Solved Exercises on Temperature Lesson for Kindergarten in Grade 2

Simple temperature concepts, comparison, and basic measurement ideas through these 5 detailed exercises.

Solution: Exercises 1 to 3
1 Simple Temperature Recognition
Exercise 1
Look at this picture of a thermometer. What do you notice? Is it hot or cold?
The red liquid shows 72°F. How do we know if it's hot or cold?
Definition:

Temperature: How hot or cold something is

Thermometer: A tool that measures how hot or cold something is

Hot: Feeling warm

Cold: Feeling cool

Simple Recognition Method:
  1. Look at the red liquid in the thermometer
  2. See how high it goes up
  3. Think about if it feels warm or cool
  4. Decide if it's hot or cold
Red Liquid
High
Feels Like
Warm
Classification
Warm
Step 1: Look at the red liquid

The red liquid is high up in the thermometer

Step 2: Think about what it means

When the red liquid is high, it means things are warm

Step 3: Compare to what you know

72°F is close to room temperature, so it feels warm

Step 4: Say what you think

It's warm!

Temperature: 72°F (Warm)
Final answer:

The thermometer shows 72°F, which is warm.

Applied rules:

• Looking: Always look at the red liquid

• High = Warm: When red liquid is high, it's warm

• Low = Cool: When red liquid is low, it's cool

Tip: Look at how high the red liquid goes
Tip: High red liquid means warm, low red liquid means cool
2 Simple Temperature Comparison
Exercise 2
Which is warmer: 45°F or 60°F? Use your fingers to count and show which is bigger.
Definition:

Comparing: Looking at two things to see which is bigger or smaller

Warmer: Having more heat

Colder: Having less heat

Temperature 1
45°F
Temperature 2
60°F
Bigger Number
60°F
Step 1: Look at both numbers

We have 45°F and 60°F

Step 2: Count on your fingers

Count to 45, then count to 60

Step 3: See which is bigger

60 is bigger than 45

Step 4: Say which is warmer

60°F is warmer than 45°F

60°F is warmer than 45°F
Final answer:

60°F is warmer than 45°F

Applied rules:

• Counting: Use fingers to count and compare numbers

• Bigger Number: Higher numbers mean warmer temperatures

• Smaller Number: Lower numbers mean cooler temperatures

Tip: Use your fingers to count and compare numbers
Tip: Bigger numbers mean warmer temperatures
3 Simple Temperature Change
Exercise 3
In the morning it was 50°F. By afternoon it got warmer. Now it is 65°F. Did it get warmer or cooler?
Definition:

Getting Warmer: Temperature going up

Getting Cooler: Temperature going down

Morning
50°F
Afternoon
65°F
Change
Got Warmer
Step 1: Look at the morning temperature

It was 50°F in the morning

Step 2: Look at the afternoon temperature

Now it is 65°F in the afternoon

Step 3: Compare the temperatures

65°F is bigger than 50°F

Step 4: Decide what happened

Since 65°F is bigger than 50°F, it got warmer

Temperature went up: Got Warmer
Final answer:

It got warmer. The temperature went from 50°F to 65°F.

Applied rules:

• Going Up: When temperature gets bigger, it gets warmer

• Going Down: When temperature gets smaller, it gets cooler

• Compare: Look at both temperatures to see what changed

Tip: If the number gets bigger, it gets warmer
Tip: If the number gets smaller, it gets cooler

4 Simple Temperature Ordering
Exercise 4
Put these temperatures in order from coldest to warmest:
40°F, 75°F, 30°F, 60°F, 50°F
Use your fingers to count and arrange them.
Definition:

Ordering: Putting numbers in order from smallest to biggest

All Temps
40°F, 75°F, 30°F, 60°F, 50°F
Ordered
30°F, 40°F, 50°F, 60°F, 75°F
Step 1: Look at all the numbers

We have: 40°F, 75°F, 30°F, 60°F, 50°F

Step 2: Find the smallest number

30°F is the smallest (coldest)

Step 3: Find the next smallest

40°F is the next smallest

Step 4: Continue counting

Count up: 50°F, then 60°F, then 75°F (warmest)

Step 5: Put them in order

30°F, 40°F, 50°F, 60°F, 75°F

30°F, 40°F, 50°F, 60°F, 75°F
Final answer:

From coldest to warmest: 30°F, 40°F, 50°F, 60°F, 75°F

Applied rules:

• Counting: Use fingers to count and order numbers

• Small to Big: Put smallest numbers first, biggest last

• Compare: Look at each number to find the order

Tip: Use your fingers to count and order the numbers
Tip: Start with the smallest number and go up
5 Simple Daily Temperature Example
Exercise 5
In the morning it was 45°F. During the day it got warmer by 20°F. Then at night it got cooler by 15°F. What was the temperature at night? Use your fingers to help count.
Definition:

Multi-step Problem: A problem with more than one part to solve

Morning
45°F
Got Warmer
+20°F
Got Cooler
-15°F
Night
50°F
Step 1: Start with morning temperature

It was 45°F in the morning

Step 2: Add the warming

During the day it got 20°F warmer

Count: 45, 46, 47... up to 65°F

Step 3: Subtract the cooling

At night it got 15°F cooler

Count backwards: 65, 64, 63... down to 50°F

Step 4: State the final answer

The temperature at night was 50°F

45°F + 20°F - 15°F = 50°F
Final answer:

The temperature at night was 50°F

Applied rules:

• One Step at a Time: Solve problems in the order they happen

• Counting: Use fingers to help with addition and subtraction

• Adding: When temperature goes up, add the number

• Subtracting: When temperature goes down, subtract the number

Tip: Use your fingers to count when adding or subtracting
Tip: Do one step at a time to avoid confusion

Questions & Answers

Question: I don't understand how to read a thermometer. Why does the red go up and down?

Answer: Great question! A thermometer is like a magic stick that shows how hot or cold it is:

  • The red part inside is special liquid that moves up when it's warm
  • The red part moves down when it's cool
  • When the red goes high up, it means things are warm
  • When the red stays low down, it means things are cool

Think of it like this: when you're warm, you might jump up high, and when you're cold, you might curl up small. The red liquid does the same thing!

Always look at where the red liquid stops!

Question: My child is struggling with temperature comparison. How can I help them understand which is hotter or colder?

Answer: Here are some fun ways to help your child:

  • Use their fingers: Have them count to compare numbers
  • Make it visual: Use toys to represent different temperatures (red toys for hot, blue for cold)
  • Real examples: "Ice cream is cold (32°F)" vs "Hot cocoa is warm (120°F)"
  • Physical actions: Jump up for warm, curl up for cold

Visual aids work best for young children. You could draw thermometers and let your child color-code different temperature ranges. Make it a game - children learn better when they're having fun!

Keep it simple and use lots of repetition!

Question: Are there any fun activities I can do at home to teach temperature concepts?

Answer: Absolutely! Here are engaging activities for kindergarteners:

  • Temperature Feel Game: Touch different items (ice cube, warm water, room temperature objects) and sort them as hot or cold
  • Weather Dress-Up: Show different temperatures and have them pick appropriate clothing
  • Thermometer Drawing: Let them draw thermometers with different red liquid levels
  • Temperature Charades: Act out being hot (fan themselves) or cold (shiver)

You can also incorporate temperature into daily routines: "The bath water is warm!" or "The refrigerator is cold!" This connects learning to real life.

Keep activities short (5-10 minutes) and make them playful!
