# Math Assessment on Integers and Rational Numbers

Dear Parents,

We have an up-coming assessment on Integers and Rational Numbers. Students will be tested on the following topics:

1. Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge); Use positive and negative numbers to represent quantities in real-world contexts, explaining the meaning of 0 in each situation. (IXL: M.1)
2. Find and position integers and other rational numbers on a horizontal or vertical number line diagram. (IXL: M.2, M.4, P.6)

3. Students understand absolute value as the distance from zero and recognize the symbols | | as representing absolute value. (IXL: M.3, P.3)

4. Recognize opposite signs of numbers as indicating locations on opposite sides of 0 on the number line; recognize that the opposite of the opposite of a number is the number itself, e.g., – (–3) = 3, and that 0 is its own opposite (IXL: M.3)

5. Interpret statements of inequality as statements about the relative position of two numbers on a number line. For example, interpret –3 > –7 as a statement that –3 is located to the right of –7 on a number line oriented from left to right. (IXL: M.5, P.1)

6. Understand ordering and absolute value of rational numbers. (IXL: M.5, M.6, P.1, P.2, P.3, P.6)

7. Write, interpret, and explain statements of order for rational numbers in real-world contexts. For example, write –3oC > –7oC to express the fact that –3oC is warmer than –7oC.

8. Find and position pairs of integers and other rational numbers on a coordinate plane. (IXL: X.1, X.2, X.4)

9. Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane; recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes. (IXL: X.3)

10. Solve real-world and mathematical problems by graphing points in all four quadrants of the coordinate plane. Include use of coordinates and absolute value to find distances between points with the same first coordinate or the same second coordinate. (IXL: X.5)

11. Applying their knowledge to real-life situations (word problems).

I have listed specific IXL practice sections connected with each topic above.

Section 3 will have their assessment on Monday, December 11th.

Sections 1, 2 & 4 will have their assessment on Tuesday, December 12th.

Thank you!
