Sugar Aunts: Near Doubles Second Grade Addition Facts

Near Doubles Second Grade Addition Facts

Today's post in our second grade learning series is all about adding Doubles and adding Near Doubles.  You might be thinking, "Say What?" I have to admit, I am no teacher and do not have a teaching degree so when my second grader brings home homework assignments, sometimes I have to look over the worksheet and read it through with her as I figure out exactly what she's learned in school that day.  As I read through the worksheet with her, I talk it out so that she gets a mini-review too.  Someday she may read this blog post and say, "MOM! You didn't know what all of those worksheets were teaching me???!!" And that's ok with me.  Yep, math is not my cup of tea.  (And actually, tea is not my preferred cup anyway.  I'm a coffee girl.) Some of the reviewing is me realizing that my baby girl is learning SO much SO fast.  And the other part is the "Ummm, I do not recall learning this in second grade." Then, there's the added component of Common Core math.  Let's just say, we're plowing through this together. 

Adding Doubles and Near Doubles

What is adding Doubles in Second grade math?  Adding doubles is a math fact memorization technique.  It is easier for kids to remember that 2+2=4, 6+6=12, 7+7=14, 9+9=18, etc.  Doubles are the addends that are exactly the same.  These are addition facts that second graders need to know to add within 20.

What is Adding Near Doubles in Second grade math?  Near Doubles are those addends that are almost a double fact. So, 4+5 is very close to 4+4.  Students can easily recall that the double fact for 4+4=8 and by adding one more, they quickly know that 4+5=9.  These are math fact tools that can help second graders add within 20.

Hands-On Math for Second Grade: Adding Near Doubles

We created a hands-on math activity using the doubles and Near Doubles addition facts with a spider theme.  It's an easy and quick activity to set up, that will help second graders realize how to quickly figure out more addition facts quite easily.  This is a math skill appropriate for Common Core Standards CCSS 2.0A.1 and CCSS 2.0A.2.  You can see those Common Core standards here.

To make your Near Doubles Spider Activity

Cut out 8 strips of black construction paper.  Cut out a circle for the head. Glue googly eyes onto the spider's head.  Using a wite crayon, write out doubles facts on one side of the spider legs.  You'll need 2+2=_, 3+3=_, 4+4=_, 5+5=_, 6+6=_, 7+7=_, 8+8=_, and 9+9=_.  

On the other side of each spider leg paper strip, write with your white crayon: 2+3=_, 3+4=_, 4+5=_, 5+6=_, 6+7=_, 7+8=_, 8+9=_, and 9+8=_.  You can make multiple versions of these numbers, using the commutative property of addition

Glue the legs to the spider head so the Doubles are all on one side and the Near Doubles are all on the other side.  Kids can flip the legs over to see how closely the doubles are to the Near Doubles and how knowing the Doubles facts can quickly help them figure out the Near Double facts.

  1. This is brilliant, as always! I love how the plus one facts are on the other smart!

  2. I am with you - I had no idea what those near doubles were before second grade of my daughter! The art-math project is very clever!
