100 Square Muddle Maths focus: This game will help learners to become familiar with the layout and patterns of numbers in a 100 square. A game for two or t hree players You will need: • A ‘100 Square Muddle’ board (page xx). • A different coloured counter or alternative for each player. • A number or spot dice. How to play 1. In order to help learners work out where to move their counter to, it may be useful to explore which numbers have been swapped and how they link to each other before starting the game. 2. Players put their coloured counter on start (1) then take it in turns to roll the dice and move their counter along the 100 square by the number of spaces shown on the dice. Players need to take care to progress along the square, and at the end of each row, they must move their counter on to the beginning of the next row. 3. Some of the numbers have been swapped. If a player lands on a swapped number (for example 60 in the rst row) they must move their counter to where the correct number is (in this case, 6). Sometimes this will take them closer to the Finish (100) and sometimes this will take them back towards the start. The winner is the rst player to land on 100.
4. For an extension activity, give learners a 100 square and a blank 100 square to enable them to make up their own 100 Square Muddle. They could play the game with a partner or challenge them to spot and colour the swaps.

100 square games Maths focus: These games help learners to focus on the number pattern produced when adding or subtracting 10 repeatedly.
Game 2: Taking Taking away 10
A game for two or t hree players
1. As Game 1, but players start by putting their col oured counter on any number in the last row of the 100 square, 91 to 100. Players then take it in turns to roll the dice. If the number rolled is odd (1, 3 or 5) the player’s counter stays where it is. If the number rolled is even (2, 4 or 6) the player moves their counter one row up the 100 square, taking away (subtracting) ten. For example if the player starts on 93: 93�10 � 83 83�10 � 73 73�10 � 63 and so on. 2. The winner winne r is the rst player to reach the rst row of the 100 square.
You will need: • A ‘100 Square’ board. • A different coloured counter or alternative for each player. • A number or spot dice.
Game 1: Adding 10 How to play 1. Players put their coloured counter on any single–digi t number. Players then take it in turns to roll the dice. If the number rolled is odd (1, 3 or 5) the player’s counter stays where it is. If the number rolled is even (2, 4 or 6) the player moves their counter one row down the 100 square, adding ten. 2. Players record their journey down the hundred square. For example if the player starts on 6: 6�10 �16 16�10 � 26 26�10 � 36 and so on. 3. The winner is the rst player to reach the bottom row row of the 100 square.

100 Target Target board Maths focus: These games will help learners to recall all the addition and subtraction facts for the pairs of multiples of 10 with a total of 100.
Game 2: Subtraction As Game 1, but the player says the subtraction fact. For example, if a 60 card is turned over, the player says “100�60 � 40” and places the card on their 40.
Game 1: Addition A game for two players
Maths focus: This game will help learners to practise rounding numbers to the nearest 10.
You will need: • A ‘100 Target’ Target’ board for each pl ayer. • Two sets of 0 to 100 multiples of 10 cards. If the cards from the Multiples of 10 sheet are used, only one 50 from each set is needed. How to play
Players take a ‘100 Target’ board each. They shufe the two sets of cards and place the pile of cards face down between them. The players take it in turns to turn the top card over and place it on the other number of the pair to make 100, saying the addition fact. For example, if a 60 card is turned over, the player says “60+40 = 100” and places the card on their 40. If the number is already covered by a card, the card is returned face down to the bottom of the pile. The winner is the rst player to match all the numbers on their target board.
Game 3: Rounding
A game for two players You will need: • A ‘100 Target’ Target’ board for e ach playe r. • A set of 0 to 100 cards, with the tens numbers and zero removed. How to play
Players take a ‘100 Target’ board each. They shufe the cards and place the pile of cards face down between them. The players take it in turns to turn the top card over. They round the number to the nearest 10 and place the card on that number. The winner is the rst player to cover all the numbers on their target board

