Essential Skills - View all grade levels

Reading Essential Skills

  • Expand vocabulary in reading, writing, and speaking.
  • Recall and organize information.
  • Use knowledge of literary devices (allegory, figurative language, imagery, point of view, and symbolism).
  • Analyze details.
  • Analyze poet’s use of imagery and personification.
  • Give credit for information.
  • Demonstrate correct use of verb forms and tenses.
  • Demonstrate a correct use of sentence structure.
  • Demonstrate a correct use of parallel structure.
  • Spell studied words correctly.
  • Demonstrate a knowledge of literary elements.

Reading Strategies

  • Be a role model. Let your child see you reading.
  • Subscribe to the local newspaper or purchase the Sunday edition, and work the crosswords and crypt-a-quotes.
  • Make sure that your child has a library card, dictionary, and thesaurus, and encourage their use.
  • Before applying in person, ask your child to write a letter to the manager of a business inquiring about a job.
  • Give your child a confusing piece of correspondence you have received. Decipher it together.
  • Encourage your child to find the hidden catch in junk mail offers.
  • Choose a book which has been made into a movie. After both you and your child have read the book, see the movie together and talk about the similarities and differences (The Bourne Identity, A Walk to Remember, The Manchurian Candidate).
  • Visit www.collegeboard.org and sign up for the SAT’s “Question of the Day” to be e-mailed to you each day.

Geometry Essential Skills

  • Use the angle relationships formed by parallel lines cut by a transversal to solve problems.
  • Identify relationships between pairs of angles (adjacent, complementary, and vertical).
  • Use the relationships of congruency and similarity to determine unknown values (e.g., angles, side lengths, perimeter, circumference,area).
  • Use logical reasoning skills (inductive and deductive) to construct and judge the validity of arguments.
  • Find the distance between two points; the mid-point of a segment; and calculate the slopes of parallel, perpendicular, horizontal, and vertical lines.
  • Compute length, perimeter, or circumference, area, volume, and/or surface area of geometric figures in a variety of contexts.
  • Find angle measures and arc measures related to circles.
  • Find angle measures and segmentlengths using the relationships among radii, chords, secants, and tangents of a circle.
  • Use transformations (reflection, rotation, and translation) within coordinate geometry (e.g., reflect points across the y-axis).
  • Use the properties of angles, righttriangles, and similar polygons to solve problems.

Geometry Strategies

  • Set a time each day and a quiet location for math work to be completed at home.
  • Ask to see your child’s math grade on a weekly basis.
  • Make use of tutoring opportunities that may be available at the Intermediate High School. Check with the site for availability and sched- ules.
  • Create a written collection of the definitions, formulas, theorems, and postulates that are used in class, and have your child explain a few of them to you each week.
  • Play a geometric game together like Tangoes (tangrams) or Tetris.
  • Play a logic game like Clue or Rummikub with your child.
  • Work logic, Suduko, or?Kenken puzzles.
  • Watch a mystery with your child, and discuss why the evidence proves or disproves guilt.
  • Calculate the area of a slice of pizza.
  • Look closely at man-made and natural objects to find geometric shapes.For example, buildings, bridges, ships, windows, and towers are all examples of geometric structures. The earth is a large sphere, as are the other planets in the solar system; and fish scales are examples of tessellations.

Union Help Line

A safe and secure school environment is essential to the learning process. An important ingredient in achieving safe and secure schools remains alert eyes and ears. Safety is achieved when an atmosphere exists in which students are comfortable talking with adults about their concerns.

One such tool available for students is a Union Help Line that is open Monday through Friday from 7 a.m. to 9 p.m. to anyone who wants to report a concern. The caller may leave a message so his or her call can be returned, or they may choose not to be contacted. You can also call COPES if this is a mental health emergency.
