Numbers 10-20 with QR Codes

Kindergarten iPad Activity

Va Math SOL K.2

The student, given a set containing 15 or fewer concrete objects, will

  • tell how many are in the set by counting the number of objects orally;
  • write the numeral to tell how many are in the set; and
  • select the corresponding numeral from a given set of numerals.

Directions for Teacher

  1. Using the Numbers 10-20 Resource below, cut out the QR codes and glue into a folder to create a folder game or glue on index cards. A folder cover is also available. Laminate for long term use. TIP: I have found it better to glue the QR codes far apart. It makes it easier on the students when scanning.
  2. Model how to scan QR codes using the i-nigma app. Open the app. Hover the iPad over one of the QR codes so the code is inside the red box. The iPad will blink when it has read the code. Tap the black "go online" button. Safari will open on the iPad revealing a picture/number.
  3. Model how to use the Doodle Buddy app. Tap the purple piece of chalk to get drawing tools, the eraser, and to change the size of the pen. Tap the stamp tool to get a wide variety of pictures and to choose the size. Tap the shapes tool to add shapes. Tap the Tt tool to add text. Tap the tic-tac-toe board to add a background including pictures from the camera roll. Demonstrate how to make the number that was scanned by adding stamp then write the number with the drawing tool. Tap the trash can to clear the board.
  4. Model how to multi-task between two apps. Tap the home button twice to reveal all open apps. Tap i-nigma to scan...two taps of the home button...tap Doodle Buddy to draw. Have students practice multi-tasking.
  5. Place the Numbers 10-20 folder game in a station and watch your students have fun.
