### Resources for Adding and Subtracting (3.NBT.A.2, 4.NBT.B.4, 5.NBT.B.7)

Adding and subtracting is not just for primary kids. The Common Core State Standards ask third graders to add and subtract within 1000 (3.NBT.A.2), fourth graders to add and subtract whole numbers of all sizes (4.NBT.B.4), and fifth graders to add and subtract decimals (5.NBT.B.7). Today we'll explore engaging resources that meet these standards.

Fall has arrived in the northern hemisphere, so let's look at some seasonal products first:

• Kids will enjoy playing Fill It In Bingo, created by Jan Gervais, to practice addition and subtraction of 2- and 3-digit numbers. (Click here for a non-seasonal version.)

• For Halloween (or any time), adding and subtracting decimals will be more fun with this coloring activity, created by Briana Burke. When finished, a spider is displayed!

• A variety of fall-themed task cards are available in this bundle. Each set is also sold individually at the Teachers pay Teachers store of Carol's Garden.

Do you use interactive notebooks in your classroom? Creative Critters offers interactive notebook foldables for addition and subtraction, as well as Subtraction Math Game: Alien Invasion. For a comprehensive approach to addition, subtraction, multiplication, and division, take a look at Interactive Math Journal for Operations by Jane Feener. This 204-page resource includes achievement indicators, notes, foldables, QR activities, and exit cards for fourth and fifth grade learners.

Task cards are a favorite go-to for kids. Chili Math has created task cards for adding and subtracting whole numbers. (If you want a variety activities, click here for his bundle of 540 cards.) For fifth graders, why not try Add and Subtract Decimal Task Cards from Hello Learning or Adding and Subtracting Decimals to the Hundredths Place by MissKinBK?

If you're looking for a little action in your classroom, this is the one for you. Jill Powers brings new meaning to the term "board games" with her product, Magnet Races: Decimal Calculations, which includes addition, subtraction, multiplication, and division of decimals.

Practice makes perfect! Misty Miller has created motivational math riddles for for subtracting 2-digit and 3-digit numbers, as well as decimals. Oodles of additional addition and subtraction worksheets are available at Math-Aids.com and Math-Drills.com. To generate your own worksheets, go to SoftSchools.com or WorksheetWorks.com.

The availability of free and inexpensive math resources has really improved my teaching. If my class seems bored with a topic, I can find something engaging with the click of a finger. If one of my students needs more practice, I can hop on the Internet and choose from dozens of appropriate sheets (or even create my own!) I hope this blog helps you find resources that are just right for your classroom. Thanks for stopping by!
