Addtron introduces the strategy of doubling to add. From this introduction, students use concrete materials and pictorial representations to add doubles and near doubles.
These whole-class activities provide students with the opportunity to:
- listen to a story about doubling to add
- use materials to act out the story
- use the Teaching Tool to act out the story
- use concrete and pictorial materials to make and add doubles
- use the Teaching Tools to match double number facts with double displays
- use pictorial materials to sort and add doubles and near doubles1 BB Addtron
