A) 

This area model is showing one way to solve 

Based on the calculations, select the answer to 

A) The quotient would be 322 because 11 was multiplied by 300. The answer 22 was written in the tens and the ones place.

B) The quotient would be 392 because 11 was multiplied by 300, 90, and 2. The products can be added together to equal the original dividend of 4,312

The quotient would be 392 because 11 was multiplied by 300, 90, and 2. The products can be added together to equal the original dividend of 4,312

If each dot represents 8 what would a division equation be

There are 5 dots in each row each dot equals 8. First identify how many are in each row 8x5=40. Then multiply by how many rows you have 40x6=240.

Then you can create a division sentence

240/6=40

Student A says to check 5,487/5=1,097 R 2 you take 1,097x5

Student B says you have to take the quotient multiply it by the divisor and add in the remainder.

Which student is correct?

Student B. In order to accurately check your answer. Your multiplication must equal your dividend. You can't forget to add in any remainder.

1,097x5= 5,485

5,485+2=5,487

5,487 is our dividend.

Calculate 4,956/13

Then express the remainder as a fraction in simplest form. (Remember: the denominator will be what your divisor was (13))

4,956/13= 381 R3

A classroom of 12 students had 145 stickers to share.

How many stickers does each student receive?

Each student receives 12 stickers.

145/12= 12 R1

Since you cannot split 1 sticker between 12 students you drop the remainder.

FINAL JEOPARDY

Work with your team to solve the problem.

You must:

1. Estimate the answer.
2. Find the exact quotient.
3. Determine if there is a remainder.
4. Explain how you would check your answer using multiplication.

A treasure chest contains 27,005 gold coins.

The coins are divided equally among 55 pirates.

Part 1

Estimate how many coins each pirate will receive.

Part 2

Find the exact quotient.

Part 3

Will there be any coins left over?

Part 4

Show how you would check your answer using multiplication.

✅ Possible Estimates

Option A: Round Both Numbers

27,005 ≈ 27,000

55 ≈ 60

27,000 ÷ 60 = 450

Estimated Quotient:

About 450 coins

Option B: Round Divisor Down

27,005 ≈ 27,000

55 ≈ 50

27,000 ÷ 50 = 540

Estimated Quotient:

About 540 coins

Option C: Keep the Divisor

27,005 ≈ 27,500

27,500 ÷ 55 = 500

Estimated Quotient:

About 500 coins

Teacher Discussion

Ask:

Why might different groups get different estimates?

• We rounded differently.
• Some groups rounded 55 up.
• Some groups rounded 55 down.
• Some groups left 55 unchanged.

Explanation

All three estimates are reasonable because they help predict the exact quotient. The exact answer should fall somewhere near these estimates.

✅ Exact Answer

27,005 ÷ 55 = 491

There is no remainder.

✅ Check Using Multiplication

491 × 55

491 × 5 = 2,455

491 × 50 = 24,550

24,550 + 2,455 = 27,005

Since the product equals the dividend:

✅ The quotient is correct.

🌟 Final Discussion Question

Defend Your Strategy

Which estimate do you think was the most accurate and why?

• The estimate of 500 because it is closest to 491.
• The estimate of 540 because 55 rounds nicely to 50.
• The estimate of 450 because rounding up to 60 made the division easier.

Explanation

Different estimation strategies can be reasonable. The goal of estimation is not to find the exact answer. The goal is to find an answer that is close enough to help us predict whether our final answer makes sense. 🏴‍☠️💰