Playing with 20 Maths focus: These games help learners to practise number pairs from 11 to 20 or subtraction pairs from 11 to 20. By blocking off an appropriate number of squares on each side of the ‘Playing with 20’ game board, number pairs or subtraction pairs for any number between 10 and 20 can be explored. Game 1: 20 Pairs A game for two players You will need: • 20 counters (or alternative), cubes or other counting equipment small enough to t one in e ach square of the ‘Playing with 20’ board. • A 1 to 6 dice. How to play 1. Place the 20 counters in the grey oval. Each player uses one pair of 10 frames as their base board. Players take turns to roll a dice and take that number of counters from the grey oval. They then place one in each square on their base board. If there are not enough counters in the grey oval to match the dice number, players may take counters from the other player’s frames. The winner is the rst player to have all 20 counters, lling both their ten frames. 2. Each time there are no counters left in the central oval, players can see a pair of numbers with a total of 20. They can record these as addition facts, either in the oval or on a separate piece of paper. For example, if there are 14 counters on the rst pair of ten frames and 6 on the second pair of ten frames, then
14+6 = 20. As the dice is rolled and counters moved, a new pair of numbers with a total of 20 will be revealed and can be recorded in the same way. Game 2: Playing with 11 to 19 A game for two players You will need: • 11 to 19 counters (or alternative), cubes or other counting equipment small enough to t one in each square. The number of counters needed depends on the number being explored. Cross out the 20 in the title and write the number the learners are exploring. • A 1 to 6 dice or spinner. How to play 1. Each player needs to colour in one or more squares on the second of their ten frames, starting from the bottom, in twos. So if the game is ‘18 Pairs’, they must colour in the bottom two squares on the second ten frame, leaving a ten frame and an eight frame as their base board. The coloured spaces cannot be used in the game. 2. Place the counters in the grey oval. Each player uses one pair of partly coloured ten frames as their base board. Players take turns to roll a dice and take that number of counters from the grey oval. They then place one in each square on their base board. If there are not enough counters in the grey oval to match the dice number, players may take counters from the other player’s frames. The winner is the rst player to ll both their frames.
3. When there are no counters left in the central oval, players can see a pair of numbers with a total of 18 (or whatever number they are working with). They can record these as addition facts, either in the oval or on a separate piece of paper. For example if there are 12 counters on the rst pair of ten frames and 6 on the second pair of ten frames, then 12+6 = 18. As the dice is rolled and counters moved, a new pair of numbers with a total of 18 will be revealed and can be recorded in the same way. Game 3: 20 Take away A gam e for two players You will need: • 20 counters (or alternative), cubes or other counting equipment for each player. They must be small enough to t one in each square. It is better if each pl player ayer has a different colour or different objects. • A 1 to 6 dice or spinner. How to play 1. Each player starts with 20 items on their two ten frames. They take it in turns to roll a dice or spin a spinner and remove that number of counters from their frame, placing them on the grey oval. Players can only remove the number of counters which is indicated by the number on the dice. For example, if they throw a 5, but have only four counters, they miss a turn. The rst player to remove all 20 of their counters is the winner. 2. As players remove counters from their ten frames, they record the subtraction they have carried out. So if a player starts by rolling a 3 and removes three counters, they can record this as 20�3 � 17. If their next roll of the dice is a 5, they remove ve more counters. Their ten frames now show 20–8 (as they have taken away 8 counters altogether) � 12 as they have 12 counters left on their ten frames.
Game 4:11 to 19 Take away A game for two players players You will need: •11 to 19 counters (or alternative), cubes or other counting equipment small enough to t one in each square. The number of counters needed depends on the number being explored. It is better if each player has a different colour or different objects. Cross out the 20 in the title and write the number the players are working with. • A 1 to 6 dice or spinner. How to play 1. Each player needs to colour in one or more squares on the second of their ten frames. So if they are going to explore subtraction pairs for 18, they must colour in the bottom two squares on the second ten frame, leaving a ten frame and an eight frame as their base board. The coloured spaces cannot be used in the game. 2. Play as for 20 Take Take away but with the appropriate number o f counters. 3. As players remove counters from their ten frames, they record the subtraction they have carried out. So if the game is ‘18 Take away’ and a player starts by rolling a 3 and removes three counters, they can record this as 18 �3 � 15. If their next roll of the dice is a 5, they remove ve more counters. Their ten frames now show 18�8 (as they have taken away eight counters altogether) � 10 as they have ten counters left on their ten frame.

Adding game Maths focus: This game generates numbers for players to add together so that they can practise different addition strategies. A game for two players You will need: • An ‘Adding ‘Adding game’ board. • A counter (or alternative) for each player. • A 1 to 6 dice or spinner. How to play 1. Players place their counter on Start. They take it in turns to roll the dice (or to spin the spinner) and move their counter that number of spaces. Players collect the numbers they land on by recording them on a piece of paper or whiteboard. When they reach Finish, they total their numbers any way they choose. They then swap lists and check each other’s calculation by adding the numbers in a different way. The winner is the player with the greatest total.

