Estimating and Solving Word Problems

This video tutorial teaches how to solve word problems using real objects and paper representations. It covers the distinction between division and subtraction, estimating costs using multiplication, and understanding grouping and remainders. The tutorial emphasizes practical problem-solving techniques and estimation strategies to ensure answers are reasonable.

What is the first step in solving word problems using real objects?

• Estimate the answer

• Ignore the problem

• Use paper pieces to represent objects

• Directly calculate the answer

In the balloon example, what mathematical operation is used to share balloons among friends?

• Multiplication

• Division

• Addition

• Subtraction

When Jasmine gives away some pineapples, which operation helps determine how many are left?

• Subtraction

• Addition

• Multiplication

• Division

How can you estimate the result of 13 minus 4 using compatible numbers?

• Round 4 to 3

• Round 13 to 14

• Round 4 to 5

• Round 13 to 15

What is the total cost of four baseball tickets if each costs $17?

• $34

• $51

• $68

• $85

How do you estimate the cost of four tickets priced at $17 each?

• Round 17 to 15

• Round 17 to 20

• Round 17 to 25

• Round 17 to 10

If four toy cars fit in a box, how many boxes are needed for 13 cars?

• 2 boxes

• 3 boxes

• 4 boxes

• 5 boxes

What is the remainder when 13 cars are divided into groups of 4?

• 4 cars

• 1 car

• 2 cars

• 3 cars

How do you ensure all cars have a box when estimating?

• Round down to the nearest multiple of 4

• Round up to the nearest multiple of 4

• Ignore the remainder

• Use the exact number of cars

What is the purpose of using real objects in solving word problems?

• To increase the difficulty

• To visualize and simplify the problem

• To make the problem more complex

• To avoid calculations
