I found an amazing book about it.
Number Sense Routines by Jessica Shumway

Have you ever tried to explain to a parent what number sense is? Shumway says "number sense is very complex and there are many layers to it. It is rooted within all strands of mathematics. Number sense facilitates problem solving, reasoning, and discussing mathematical ideas." She then 'unpacks' the term number sense for you which includes subitizing, magnitude, counting, on-to-one correspondence, cardinality, hierarchical inclusion, part/whole relationships, compensation, and unitizing.
Wow! Those are some big words with big meanings. If we are not sure what they are and we are teaching first grade, we need to do a little homework and get with the program. I know I need to and I'm spending my summer studying and trying figuring this all out.
What's great about this book is Shumway gives you valuable information about number sense. Then she goes on to give you the tools to plan effective strategies to facilitate numerical literacy with your students. It's for grade K-3 which helps you see where your students are coming from and where they are going. The routines are warm-ups- quick 5-10 minute experiences at the beginning of your math class. Shumways says, "the 'daily-ness'- the everyday interactions-with numbers, amounts, patterns, and relationships will build your students' number sense."
Some of the specific routines detailed in the book are: Quick Images, Ten-Frames, Rekenrek, Count Around the Circle, Choral Counting, Start and Stop Counting, Organic Number Line, Ten Wand, Ways to Make a Number, Today's Number, Mental Math, Calendar, Collecting Data Over Time, and Counting the Days in School.
Over the years, I've done many of these activities but Shumway goes into depth with thought provoking questions and activities that deepen understanding.
If you want a great book for your summer reading, I'd suggest this one. It would make a great grade level team book study.
Hope I haven't bored ya'll but I get excited when I find a great book.
I'd LOVE to hear your comments.
