Math Extension Problems

 These problems do not specifically fall under CCSS, but are designed for students to bridge concepts and further mathematical understanding

1) Construct an X and Y axis for the graph and create a list of ordered pair representing the graph.  Does this graph represent a Function?  Justify your answer.



If you believe it is a function, change one ordered pair so that it is not.

If you believe it is not a function, change one ordered pair so that it is.

2) Using the fractions 1/2, 1/3, 1/4, 1/5, 1/6, 1/7, 1/8 and 1/9, create a sum with the closest approximation for each of the following roots. (You can use the fractions more than once)
Roots 2-6

3) Using the largest Integer possible, fill in the box to complete the inequality.


Unit Fraction Approximations of Roots

Which one estimates √5 the closest?

4) Using consecutive Integers for each pair of boxes, complete the rational approximations of the square root to make the inequality true.


Open Middle Rational

5) How many fractions can you make below using the whole numbers 1 through 20 so that it is a solution to the inequality?

Open Middle Fraction

What fraction is closest to √2?

What fraction is closest to √3?

6) List 3 points that create a right triangle with an area of 6, staying within the axis provided below (-10 < x < 10, -10 < y < 10).  Rotate your triangle and reflect it across an Axis.  List the three new points.



Write down the steps you used to create your transformation.

Find another set of transformations that gives the same result as your original one.

7) Consider the roots of the first 9 Natural Numbers (√1 to √9), how many of them produce Irrational Numbers?

List them.  Graph their approximate location on a number line.


Explain how you determined where to place them on the graph.


Is √10 Rational or Irrational?  Explain how you know.  Where on the number line would you graph it?

8) List 2 points from a line that satisfies the following (you can use numbers 0-9, but you can only use a number once):

a) Its rate of change must be larger than 2

b) Its y-intercept must be smaller than 3

c) It must share a point with the line described by the rate of change and intercept from a&b


(__,__) and (__,__)


The equation of the two lines is:

y = __x +___

y = __x +___

9) Using triangles to partition a square with side length of 6, create the following probability area models:


1, 1/2, 1/3, 1/4, 1/5, 1/6, 1/7, 1/8, 1/9.

  1. How many triangles are needed to create each?
  2. If you are unable to create some of the models, explain why.
  3. What modifications to the problem is needed to create all 9 probability area models?
