Math - Integers Unit Plan
Subject & Topic
Math – Integers
Students will be able to…
Recognize, understand and manipulate integers using addition and subtraction.
Rationale
Integers – positive and negative numbers, are a part of everyday life. It’s important that students have an understanding of integers and how they can be manipulated because they are present in a number of real world situations including banking.
Provincial Learning Outcomes
A6 Demonstrate an understanding of addition and subtraction of integers, concretely, pictorially, and symbolically.
Draft Curriculum
Big Idea: Understanding whole number addition and subtraction helps us make sense of and do these operations with fractions and integers.
Culminating Task
At the end of the unit the students will write a test to demonstrate what they have learned.

Outcomes:

SWBAT identify and understand integers
Activities:

Intro to integers – notes taken in Math Journal

Brainstorm: Where have we seen positive and negative numbers? (temperature, elevation, money)

Introduce the number line – give students their own number lines

Assign MP pg 61
Assessment:

Math - Integers Unit Plan
Activities:

Mark math from previous day – record scores

Math Journal: Compare temperatures (live from ipad weather) of five different places.
Plot them on the number line. Which are greater than 0 degrees? Order them from hottest to coldest.

Assign MP pg 63
Assessment:

Mark math homework the following class.
Criteria:

Student has passed (mark above 50%)
Lesson Three – Adding Integers
Outcomes:

Students will be able to manipulate integer tiles to solve an addition equation.
Activities:

Introduce Addition of integers using integer tiles


Solve problems together using integer tiles
Give problems for students to solve using integer tiles

Assign MP pg 119
Assessment:

Formative: Observations

Assessment of learning: Marking Math
Criteria:

Students are correctly manipulating integer tiles to arrive at the correct answer

Student has passed the homework (above 50%)
Lesson Four – Adding Integers
Outcomes:

Students will be able to solve addition equations without integer tiles.
Activities:

Brainstorm observations about addition of integers ( two positives = positive, two negatives = negative, positive and negative = the difference positive or negative)

Card Game – In partners, students will have one deck of card. The deck is split evenly between the two students. Black cards are positive; Red cards are negative. The students flip one card at a time. The first student to answer the equation correctly gets to keep the cards.

Worksheet – Practice Addition
Assessment:

Observation of card game

Mark Worksheet
Criteria:

Students are understanding and able to play the card game

Students can answer the worksheet correctly (pass)
Lesson Five – Subtracting Integers
Outcomes:

SWBAT manipulate integer tiles to solve a subtraction equation.
Activities:

Introduce subtraction of integers using integer tiles


Solve problems together using integer tiles
Solve problems individually using integer tiles

Assign MP pg 121
Assessment:

Formative: Observation

Assessment of learning: Homework Mark
Criteria:

Observation: Students are able to solve subtraction equations using integer tiles

Student passed homework (50%)
Lesson Six – Subtracting Integers
Outcomes:

SWBAT solve subtraction equations without using integer tiles
Activities:

Brainstorm strategies for subtraction (positive minus positive = regular subtraction, negative minus positive is negative, positive minus negative is positive, negative minus negative is neg or pos)

Card game (same as previous but with subtracting)

Worksheet
Assessment:

Observation of game

Collect marks from worksheet
Criteria:

Students are able to subtract integers in the card game without using the manipulative

Students pass worksheet (50%)
Lesson Seven – Review and Pre-Test
Outcomes:

SWBAT understand and manipulate integers (addition and subtraction)
Activities:

Review Game (Whole class)


Give Pre-Test
Students can practice addition and subtraction by playing a card game with a friend if they are done the pre-test

Go over the answers of the pre-test (so that they can study at home with the right answers)
Assessment:

Formative – observation

Pre-Test Results
Criteria:
 Students are “getting it” during class game

All students successfully complete the pre-test
Lesson Eight – Test
Outcomes:

SWBAT demonstrate their learning from this unit on a test
Activities:

Test writing period
Assessment:

Summative – record marks
Criteria:

All students pass the test (some adaptations will be required)
