Mathematic Groups: Addition and Subtraction #2

Working at Stage 5

57 – 25 = ?                 85 – 8 = ?                       32 + ? = 67                  39 + 28 = ?

Working at Early 6 and Stage 6

? + 26 = 87                 478 – 232 = ?                 129 + 75 = ?               137 + 48 = ?

? + 147 = 175            83 – ? = 44                     232 – 78 = ?                144 = 88 + ?

Working at Early 7 and Stage 7

4.2 + 3.14 = ?            23.22 – 22.63 = ?            5.34 – 2.9 = ?              0.8 + ? = 1.25

10.7 – ? = 9.79          0.885 + ? = 1.5              1.755 + ? = 2.2              0.76 + ? = 0.8
