double-digit math {without regrouping}

Now that my students have somewhat "mastered" the art of addition and subtraction {mentally}, we have moved onto double-digits {without regrouping}! Wahoo! My second graders think they are so big now.

When I explained how easy it was to do double-digit addition/subtraction, they got so excited. 
I could tell that they understood what I was saying and that they were feeling really smart.

To go along with what I have already taught my students, I will be putting these anchor charts up in our classroom to help reinforce the correct way to do 2-digit math. I can't wait to show these to them tomorrow!
{A good reminder for your students: You should start on the RIGHT if you want to get it RIGHT!

The darling Amy over at Step Into 2nd Grade With Mrs. Lemons has some really great printables here and here. I have been using her worksheets in my classroom this week and my students really like them!

I also found some great worksheets here and here.

How do you teach double-digit addition/subtraction?

  3. Ug, I sure hope you post regrouping ones sometime... my 4th graders are TERRIBLE at subtracting through 1,000's.. Probably too much for second graders?? Oh well, tooo cute!!

  4. I liek to teach number bonds, i.e. 56 + 27= 6+7 and 50+20. the kids solve to have 13 and 70, which equals 83. SOOOO much easier than the traditional algorithim I was taught in school! And eventually it gets to be all mental math, too!

  6. love it!!! We've done addition and just started subtraction today. We use pretzel rods and m&m's to make our 10's column and 1's column (mainly just because I don't have base 10 blocks... ha!)

  7. I am wondering if you would be willing to make the chart again for me so that on the tens side it would say 30-10= 20 in the little box on the left (because really it is!)
    Thanks!

  16. I have seen this anchor chart over and over on various boards I follow on Pinterest. We start this skill this week and I'll be using it with the kiddos. I made a freebie worksheet to go with it. I embeded the pin on my blog post so people know where to get the original anchor charts.

    Thanks so much.
