As part of the pre-assessment, you will complete a Diagnostic Worksheet containing 5 simple problems involving percentage, base, and rate. This activity will help you activate your prior understanding and identify any areas of difficulty related to the topic.
To help you activate prior knowledge, set learning goals, and reflect on your learning progress throughout the lesson, you will fill out a K-W-L Chart.
Guide Questions:
K (Know): “What do I already know about percentage, base, and rate?”
W (Want to Know): “What questions do I still have about these terms?”
You will complete the L (Learned) part at the end of the lesson.
After completing the diagnostic activities, each group of 5 members will gather to compare their answers. The goal is to learn from each other’s solutions, recognize patterns, and deepen your understanding of percentage, base, and rate through discussion.
Guide Questions for Group Discussion:
Are our answers the same or different?
How did you solve the problems?
What patterns do you notice about percentages, bases, and rates?
What have you learned from each other’s answers?
Note-Taking Activity: Once your group has finished discussing, you will work together to write short notes in your notebooks. These notes will help you remember the important concepts.
You will practice solving word problems involving Percentage (P), Base (B), and Rate (R) by applying the appropriate formulas. You will collaborate in dyads or triads to work through problems and share your reasoning with one another.
Questions:
1. Finding the Percentage (P = B × R)
“45 elderly respondents said they sometimes worry about medical expenses. If there were 60 total respondents, what percent of them worry sometimes?”
2. Finding the Base (B = P ÷ R)
“60% of the elderly respondents said they take maintenance medicine daily. If that’s 36 people, how many total respondents were there?”
3. Finding the Rate (R = P ÷ B)
“12 elderly people said they experience joint pain. If there were 48 respondents, what percentage is that?”
In this group activity, you will work together to create a simple survey focused on the needs of elderly people in three key areas: transportation, budgeting, and healthcare. This will help you understand how to ask good questions, work respectfully, and connect your learning in math to real-world topics.
This activity helps you prepare to analyze data using percentage, base, and rate. The questions you make will be answered using "Always," "Sometimes," or "Never", and later, you will use these answers to calculate how many people chose each response — and from there, find the percentage (P), base (B), and rate (R).
Think about what elderly people experience in their daily lives.
Guide Questions:
Do they have access to transportation?
Do they struggle with budgeting or buying things they need?
Do they regularly go to health check-ups or take medicine?
Choose the best 10 ideas and turn them into short, clear questions. All questions should be answerable by “Always,” “Sometimes,” or “Never.”
These answers will help you gather data for calculating:
Base (B): Total number of respondents
Percentage (P): Number of people who gave a specific answer
Rate (R): The part over the whole (expressed as a percent)
Example Question:
“Do you have someone to assist you when you go to the doctor?”
If 15 out of 30 people say “Always,” then:
P = 15, B = 30, R = 15 ÷ 30 = 0.50 = 50%
Each group shares their drafted questions. Then, the class reflects by discussing:
Guide Questions:
Are these questions respectful?
Are they easy for an elderly person to understand?
Is the language simple and not too long?
Are there any questions that feel too personal or confusing?
Are the questions can be answerable by always, sometimes, and never?
Each group rewrites their final survey questions on a clean sheet or slide. They check if their questions:
Use clear and respectful language
Match the theme (transportation, budgeting, healthcare)
Can be answered easily by a senior citizen
Checklist
This checklist helps teachers accurately determine students' starting points in their learning journey. By using diagnostic worksheets and K-W-L charts, teachers can identify prior knowledge, misconceptions, skill levels, and areas needing support. It ensures that instruction is better targeted, allowing lessons to be adjusted to meet students’ actual needs. Ultimately, it promotes more effective teaching and supports meaningful student progress.
Drafting and Finalizing a survey checklist is essential for students engaging with senior citizens. It ensures that the survey is clear, organized, and thoughtful, promoting the collection of meaningful responses. Through this process, students develop values such as empathy and patience by understanding and respecting the perspectives of senior citizens. It also fosters responsibility and effective communication skills, as students learn to create questions that are purposeful and considerate.
Peer and Self-Assessment are tools for promoting reflective learning and collaboration among students. Through self-assessment, students evaluate their own work, identifying strengths and areas for improvement. This process fosters critical thinking and self-awareness, as they take ownership of their learning journey. By reflecting on their progress, they develop a growth mindset and the ability to set realistic goals for personal improvement.
Peer assessment, on the other hand, encourages students to provide constructive feedback to one another. This interaction enhances communication skills, builds a sense of responsibility, and nurtures mutual respect. It also allows students to gain diverse perspectives, improving their ability to evaluate work objectively. Together, self and peer assessment not only promote academic growth but also cultivate interpersonal skills and a collaborative mindset.
