SilverStripe get first children in a row

I have got multiple children which I display in a grid. 4 children fits in a row. Now I want to give every first and last children in a row an extra class to specify more styles. I tried: 

<% if FirstInRow %>
    <div class="gridContent firstInRow"></div>
<% else %>
    <div class="gridContent"></div>
<% end_if %>

That's the function:

function FirstInRow(){
    return ($this->Pos(1) % 4 == 1) ? true : false;
}

Modulus works better when you could starting from 0. Try this instead:

function FirstInRow(){
    return ($this->Pos(0) % 4 == 0);
}

Note that I removed the redunandant ternay operator as well; you can leave that in if it makes the code clearer to you.

You have the Modulus and MultipleOf controls available to you in the template.

$Modulus(value, offset) // returns an int
$MultipleOf(factor, offset) // returns a boolean.
