Lucky locks
Children can work in pairs. They each need a copy of the Lucky locks activity sheet. Children fill in the gaps to make a number sequence and write the rule in words. The last four locks are blank. Two require children to invent sequences that fit certain constraints and the last two are empty for children to make up puzzles of their own for friends.

Fireball Race
A game for 1 - 4 players. Each player needs a copy of the Fireball Race activity sheet.

Place a set of digit cards (0 - 9) face down on the table. The first player turns over the top card so that all players can see it. All the players then have to find this number in the circles at the end of the flames. This number is the sequence number. It is the difference between the numbers in that sequence (on that flame). Players race to fill in the missing numbers in the flame. The first player to complete the sequence correctly shouts "Fireball!" and wins the blank mini fireball in the centre. The winner colours it in on their sheet or writes their initials in it. The next player then turns over another digit card and play continues until all the cards have run out. The winner is the player with the most fireballs.

Extension idea: children can design their own fireball races, with their own number sequences
