Teacher Notes

X

Use DPP item L to practice addition facts and the related subtraction facts for Group D.

1. 4 + 5 =  9                           9 − 5 =  4
   
    9 − 4 = 5                           5 + 4 = 9
2. 6 + 7 = 13                           13 − 7 = 6
   
   7 +  6 = 13                           13 − 6 = 7
3. 7 + 8 = 15                            8 + 7 = 15
   
   15 −  7 = 8                           15 − 8 = 7

Ongoing Assessment

Use DPP item L to assess students’ fluency with the addition facts with sums to ten in Group D [E10], strategies with the addition facts in Group D [E11], and the related subtraction facts [E12].
