Fast forward a few hours to my guided reading group. As we sat down to begin, one of my little girls told me "You are my favorite and the best teacher ever!" Right as she finished her sentence another little boy in the group (who is one of those kids that is a 50 year-old man trapped inside a 6 year-old's body) looked at me very matter-of-factly and simply said "No offense Mrs. Zanchelli but I have had better." HAHA Oh my gosh, what do you do besides laugh?!? I mean I am glad he was honest; however, I felt like having a chat with him about keeping those kinds of thoughts to himself! :) So I laughed and then simply replied by saying "We all have our own opinions!!"

Number sense is a huge part of our first grade math curriculum. It feels as though we are constantly working on number sense and are continuously recycling back to similar concepts throughout our curriculum to help students gain a deeper understanding as we have moved to the common core standards. A few weeks ago we discussed doubles and this week we are working on some Doubles, Doubles Plus One, and Doubles Plus Two math facts. Many of my students know 5+5=10 but when I ask them 5+6= they quickly bring out their fingers. I have know problems with students using their fingers but am trying to help them realize that all they have to do is add ONE more to the double's sum instead of starting all over again from the first number. It's a process but I know we will get there!
I created this freebie Doubles and Doubles Plus One Task Cards to help my students practice. It is a simple set of 12 cards to help students realize if they know the sum of any double they can easily get to the sum of any doubles plus one problem.
