Addition Word Problems Challenge

The video tutorial covers different types of addition problems, focusing on 'some plus some more' and 'part plus part' problems. It provides examples to illustrate these concepts, such as determining the number of girls in a class and the number of chocolate candies in a box. The tutorial emphasizes the importance of verifying answers for reasonableness and offers both algebraic and arithmetic methods for solving problems. The lesson concludes with instructions for an assignment.

What is the main difference between 'some plus some more' and 'part plus part' problems?

• The type of objects being added.

• The wording of the problem.

• The total amount being calculated.

• The method of solving the problem.

In Example 3, if there are 24 students in total and 14 are boys, how many are girls?

• 8

• 10

• 12

• 14

What should you do if a problem does not provide a specific number?

• Guess the number.

• Use a placeholder variable.

• Ask the teacher.

• Skip the problem.

Why is it important to justify your answer?

• To ensure the answer is reasonable.

• To show your work to the teacher.

• To make the problem more complex.

• To practice more problems.

If you mistakenly add instead of subtracting in Example 3, what might be a possible incorrect answer?

• 14

• 38

• 24

• 10

In Example 4, if there are 35 candies in total and 19 are strawberry, how many are chocolate?

• 14

• 16

• 18

• 20

What is the first step in solving the algebraic equation c + 19 = 35?

• Multiply both sides by 19.

• Subtract 19 from both sides.

• Add 19 to both sides.

• Divide both sides by 19.

Why is it necessary to double-check your work?

• To practice more problems.

• To impress the teacher.

• To make the problem more challenging.

• To find any possible mistakes.

What should you do if your answer does not seem reasonable?

• Recheck your calculations.

• Ask a friend for help.

• Submit it anyway.

• Skip the problem.

In Example 4, what is the final step to ensure your answer is correct?

• Adding the chocolate and strawberry candies to see if they total 35.

• Multiplying the chocolate candies by 2.

• Rewriting the problem.

• Subtracting the strawberry candies from the total.
