Using Bar Models to Solve Division Problems

This video tutorial teaches how to solve division problems using bar models and multiplication knowledge. It begins with an introduction to the concept, followed by examples using flowers, chairs, crayons, and pencils to illustrate the use of bar models in division. Common mistakes in division are highlighted, and the importance of understanding the problem context is emphasized. The lesson concludes with a summary of the key points covered.

If you know that 8 times 2 equals 16, how can this help you solve 16 divided by 8?

• It shows that division is unrelated to multiplication.

• It indicates that division is not possible.

• It helps you find the missing factor in division.

• It suggests that division is always larger than multiplication.

In the example with 24 flowers in 3 vases, what does the bar model help illustrate?

• The number of flowers in one vase.

• The total number of vases.

• The relationship between addition and subtraction.

• The connection between multiplication and division.

What is a common mistake when solving word problems involving division?

• Ignoring the total number given.

• Using a bar model.

• Dividing numbers correctly.

• Multiplying numbers without understanding the problem.

In the problem with 18 chairs in 3 rows, what is the correct equation to find the number of chairs per row?

• 18 minus 3

• 18 plus 3

• 18 times 3

• 18 divided by 3

How does the bar model help in solving the problem of 48 pencils packed in 6 boxes?

• It multiplies the number of boxes.

• It helps divide the pencils equally among boxes.

• It adds more pencils to the total.

• It shows the total number of pencils.
