DIVISION OF INTEGERS
Learning goals:
Learning goals:
Learners are able to:
- divide integers with the same sign
- divide integers with different signs
- use calculator to do the division of integers
Content:
Content:
Students:
- divide integers using mental and written strategies
Working Mathematically:
Working Mathematically:
Students:
- investigate, by developing patterns or using a calculator, the rules associated with dividing integers (Reasoning)
Classroom activities:
Classroom activities:
1. Intention (2 mins):
1. Intention (2 mins):
Teacher introduces learning intention.
- Today I will figure out the rule for division of integers with and without the same sign
- So that I can do the division positive integers, negative integers, one positive and one negative integer
- I know I got it when:
- use the kit of positive and negative sign
- do the adding integers maze
2. Video (ICT) (20 mins)
2. Video (ICT) (20 mins)
students will:
- divide a paper in their notebook into 2 columns and then labelling as Give One and Get One.
- watch the video and note down 4-5 key information into the Give One column
- share with at least 4 other students what they noted down in the Give One column and note down the others information in the Get One column.
Teacher.
- turn on the video
- play music to inform students that they need to change the partner
- write the rule of multiplication on the board and do some examples to prove the rules are right.
3. Bingo game (15 mins)
3. Bingo game (15 mins)
- the whole class is divided into 3 groups (4-5 students for each group) and have a competition
- each group will be provided with a big paper containing random positive and negative numbers
- teacher will show the division of 2 integers on the white board
- students will work out the answers as a positive or a negative number and circle the number if they have it on the bingo paper.
- the first group get the row, column or diagonal circled numbers will be the winner
- teacher give a prize (e.g. ice creams) to the winner group
Teachers:
- introduce and set up the activity
- move around, make sure every one is on task

4. Division of integers Maze (15 mins)
4. Division of integers Maze (15 mins)
students will
- work in groups of 3
- find the answer for the division of integers
- match the expression to the correct answer
Teacher:
- hand out the maze
- move around and make sure every one is on task
Homework:
Lesson evaluation questions:
Lesson evaluation questions:
- Were all students on task?
- Could each student know how to work with the kit and figure out the rule of addition
- Did all students participate in the activity?
- Are there alternate (and possibly more effective) ways to collect student responses (e.g. using ICT, multiple choice, etc.)?
