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, adding near doubles is a concept that I learned along with my oldest when she went through second grade. We made this near doubles activity to help with second grade math concepts, using a fun spider craft. The OT in me loves that it works on quite a few fine motor skills and scissor skills too!

## Adding Doubles and Near Doubles ## What is 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.

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. 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 white 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.
