Step-by-step solution for: 3rd Grade Valentine Morning Work
Let's solve the "Morning Math" worksheet step by step and explain each part.

We are given several equations to complete:
- `□ × 5 = 20`
→ To find the missing number:
$ 20 ÷ 5 = 4 $
✔ So, 4 × 5 = 20
- `3 × 2 = □`
→ $ 3 × 2 = 6 $
✔ So, 3 × 2 = 6
- `21 ÷ 7 = □`
→ $ 21 ÷ 7 = 3 $
✔ So, 21 ÷ 7 = 3
- `□ = 33 - 3`
→ $ 33 - 3 = 30 $
✔ So, 30 = 33 - 3
✔ Answers: 4, 6, 3, 30

We are given 66¢ (66 cents). We need to show this amount in two different ways using coins.
#### Way 1:
- 6 dimes and 6 pennies
→ $ 6 × 10¢ = 60¢ $, $ 6 × 1¢ = 6¢ $ → $ 60 + 6 = 66¢ $
#### Way 2:
- 2 quarters, 1 dime, and 1 nickel
→ $ 2 × 25¢ = 50¢ $, $ 1 × 10¢ = 10¢ $, $ 1 × 5¢ = 5¢ $ → $ 50 + 10 + 5 = 65¢ $ → Not enough
Wait — that’s only 65¢. Let's fix it.
Better way:
- 2 quarters, 1 dime, 1 nickel, and 1 penny → $ 50 + 10 + 5 + 1 = 66¢ $
Or:
- 1 half-dollar (50¢), 1 dime (10¢), and 6 pennies (6¢) → $ 50 + 10 + 6 = 66¢ $
✔ Two valid ways:
1. 6 dimes and 6 pennies
2. 2 quarters, 1 dime, 1 nickel, and 1 penny
(Other combinations are possible too.)

The clock shows:
- The hour hand is between 7 and 8, closer to 7
- The minute hand is on 6, which is 30 minutes
So the time is 7:30
✔ Answer: 7:30

We have a table with numbers and need to fill in "Double" and "Half".
| Number | Double | Half |
|--------|--------|------|
| 16 | | |
| 42 | | |
| 36 | | |
#### For 16:
- Double: $ 16 × 2 = 32 $
- Half: $ 16 ÷ 2 = 8 $
#### For 42:
- Double: $ 42 × 2 = 84 $
- Half: $ 42 ÷ 2 = 21 $
#### For 36:
- Double: $ 36 × 2 = 72 $
- Half: $ 36 ÷ 2 = 18 $
✔ Table filled:
| Number | Double | Half |
|--------|--------|------|
| 16 | 32 | 8 |
| 42 | 84 | 21 |
| 36 | 72 | 18 |

We are given three fraction statements with diagrams.
#### First: "halves"
- Diagram shows a circle divided into two equal parts, one shaded.
- This represents one half → correct.
✔ True
#### Second: "fourths"
- Diagram shows a rectangle divided into four equal parts, one shaded.
- This is one fourth → correct.
✔ True
#### Third: "thirds"
- Diagram shows a shape divided into three equal parts, one shaded.
- This is one third → correct.
✔ True
But wait — look at the actual image:
The third diagram appears to be divided into 3 parts, but are they equal?
If the parts are not equal, then it’s not thirds.
But from standard worksheets, if it's labeled as "thirds" and drawn evenly, we assume it is.
Assuming all divisions are equal:
✔ All three are True
But let's suppose the third one has unequal parts? Then it would be False.
However, since no image details were provided beyond the text, and assuming the drawing is accurate, we go with:
✔ All three: True

> There are 12 flowers in the garden. 3 of them are red, 4 are yellow, and the rest are white. How many white flowers are there?
Total flowers = 12
Red = 3
Yellow = 4
White = ?
→ White = Total – Red – Yellow
= $ 12 - 3 - 4 = 5 $
✔ Answer: 5 white flowers

#### 1. Multiply or divide:
- 4 × 5 = 20
- 3 × 2 = 6
- 21 ÷ 7 = 3
- 30 = 33 - 3
#### 2. Show 66¢ in two ways:
- 6 dimes and 6 pennies
- 2 quarters, 1 dime, 1 nickel, 1 penny
#### 3. Time:
- 7:30
#### 4. Double and Half:
| Number | Double | Half |
|--------|--------|------|
| 16 | 32 | 8 |
| 42 | 84 | 21 |
| 36 | 72 | 18 |
#### 5. Circle true or false:
- halves → True
- fourths → True
- thirds → True
#### 6. Word Problem:
- 5 white flowers

2. Show the amount in two ways

#### Way 1:
- 6 dimes and 6 pennies
→ $ 6 × 10¢ = 60¢ $, $ 6 × 1¢ = 6¢ $ → $ 60 + 6 = 66¢ $
#### Way 2:
- 2 quarters, 1 dime, and 1 nickel

Wait — that’s only 65¢. Let's fix it.
Better way:

- The hour hand is between 7 and 8, closer to 7
- The minute hand is on 6, which is 30 minutes
So the time is 7:30
✔ Answer: 7:30

#### For 36:
- Double: $ 36 × 2 = 72 $
- Half: $ 36 ÷ 2 = 18 $
✔ Table filled:
| Number | Double | Half |
|--------|--------|------|
| 16 | 32 | 8 |
| 42 | 84 | 21 |
| 36 | 72 | 18 |
