume of a triangular prism.

This week we will use area formulas that we have already learned and apply them to finding the area of figures that are created from more than one shape. These types of figures are called
composite figures. Video Examples of composite figures.
These are the activities we will use in class:
Interactive Activity Explore It: Exploring Composite Figures
Interactive Activity Use It: Exploring Composite Figures
We will also learn to find the surface area of 3-dimensional figures. (Also see “What is area” if you need to review area. )
Videos: Surface area of a box
Surface area of a triangular prism
Practice: Practice surface area
This week we are reviewing angle terms and learning about important angle pairs. This week’s mathgames.com assignment is Geometry: Angles Review.
Acute Angles – measure between 0 and 90 degrees
Right Angles – measure exactly 90 degrees
Obtuse Angles – measure between 90 and 180 degrees
Reflex Angles – measure between 180 and 360 degrees
Straight Angles – measure exactly 180 degrees and forms a straight line
Adjacent Angles – Two angles that are next to each other and share a common side.
Complementary Angles – Any two angles that add up to 90 degrees.
Supplementary Angles – Any two angles that add up to 180 degrees.
Vertical Angles – Two angles that are across from each other on intersecting lines. The measure or each vertical angle is the same.
Linear Pair – Two angles that form a straight line.

This week we are learning about circles:
Vocabulary Video (1st 40 seconds only!): center, radius, diameter, circumference, area
d(diameter) = 2 times r (radius)
C (circumference) = 3.14 (pi) times d (diameter) OR
A (Area of a Circle) = 3.14 times radius times radius OR
A = (3.14) r2
Circle Videos: Circumference Area

Geometry: Circles 1 , Geometry: Circles 2, Geometry: Circles 3
This week we are learning to recognize the two dimensional shapes that are created when we slice through three dimensional geometric figures.

IXL Review Activity
This week we are discovering and using properties of triangles. Here are links to activities we are using in class:
Monday: The three interior angles of a triangle ALWAYS add up to 180 degrees.
GeoGebra Site – Polygons
Tuesday: The sum of the two shorter sides of a triangle is always more than the length of the longest side.
GeoGebra Site – Triangle Inequality Exploration
Review Concepts: The area of a triangle is always half the area of the rectangle with the same base and height.
The area of a rectangle is base times height.

Welcome back from winter break! This week we will be using proportions to solve problems involving scale drawings. Here are some of the vocabulary words we will use:
Scale Drawing: A drawing that is proportional to real life. For example, a drawing of a house would have the exact same shape as the real house, but it would be smaller.
Scale: The ratio of the length of a drawing to the length in real life. For example, on the drawing of the house, one inch might represent 2 feet on the real house. Often the scale would be written 1 in: 2 ft.
Also, on a map a scale could be 2 inches: 50 miles. This means that every two inches on the map represents 50 miles in real life.
Scale Factor: The ration of the length of the drawing to the length in real life when both of the measurement have the same units. For example, if the scale is 1 in:2 ft, the scale factor would be 1:24 because 2 feet equals 24 inches.
Here are some resources that we will use in class:
