Domino Sequences

Stage: 1 Challenge Level: Challenge Level:1

David from Tithe Barn Primary School sent us some drawings of the dominoes which complete these sequences. Abigail and Rachel from Histon and Impington Infants School have explained the patterns for the last two:
1/4, 1/5
3/1, 2/0
4/3, 3/3
4/3, 5/2 You are counting backwards on the bottom and forwards on the top. You would need an extra domino set, because the same dominos are used twice.
3/0, 3/5 There are two patterns that bounce over each other:
0/5 1/5 2/5 3/5 and 1/0 2/0 3/0
Jeff from Kelly Elementary School in Carlsbad, California and Charlie and Jake from Moorfield Junior School also sent us correct solutions.
