Devilishly Difficult Division!!

We started to talk about division today. We discussed that division is basically just sharing things. We can share things in a specific number of groups. For example, I have 16 candies and I want to share them amongst 4 friends (4 groups really). So, 16 candies in 4 groups means that each friend gets 4 candies. I can also share things when I don't really know the number of groups, I just know how many of something I want each group to get. For example, I have 20 candies now and I want to make sure that there are 2 candies in each group. I take my 16 candies and make 8 groups of 2 candies. The division sentence for this example would be 16 divided by 2 equals 8 groups. It's a subtle difference but one that students need to understand. I have included some videos below to remind the students. The first video is simpler and has a catchy song. The second video is more exact in it's presentation and shows the difference between the two examples I discuss above.