X grid Maths focus: This game will help learners to focus on what multiplication is, by focusing on multiplying two dice numbers together. A game for two players You will need: • An ‘X grid’ board. • A 1 to 6 dice. • A dice with faces showing 2, 5, 10, 2, 5, 10. • Counters (or alternative) or cubes in two different different colours. How to play 1. Players take it in turns to roll both dice. The 1 to 6 tells them ‘how many times’ and the 2, 5, 10 tells them the number they are multiplying. So a 3 and a 10 means 3 times 10. 2. Players cover the number (found by multiplying the two numbers together) on the ‘X grid’ board with a counter or cube. If the number is already covered, they miss that turn. The winner is the rst player to get three counters in a row – horizontally, vertically or diagonally.

Playing with 100 Maths focus: These games help learners to practise nding pairs of multiples of 10 with a total of 100 and record the related addition and subtraction facts. Game 1: Playing with 100 A game for two players You will need: • A ‘Playing with 100’ board. • Ten counters (or alternative), all with 10 written on the front and back (the colour of the counter is not important, but it is better if they are all the same colour). • A 1 to 6 dice. How to play 1. Place the ten counters in the grey oval. Players might like to count in tens as they place each counter in the oval, to remind themselves that each counter is worth 10. Each player uses one 10 frame as their base board. Players take turns to roll a dice and take that number of counters from the grey oval and place one in each square on their base board. If there are not enough counters in the grey oval to match the dice number, players may take counters from the other player’s frame. The winner is the rst player to ll their ten frame. 2. When there are no counters left in the central oval, players can see pairs of multiples of 10 with a total of 100. They can record these as addition facts, either in the oval or on a separate piece of paper. For example if there are four counters on one player’s ten frame and six on the other, then 40 (four counters each with 10 written on them) �60 (six counters each with 10
written on them) = 100 (ten counters each with 10 written on them). As the dice is rolled and counters moved, a new pair of multiples of 10 with a total of 100 will be revealed and can be recorded in the same way. Game 2: 10 0 Take Take away A game for two players You will need: • A ‘Playing with 100’ board. • 20 counters (or alternative), all with 10 written on the front and back (the colour of the counter is not important, but it is better if each player has a different colour). • A 1 to 6 dice. How to play 1. Each player starts with ten counters on their ten frame. They take it in turns to roll a dice and remove that number of counters from their frame, placing them on the grey oval. Players can only remove the amount shown on the dice. For example, if players roll a 5 and there are only four counters remaining on their ten frame, they must miss that turn because they cannot remove the number shown on the dice. The rst player to remove all ten of their counters is the winner. 2. As players remove counters from their ten frame, they record the subtraction they have carried out. So if a player rolls a 3 and removes 3 (worth 30) counters, they can record this as 100�30 � 70. If their next roll of the dice is a 5, they remove ve more counters (worth 50), their ten frame is now showing 100�80 (as they have taken away eight counters, worth 80) � 20 (as they have two counters, worth 20, left on their ten frame.
Game 3: Playing with 100 add and subtract A game for two players You will need: • A ‘Playing with 100’ board. • Ten counters (or alternative), all with 10 written on the front and back (the colour of the counter is not important, but it is better if they are all the same colour). • A 1 to 6 dice. How to play 1. Place the ten counters in the grey oval. Players might like to count in tens as they place each counter in the oval, to remind themselves that each counter is worth 10. Each player uses one ten frame as their base board. Players take turns to roll a dice and take that number of counters from the grey oval and place one in each square on their base board. If there are not enough counters in the grey oval to match the dice number, players may take counters from the other player’s frame. The winner is the rst player to ll their ten frame. 2. When there are no counters left in the central oval, players can see pairs of multiples of 10 with a total of 100. They can record the addition and subtraction facts for what they can see, either in the oval or on a separate piece of paper. For example if there are four counters on the rst ten frame and six on the second ten frame, then they can see that: 40�60 � 100, and: 60�40 � 100 by looking at the frames in a different order.
They can also see that: 100�40 � 60, and: 100�60 � 40 by remembering that they started started with 100; one player has 40 of them and the other 60: 3. 40 (four counters each with 10 written on them) � 60 (six counters each with 10 written on them) � 100 (ten counters each with 10 written on them). As the dice is rolled and counters moved, a new pair of multiples of 10 with a total of 100 will be revealed and can be recorded in the same way.
