Today we went a little deeper into our understanding of turnaround facts in math. We started out with a review of what we learned yesterday. I used clothes hangers each with a number 6, 7, 8, 9 and 10. On one side of the number I placed one color of pins and the other side another color of pins in combinations to equal the number on the hanger. We read the number sentence left to right, wrote it on our dry erase boards and then as we flipped the hanger around, the kids were able to see, say and write the turnaround fact.
It was fun to hear and see the "lightbulbs" go on in their heads as they smiled and said "OOOHHH!". We talked about what stayed the same in each number sentence as well as what changed.
Then we talked with our neighbor about what we thought the term turnaround fact meant.
Once I felt comfortable with their understanding of turnaround facts, I introduced two activities that they would do independently.
Each child received a baggie with domino cards and number sentences. We first laid out all the domino cards and then set out to match the fact and the corresponding turnaround fact to each domino. The kids did great!! As this student, continued to sort her cards, she realized a couple of mistakes and was able to easily correct herself without any support!
The kiddos next task was to use the containers of dominoes that I set out at their tables to do more turnaround facts. This time, they chose a domino, drew it in their math journal, and then wrote the fact with the answer as well as the turnaround fact. They really were engaged and independently discovered that doubles do not have turnaround facts!
At the end of our math lesson today we watched a Youtube video about Turnaround facts...I'm not quite sure how I feel about it...kids were intrigued...you will have to check it out yourselves and make your own opinions!
Now...on to Friday-Have a great weekend everyone!
Do you have a printable of the dominoes and equation cards?
