I think the 10x2 array doesn't belong because it is the only model that doesn't have 30 cubes.

I'm happy it's challenging! That means your brain is growing while you think about this one. There is no wrong answer. Take some time to look at the four images and YOU can decide which one you think is different than the others. You got this! :)

Remember Meabh - YOU can do hard things! Take a look at the cubes and find how 3 are alike and one is different. Give it another shot!

The one that does not belong is the one that has ten rows of two because all the other ones have an area of 30 and that one has an area of 20.

Great job, Drew. I love how clearly you explained your thinking.

The one that is in the middle does not belong because it has an area of 20 and all the others are 30. That is the one that doesn't belong.

I think that the 10 x 2 is the one that doesnt belong becuase the others have 30 and this one has 20

Where's the Math!?
