Video transcript

we're told Lulu was packing for trip she put her clothes inside of her suitcase in two rows with five shirts in each row so I guess what they're drawing here is this is hers her open suitcase and each of these squares is a shirt and you can see there's one two three four five shirts in the first row and then another five shirts in the second row and then they asked us which expression or I guess we see expressions could we use to find the total number of shirts Lulu packed and so pause this video and think about which of these expressions could we use to find the total number of shirts and I'll give you a hint it could be more than one of these all right now let's work through this together so before I even look at these choices I can look up here and say okay I have five in that first row and then I have five in the second row so I have two groups of five so I could view this as 5 plus 5 total shirts and you can see that's this choice right over here now are there other ways to view this instead of viewing it as two groups of five what if we view it as five groups of two that's one group of two that's another group of two a third group of two a fourth group of two and a fifth group of two so you could view it as these two plus these two plus these two plus these two plus these two five groups of twos or you could say five twos which we have right over here we have five twos and we're adding them all together so I like this choice as well
