Odd or Even?

In math, we have been working hard on making a model and using math vocabulary to explain our thinking.  

Today we were learning about odd and even numbers.  We created models on the double 10's frames to see if a number could be divided into equal groups.  Then we used an ap called Show Me to take a picture of our model and record an equation that helped us prove and explain whether the number was even or odd.

The math vocabulary words that we used were:
     odd
     even
     equal groups

Can you use the vocabulary words and the picture below to explain why 17 is odd?
