Example Question #451 : Operations & Algebraic Thinking
Is there an even or an odd number of dots below?
Neither
Even
Both
Odd
Even
When trying to decide if we have an even or an odd number of items, we can put the items in pairs of two. If each item is in a pair, then we have an even number of items. If there is one item that isn't in a pair, then we have an odd number of items.
In this case, our dots are in pairs of two, so we have an even number of dots.
Example Question #452 : Operations & Algebraic Thinking
Is there an even or an odd number of dots below?
Both
Odd
Neither
Even
Even
When trying to decide if we have an even or an odd number of items, we can put the items in pairs of two. If each item is in a pair, then we have an even number of items. If there is one item that isn't in a pair, then we have an odd number of items.
In this case, our dots are in a pair of two, so we have an even number of dots.
Example Question #453 : Operations & Algebraic Thinking
Is there an even or an odd number of dots below?
Both
Odd
Neither
Even
Odd
When trying to decide if we have an even or an odd number of items, we can put the items in pairs of two. If each item is in a pair, then we have an even number of items. If there is one item that isn't in a pair, then we have an odd number of items.
In this case, we have one dot not in a pair, so we have an odd number of dots.
Example Question #454 : Operations & Algebraic Thinking

When trying to decide if we have an even or an odd number of items, we can put the items in pairs of two. If each item is in a pair, then we have an even number of items. If there is one item that isn't in a pair, then we have an odd number of items.
In this case, our dots are in pairs of two, so we have an even number of dots.
Example Question #455 : Operations & Algebraic Thinking
Is there an even or an odd number of dots below?
Odd
Both
Neither
Even
Odd
When trying to decide if we have an even or an odd number of items, we can put the items in pairs of two. If each item is in a pair, then we have an even number of items. If there is one item that isn't in a pair, then we have an odd number of items.
In this case, we have one dot so it's can't be in a pair, so we have an odd number of dots.
Example Question #456 : Operations & Algebraic Thinking

When trying to decide if we have an even or an odd number of items, we can put the items in pairs of two. If each item is in a pair, then we have an even number of items. If there is one item that isn't in a pair, then we have an odd number of items.
In this case, our dots are in pairs of two, so we have an even number of dots.
