Understanding Subtraction with Blocks

The video tutorial explains how to solve a math problem involving finding a missing number in the equation 6 = blank - 7. The instructor uses visual aids, such as drawing blocks, to represent the problem and guide the viewer through the process of solving it. By subtracting seven from a series of blocks and counting the remaining blocks, the missing number is determined to be 13. The tutorial concludes with a verification of the solution.

What is the initial equation presented in the problem?

• 7 = blank + 6

• 7 = blank - 6

• 6 = blank - 7

• 6 = blank + 7

What does the teacher do to understand how many blocks to start with?

• Draws a few blocks and adds seven

• Draws a few blocks and subtracts seven

• Draws exactly six blocks

• Draws exactly seven blocks

Why does the teacher draw extra blocks?

• To ensure there are enough blocks to subtract

• To make the picture look complete

• To show the final answer

• To confuse the students

How many blocks are left after subtracting seven?

• Five

• Eight

• Six

• Seven

What is the missing number in the equation?

• 15

• 13

• 12

• 14

What trick does the teacher use to verify the solution?

• Using a calculator

• Drawing more blocks

• Adding the blocks back

• Counting the blocks in the picture

What is the purpose of the blocks that are not marked?

• They are the final answer

• They are used to confuse the students

• They are extra blocks drawn to ensure enough for subtraction

• They are used to add to the total
