Adding Integers with Integer Tiles Explained

The video tutorial explains how to use tiles to model and solve addition and subtraction problems with integers. It introduces the concept of positive and negative tiles, demonstrates how to create zero pairs to simplify calculations, and provides examples of solving problems with and without zero pairs.

What is the first step in using tiles to add and subtract integers?

• Understanding zero pairs

• Modeling the problem with tiles

• Adding positive tiles

• Subtracting negative tiles

In the problem 10 + -7, what do the 10 positive tiles represent?

• Starting with 10 negative tiles

• Adding 10 positive tiles

• Adding 10 negative tiles

• Starting with 10 positive tiles

What does adding -6 tiles to 8 tiles represent?

• Adding 6 positive tiles to 8 negative tiles

• Adding 6 positive tiles to 8 positive tiles

• Starting with 8 positive tiles and adding 6 negative tiles

• Starting with 8 negative tiles and adding 6 negative tiles

What are positive 6 and negative 6 considered as?

• Opposites

• Identical pairs

• Equal pairs

• Zero pairs

What happens when you combine opposites?

• They add up to a negative number

• They cancel each other out to make zero

• They add up to a positive number

• They double the value

What is the result of combining a positive tile and a negative tile?

• Zero

• A positive tile

• Two tiles

• A negative tile

In the problem -4 + 9, what is the first step?

• Starting with four negative tiles

• Adding nine positive tiles

• Starting with four positive tiles

• Adding nine negative tiles

What is the result of -4 + 9 after crossing out zero pairs?

• Positive five

• Negative five

• Zero

• Positive four

In the problem -10 + 7, what is the final answer after crossing out zero pairs?

• Negative three

• Zero

• Negative ten

• Positive three

In the problem -3 + 8, why are there no zero pairs?

• Because there are no positive tiles

• Because all tiles are positive

• Because there are no negative tiles

• Because all tiles are negative
