Using Skip-Counting to Solve Missing Number Puzzles

This video tutorial explores the concept of skip-counting and its connection to repeated addition and subtraction. It explains how skip-counting creates number patterns, both increasing and decreasing, and demonstrates the relationship between addition and subtraction. The tutorial also covers how to identify changes in number patterns and solve for missing numbers using addition. By understanding these concepts, students can better grasp the interconnectedness of mathematical operations and improve their problem-solving skills.

What is the relationship between skip-counting forward and addition?

• Skip-counting forward is a form of division.

• Skip-counting forward involves subtraction.

• Skip-counting forward is the same as repeated addition.

• Skip-counting forward is unrelated to addition.

How can you identify the amount added in an increasing pattern?

• By counting the number of steps.

• By observing the change in the tens place.

• By checking the hundreds place.

• By looking at the units place.

What is the result of adding 5 to 355 in a skip-counting pattern?

• 365

• 370

• 360

• 350

What strategy can be used to solve skip-counting puzzles with missing numbers?

• Using repeated subtraction.

• Using division.

• Using repeated addition.

• Using multiplication.

How can addition be used to solve decreasing patterns?

• By switching directions and adding.

• By ignoring the pattern direction.

• By using multiplication instead.

• By subtracting larger numbers.

What indicates a pattern is increasing by hundreds?

• Change in the thousands place.

• Change in the units place.

• Change in the tens place.

• Change in the hundreds place.

If a pattern decreases by 10, what is the next number after 494?

• 474

• 484

• 504

• 514
