Warm-up Activity - Human Number Line
•Prepare an index card for each student with an integer on it, include
some with absolute value
•Have them sit in pairs with another card with a greater than symbol on it
(if you flip it, it will be a less than symbol)
•In pairs they need to create two inequalities with the three index cards
•They need to record their two inequalities
•Then each student needs to get into a human number line with their card
-- let them decide if they are in the correct order.
Warm-up Activity - Are you positive or negative?
•Divide the room into two parts, a positive part and a negative part
•Prepare an index card for each student with an integer on it
•Have the students find a partner
•Have them find the products of their two index card
•Have them stand on the side of the room of the sign of their product
•Have the pairs check on each other to decide if everybody is on the
correct side of the room
•Review the rules for multiplying integers
PERFORMANCE ASSESSMENT
INTEGER OPERATIONS - POSTER PROJECT
Specific Statement(s) from the Standard:
I. MATHEMATICAL REASONING
Standard: Apply skills of mathematical representation, communication and
reasoning throughout the remaining for contend strands.
2. Appropriately use examples and counterexamples to make and test
conjectures, justify solutions and explain results.
II. NUMBER SENSE, COMPUTATION AND OPERATIONS
Standard:Use positive and negative rational numbers as fractions, mixed numbers,
decimals or percents and convert among various forms as appropriate.
3. Locate and compare positive and negative rational numbers on a number
line.
Product:
•An informational poster for a mathematics classroom about adding and subtracting
integers or multiplying and dividing integers.
Task Description:
•Poster project
Suppose you work for Math Maniac’s Inc., a company that creates educational
materials for classrooms. Your task is to create an informational poster for a
mathematics classroom about integer operations. Your poster has be about adding
and subtracting integers or multiplying and dividing integers.
Your poster will be graded on the following:
1. A design approved by your teacher
2. Attractiveness
3. Organization
4. Free of grammatical and spelling errors
5. Complete explanations
6. Correct examples for each operation
Special Notes:
Allow one class period for the students to get started on this task, what is not finished
in class is homework due the next day. Provide poster board, colored paper, scissors,
computer access, colored pencils, markers, glue, and rulers as some materials
students can use for the project.
FEEDBACK CHECKLIST
The purpose of the checklist is to provide feedback to the student about his/her work
relative to the content standard. Have the standard available for reference.
