QR Code Activity Representing Numbers in Expanded Form

posted Sep 11, 2017, 12:17 PM by Patrick Johnson



Today students practised representing numbers in expanded form. Expanded form is where you break down a number into its place value. For example, the expanded form of 158 is 100 + 50 + 8.

Students went around the room writing down the expanded form of numbers that were posted on the walls. Afterwards, students checked their answer by scanning the QR Code with an iPad. Students also could watch a video about expanded form by scanning one of the posted QR Code video links.
