7th Grade Accelerated Course (Please read all the information relative to accelerated course expectations in the above list.)
Topics in the 7th grade accelerated class include: exploring patterns in numbers and geometry; understanding and working with integers and
variables; simplifying expressions; understanding the properties of equality and solving equations; number theory; and geometry. The accelerated
class will not review skills and concepts that students are expected to have mastered in prior years.
Student assignments and assessments include numerous critical thinking and challenge problems. They are expected to work diligently in
and outside of class. They are expected to do every problem on all of their
assignments trying even the most difficult according to information they had in
class or by using their text.
7th Grade Standard Course
Students in both the standard and accelerated courses will use the
text Prealgebra. In addition, all students will learn how to solve equations
through the “Hands On Equations” method. This method introduces students
to solving equations using manipulatives; this process is followed by pictorial
representations and finally through typical symbolic notations. “Hands On
Equations” is very effective in enabling students to visualize and understand
this process which, on the surface, can appear very mechanical. It is a
concrete method that will help students be more successful when they are
exposed to Algebra I in the eighth grade.
Students in the standard classes will study rates, ratios, percents, and proportions; probability and simulations; operations with signed
numbers, generalizations about numbers, and number theory; triangles, polygons and circles. All activities will require students to carefully consider,
practice, write about and apply all of the concepts. They will be expected to learn and to use appropriate mathematical language. Practice with
arithmetic skills is provided within the context of topics that students are studying. However, we encourage parents to work with their children on
number facts, fractions, decimals and percents since these are areas that students should have mastered by the end of the sixth grade. It is
particularly helpful if parents point out the use and importance of mathematics to their children in their everyday lives.
