Mind and Fingers Addition Technique

In this video tutorial, the teacher introduces a mental math technique for adding numbers using the mind and fingers. The method involves placing the larger number in the mind and counting the smaller number on fingers. Several examples are demonstrated, including adding 5 and 3, 5 and 6, 13 and 6, and 8 and 23. The video concludes with a discussion on handling larger numbers and a promise to cover more techniques in future lessons.

What is the primary method taught in this lesson for adding numbers?

• Using an abacus

• Writing on paper

• Using mind and fingers

• Using a calculator

In the first example, what is the first step when adding 5 and 3?

• Put 3 in your mind

• Put 5 in your mind

• Raise 5 fingers

• Raise 3 fingers

After putting the larger number in your mind, what should you do next?

• Write the numbers down

• Raise fingers equal to the smaller number

• Subtract the smaller number

• Start counting from zero

In the second example, what is the sum of 5 and 6?

• 13

• 12

• 10

• 11

What is the first step in the mind and fingers technique?

• Put the smaller number in your mind

• Count backwards

• Put the larger number in your mind

• Raise all fingers

In the third example, what is the result of adding 13 and 6?

• 20

• 21

• 19

• 18

When adding 13 and 6, what number do you start counting from?

• 12

• 13

• 15

• 14

In the final example, what is the sum of 8 and 23?

• 33

• 31

• 30

• 32

What should you do if the smaller number is greater than 10?

• Use a calculator

• Use other techniques

• Guess the answer

• Skip the problem

What is the limitation of the mind and fingers technique discussed in the video?

• It requires more than 10 fingers for larger numbers

• It is not accurate

• It only works for numbers less than 10

• It is too slow
