Middle Level ICT integration
- this PhET simulation can accommodate the needs and the diverse learning style of the students as they can learn at their own pace and in the way they want to learn.
- it enables the students to visualize and interact with the abstract concepts.
- makes learning more engaging where learners can explore and experiment safely and efficiently within the virtual environment.
- available in online, making it accessible to all learners all around the world regardless of financial status and resources.
Subject: Math
Class: IV
Chapter: Unit 3, chapter 1
Topic: Number line: Integers
Activity: Exploring Integers on the Number line
Objectives
By the end of the lessons, student should be able to,
1.
identify the position of integers correctly on a
number line without help from peers (Cognitive).
2.
express
their thoughts and opinions about relevance of number line integers in
real-life situations (affective).
3.
participate in PhET simulation activities actively
without help from teachers (Psychomotor).
Teaching Learning Materials: Laptops, computers and
mobile phones with access to PhET simulation.
Lesson introduction:
·
Begin the lesson by asking students if they have
ever heard of or worked with number lines before. Prompt them to share their
prior knowledge and experiences.
·
Introduce the concept of number line integers, explaining
that they represent positive and negative whole numbers and zero on a line.
·
Share real-life examples where understanding
integers is important, such as temperature, money, and positions on a
coordinate plane.
Lesson Development:
·
Demonstrate on how to use PhET simulations to
explore integers on the number line. Explain the different features and tools
available in the simulation.
·
Guide students through a step-by-step
exploration of the number line using the simulations. Start with simple
examples and gradually increase the complexity.
·
Encourage student to actively participate by
placing integers on the number line, adjusting values, and observing changes in
absolute values.
·
Facilitate class discussions to deepen
understanding, asking questions like “what happens when we move to the right or
left on the number line?” Or “how can we determine the absolute value of an
integer?”
Activity: Group Work
Purpose: to
explore integers on the number line and know their positions using PhET
simulations.
Instructions:
v
Use the Google engine and type in
phet.colardo.edu
v
Click on simulations and then select all Sims.
v
Click on the subject that you are going to
learn, for our case its math, so select math.
v
Then select “Number line: Integers ”
Click the play button
Click on the picture shown above in the rectangle and drag above into the ocean picture.
During the PhET simulations on number line integers, student should solve those questions in a group:
1.
Can you place the integer -5 on the number line?
How about 3?
2. What happens when you move to the right or left or
up and down on the number line? How does it relate to positive and negative
values?
3.
Can you identify the absolute value of -8? How about
10?
4. What happens to absolute value of an integer
when you move it further away from zero on the number line?
5. How can you represent the concept of zero on the
number line? What does it mean in terms of positive and negative values?
Follow up:
After completion of the exploration and discussing the
questions in a group, ask each group member to present their discussions and
finding to the whole class. During their presentation teacher shall assess
their level of understanding, supplement, and provide necessary feedbacks and
corrections.
Lesson closure:
v
Summarize the key concepts covered in the
lesson, emphasizing the importance of understanding number line integers and
their relevance in real-life situations.
v
Encourage student to continue exploring number
line integers independently or with help of the PhET simulations.
v
Assign practice exercises or activities to
reinforce the concepts learned during the lesson.
