Exploring Foldable Techniques for Adding Integers

The video tutorial teaches how to add integers with the same sign using integer chips and a number line. It explains the rule of keeping the sign and finding the sum for integers with the same sign. Examples are provided for both positive and negative integers using integer chips. The tutorial also demonstrates how to use a number line to add integers, emphasizing starting at zero and moving forward or backward based on the integer's sign.

What is the rule for adding integers with the same sign?

• Divide the numbers and keep the sign.

• Multiply the numbers and change the sign.

• Subtract the smaller number from the larger number.

• Add the numbers and keep the sign.

What is the sum of +2 and +5 using integer chips?

• +10

• +7

• +3

• +5

Why can't zero pairs be made with +2 and +5?

• Because the numbers are too large.

• Because there are no positives.

• Because there are no negatives.

• Because the numbers are too small.

What is the sum of -3 and -1 using integer chips?

• -4

• -2

• -1

• -3

Why can't zero pairs be made with -3 and -1?

• Because there are no negatives.

• Because there are no positives.

• Because the numbers are too small.

• Because the numbers are too large.

What is the sum of -1 and -6 using integer chips?

• -7

• -6

• -8

• -5

What is the sum of +1 and +7 using a number line?

• +8

• +6

• +7

• +9

What is the sum of -3 and -3 using a number line?

• -7

• -6

• -5

• -4

What is the sum of -5 and -4 using a number line?

• -10

• -9

• -8

• -7

When using a number line, where do you start?

• At the largest number.

• At the smallest number.

• At zero.

• At the middle of the number line.
