Use this step-by-step graphic organizer to scaffold your students’ thinking as they practice their doubles facts and the “doubles plus one” addition strategy!
Use any manipulatives necessary to supplement students’ drawings. All students should draw and/or write numerals to show their work. The first page has the most scaffolding and each subsequent page provides less support than the one before it.
Page 2: Has the most supports; bring down the 5, break up the 6 into 5 and 1.
Page 3: Students need to identify the doubles fact independently.
Page 4: Students need to identify the three addends independently.
Page 5: Students need to identify the two addends and break them down into three addends independently.
Page 6: Same as page 5, but addends are reversed (doubles fact is on left); must generalize the strategy and access knowledge of the commutative property to solve.
