Monday
Can you see a pattern? 0+-__ = 10 1+ __ = 10 2+ __ = 10 3+ __ = 10 4+ __ = 10 5+__ = 10 6+ __= 10 7+ __ = 10 8+ __ =10 9+__ + 10 10+ __ = 10
Now try these 1 0+__ = 20 11+ __ = 20 12+ __ = 20 13+ __ = 20 14+ __ = 20 15+__ = 20 16+ __= 20 1 7+ __ = 20 18+ __ 20 1 9+__ + 20 20+ __ = 20
Tuesday
Can you see the pattern? 2 0+__ = 30 21+ __ = 30 22+ __ = 30 23+ __ = 30 24+ __ = 30 25+__ = 30 26+ __= 30 2 7+ __ = 30 28+ __ 30 29+__ + 30 30+ __ = 30
Wednesday
Can you see the pattern? 3 0+__ = 40 32+ __ = 40 34+ __ = 40 36+ __ = 40 38+ __ = 40 40+__ = 50 42+ __= 50 44+ __ = 50 46+ __ = 50 48+__ = 50 50+ __ = 60
Thursday
