2.OA.2 Math Facts Activities

 House # Math

Fun idea from E is for Exploring.

This activity is from one of my favorite sites for real world math, Illuminations! Students create a three digit house number, using numerals 0 through 9. The three numbers they choose must add up to a certain sum. They can't repeat numbers in their combination or begin their combination with 0. For example, if their number has to equal 6, one combination might be 321. There are 14 combinations if the sum is 6. If the 3 addends must add up to 7, there are 18 combinations. Visit Illuminations for details and printables to go along with the activity.

Afterwards, incorporate measuring by having students create a "house that measures up" from Cathy Searcey. After kids make their "house plan," they head outside and draw a large version of their house using sidewalk chalk. (House dimensions: 6ft. x 6ft. frame, a 3ft. x 1ft. door, and two 1ft. x 1 ft. windows).

You could also explore geometry by having students design their very own clubhouse! Click here for details!

Magical Missing Addends

Now you see it, now you don't! Three hands on ways to explore missing addends!

Featured Above:

1. Paper Slider - Mrs. T.'s First Grade Class had fun figuring out the missing addend with a sliding bar! Click here for details, as well as for lots more awesome activities and printables!

2. Paper Peeker - Our Future is Bright created addition sentences with a mini flap for the missing addend. Visit her blog for a free printable!

3. Tell a friend to draw 2 cards and create an addition (or subtraction, multiplication, or division sentence) with a missing addend. Then, magically solve it right before their eyes!

Vowel and Consonant Addition

Great idea from the first grade parade.

 Student count the vowels & consonants in their friends’ names and record the results.  Then combine the two numbers to create a number sentence!  Students flip the numbers. Click on the link below the pic to download the recording sheet.

Subtraction Squares

Fun, problem solving game for kids to practice subtraction skills from Learn with Math Games! This activity can be adapted to any age group. Younger kids can work with numbers less than ten. Older kids could work with 3 or 4 digit numerals.
Kids choose 4 numbers (anything they'd like) to write on the vertices of the larger square. Then, they just subtract (corner to corner). They write the differences on the next largest square's corners (where it meets in between on the line) and so on...
The big surprise is their final square! Like magic, all of the corners are the exact same numeral! Inference: See if kids can predict what will be their mystifying number before solving all their squares! Visit Learn with Math for a free template!
