| Beskrivelse | This activity focuses on understanding numerals as representing objects or sets of objects. It addresses the distinction between using place value and not using place value. For example, in the image above, 1 and 2 are placed next to each other. This means that one puppy and two puppies are hiding. The total number of puppies hiding is three, not twelve. |
