WE will have a NYS Mathematics Test on Wednesday, Thursday and Friday, April 24th, 25th, and 26th. Please make every effort to have your child attend school on those days. We have been reviewing in class and our test will be based on all of the following skills.. . You will need to be competent in the following skills to be successful.
These are the topics that will be on the test:
* Be able to identify all the vocabulary from the unit:
integers, positive numbers, negative numbers,rational numbers,opposite numbers,inequality, absolute value, ordered pair, coordinate plane, x axis, y axis, quadrant, perimeter, area, parallel, length, width.
You should be able to:
If a number is negative or positive in a real life situation. ( temperature, bank acct)
What the absolute value of a number is.
If an inequality is a true statement.
How to write and inequality.
How to draw and label the coordinate plane.
How to list ordered pairs correctly.
How to plot ordered pairs on the coordinate plane.
How to label the quadrants on a coordinate plane.
perimeter ; area; volume; polyhedron; congruent; parallel; perpendicular; surface area; prism; pyramid; vertices; faces; edges; length; width
You should be able to determine the proper name for each polyhedron using its base to help you.
You should be able to determine the number of faces, vertices and edges on any given polyhedron.
You should be able to determine the surface area of a rectangular prism and a triangular prism.
You should be able to effectively use the formula for finding the surface area of triangular and rectangular prisms.

* Be able to use the division algorithm to successfully divide fractions and mixed numbers.
Use your notes and any assignments that we have completed to help you study.
You should know this vocabulary for the unit. It is IMPORTANT that you can speak mathematically and understand the terms we are using.
Prime Number - Any whole number greater than 1 that has only two factors...1 and itself.
Composite Number - Any whole number greater than 1 that has more than 2 factors.
Multiple - A multiple of a number is the product of that number and any whole number
(the multiplication table for that number)
Greatest Common Factor: The greatest whole number that is a common factor of two or more whole numbers.
Least Common Multiple: The lowest whole number greater than 0 that is a common multiple of two or more numbers.
Quotient - The answer to the division problem. ( shown as a remainder, fraction or decimal)
Factor- Any number that is multiplied by another to produce a product
Product- The answer to a multiplication problem.
Greatest Common Factor: GCF
32: 1,2,4,8,16,32 The GCF of 32 and 48 is 16
Least Common Multiple: LCM
5: 5, 10,15, 20, 25, 30, 35 The LCM of 5 and 7 is 35.
7: 7, 14, 21, 28, 35
