Solved Exercises on Understanding Weight Watchers Points in Grade 1

Master points calculation and comparison: comparing points, calculating daily totals, solving point-based problems through these 3 detailed exercises.

Solution: Exercises 1 to 3
1 Comparing Points
Exercise 1
Sarah ate breakfast (3 points), lunch (4 points), and dinner (5 points). How many points did she eat today? Did she eat more points for lunch or dinner?
Definition:

Points: A number system used to track food choices. Adding points shows total consumption.

Points calculation method:
  1. Identify points for each meal
  2. Add points together for daily total
  3. Compare individual meals to see which has more points
Breakfast
3 points
Lunch
4 points
Dinner
5 points
Step 1: Identify points for each meal

Breakfast = 3 points, Lunch = 4 points, Dinner = 5 points

Step 2: Calculate daily total

3 + 4 + 5 = 12 points

Step 3: Compare lunch and dinner

Lunch = 4 points, Dinner = 5 points, so 4 < 5

Step 4: Answer the question

Sarah ate 12 points total. Dinner had more points than lunch.

Total: 3 + 4 + 5 = 12 points
Final answer:

Sarah ate 12 points today. She ate more points for dinner (5) than for lunch (4).

Applied rules:

• Addition: Add points from different meals to get total

• Comparison: Compare numbers to see which is greater

• Points system: Higher numbers mean more points

2 Daily Points Tracking
Exercise 2
Tom tracked his points for 3 days: Day 1: 15 points, Day 2: 12 points, Day 3: 18 points. On which day did he eat the most points? The least?
Definition:

Daily Tracking: Recording points each day to monitor eating habits.

Days
Day 1: 15, Day 2: 12, Day 3: 18
Order
12 < 15 < 18
Results
Least: Day 2, Most: Day 3
Step 1: List all daily points

Day 1 = 15 points, Day 2 = 12 points, Day 3 = 18 points

Step 2: Compare and order numbers

12 < 15 < 18, so Day 2 < Day 1 < Day 3

Step 3: Identify highest and lowest

Highest: Day 3 (18 points), Lowest: Day 2 (12 points)

Highest: Day 3 (18 points), Lowest: Day 2 (12 points)
Final answer:

Tom ate the most points on Day 3 (18 points) and the least on Day 2 (12 points).

Applied rules:

• Tracking: Record points regularly to monitor patterns

• Numerical comparison: Compare multiple measurements

• Pattern recognition: Notice trends over time

3 Points Budget Calculation
Exercise 3
Lisa gets 20 points each day. Today she ate 8 points for breakfast and 6 points for lunch. How many points does she have left for dinner?
Definition:

Points Budget: The total number of points allowed per day. Leftover points = Total - Used.

Daily Budget
20 points
Used Points
8 + 6 = 14 points
Remaining
20 - 14 = 6 points
Step 1: Identify daily budget

Lisa gets 20 points each day

Step 2: Calculate points already eaten

Breakfast (8) + Lunch (6) = 14 points

Step 3: Set up the calculation

Remaining points = Daily budget - Points used

Remaining points = 20 - 14

Step 4: Calculate the result

20 - 14 = 6 points

Step 5: State the final answer

Lisa has 6 points left for dinner

20 - (8 + 6) = 6 points remaining
Final answer:

Lisa has 6 points left for dinner (20 - 14 = 6).

Applied rules:

• Subtraction: Taking away used points from total

• Budgeting: Managing points within daily limit

• Units: Keep units consistent throughout calculation

High Points: Foods worth 7+ points

Problem-solving strategies:
  1. Read carefully: Understand what the problem asks
  2. Find key info: Identify important numbers and words
  3. Choose operation: Decide if adding, subtracting, or comparing
  4. Solve step-by-step: Work through the problem methodically
  5. Check answer: Make sure it makes sense
Tip 4: Use a chart to track points each day.
Tip 5: Practice with simple addition and subtraction.
Tip 6: Always check if your answer fits the context.

Real-world applications: Budgeting, resource management, planning meals.
Advanced concepts: Multiplication for multiple servings, fractions for portions.
Important facts to remember:

• Points measure food consumption

• Addition combines points

• Subtraction finds remaining points

• Higher numbers mean more points

• Budgeting helps manage resources

Questions & Answers

Question: I don't understand how to add points together. Can you explain how points calculation works?

Answer: Points calculation is just like adding numbers:

  • If you eat breakfast worth 3 points and lunch worth 4 points, add them: 3 + 4 = 7 points total
  • Think of points like small pieces of paper - if you have 3 papers and get 4 more, you have 7 papers total
  • We add points from different foods to find the total for the day

Visual trick: Draw circles for each point and count them all together.

Example: Breakfast: 2 points, Snack: 3 points → Total: 2 + 3 = 5 points.

Question: When I need to find how many points I have left, what's the best way to calculate it?

Answer: Here's the method for finding remaining points:

  1. Know your daily budget (for example, 20 points)
  2. Add up points you've already eaten (for example, 8 + 6 = 14 points)
  3. Subtract: Daily budget - Points eaten = Points remaining
  4. So: 20 - 14 = 6 points left

You can think of it like money - if you have $20 and spend $14, you have $6 left.

Memory tip: "Take away what you used to see what's left!"

Question: I sometimes get confused with word problems about points. How do I know what to do?

Answer: Points problems usually involve addition or subtraction. Here's a strategy:

  1. Read slowly: Understand what the problem is asking
  2. Find numbers: Circle or underline the points mentioned
  3. Look for keywords: "total" (addition), "remaining/left" (subtraction), "more than" (comparison)
  4. Draw a picture: Visualize the situation
  5. Solve step by step: Write out the math

Example: "Max ate 5 points for breakfast, 6 for lunch. How many total?" Keywords: "total" = addition. So Max: 5 + 6 = 11 points.
