Today, we learned about adding integers using integer tiles. Remember that when we are adding, we take the first number and use integer tiles to model it. We take the second number and put it underneath the first one. If all of the colours are the same, simply count the number of tiles. If the colours are different, cross off any zero pairs and add up the tiles that are left. I have also included the marking key, just in case you are struggling., which is homework for Thursday.
