1. Write the number sixty-nine three more times. How many digits are on the line?

Instructions: You're to write "69" four times in total (once already written, then three more). Each "69" has two digits.

So:
- 69 → 2 digits
- 69 → 2 digits
- 69 → 2 digits
- 69 → 2 digits

Total digits:
$$
4 \times 2 = 8 \text{ digits}
$$

✔ Answer: 8 digits

2. Louisa made a chain of paper clips. She used 6 large paper clips and 6 small paper clips. Draw a picture and write a number sentence.

Step 1: Draw a picture
You can draw 6 large clips (maybe as big rectangles) and 6 small clips (smaller rectangles), alternating or in a line.

Step 2: Number sentence
Add the large and small clips together:

$$
6 + 6 = 12
$$

How many paper clips did Louisa use?
$$
6 + 6 = 12 \text{ paper clips}
$$

✔ Answer:
- Number sentence: $6 + 6 = 12$
- Total paper clips: 12

3. How many dimes and pennies will you need to buy the toy car?

The toy car costs 85¢.

We know:
- 1 dime = 10¢
- 1 penny = 1¢

To make 85¢ using dimes and pennies:
- Maximum dimes: $85 ÷ 10 = 8$ dimes = 80¢
- Remaining: $85 - 80 = 5¢$, so 5 pennies

✔ Answer:
- 8 dimes
- 5 pennies

(You could also say 7 dimes and 15 pennies, but usually we use the fewest coins. So 8 dimes and 5 pennies is best.)

4. Finish the pattern.

Pattern:
Parallelogram, Triangle, Triangle, Circle, Parallelogram, Triangle, ____, ____

Let’s look at the sequence:
1. Parallelogram
2. Triangle
3. Triangle
4. Circle
5. Parallelogram
6. Triangle
7. ?
8. ?

Now, check if there's a repeating pattern.

Grouping:
- (Parallelogram, Triangle, Triangle, Circle) — this repeats?

But wait:
First group:
- 1: Parallelogram
- 2: Triangle
- 3: Triangle
- 4: Circle

Then:
- 5: Parallelogram → same as #1
- 6: Triangle → same as #2
- 7: ??? → should be same as #3 → Triangle
- 8: ??? → should be same as #4 → Circle

So the pattern repeats every 4 shapes.

✔ Answer:
- 7th shape: Triangle
- 8th shape: Circle

5. Christopher’s receipt at the classroom store:

| Item | Cost |
|--------|------|
| Milk | 42¢ |
| Beans | 31¢ |
| Total | ? |

#### Step 1: Add the amounts
$$
42¢ + 31¢ = 73¢
$$

So, he spent 73¢.

#### Step 2: How many dimes is that?
Each dime = 10¢
$$
73 ÷ 10 = 7 \text{ dimes} \quad (\text{with } 3¢ \text{ left})
$$

So, 7 dimes and 3 pennies.

#### Step 3: How many pennies is that?
73¢ = 73 pennies

✔ Answers:
- Total money spent: 73¢
- Dimes: 7
- Pennies: 73

✔ Final Answers Summary:

1. 8 digits
2. Number sentence: 6 + 6 = 12, 12 paper clips
3. 8 dimes, 5 pennies
4. Triangle, Circle
5. Total: 73¢, 7 dimes, 73 pennies
