## Counting with Digit Dog

Digit Dog and Calculating Cat have been practising their counting. Play their game by downloading it here.

If you want more ideas like this then book onto Mathematics and Numeracy in PS1 (Nursery and Reception) on October 13th 2021.

You need one counter and a dice (a dice with numbers 1, 2 and 3 is ideal but you can play with an ordinary 1 – 6 dice)

The game is for 2 players – one will be Digit Dog and the other will be Calculating Cat.

Put the counter on Start. Both players move the same counter BUT Digit Dog moves towards the bone and Calculating Cat moves towards the fish. Take turns to throw the dice and see who gets their food first. There will be a lot of moving back and fro.

When children throw the dice ask them to say how many spots there are without counting in ones – this is called subitising.

If you enjoyed the game why not try the Incey Wincey Spider game from www.nrich.org

## Reasoning with the Bottle Top Bugs

### Collect the bugs

You need:

A set of bottle top bugs  (0 – 12)

A set of leaves to put the bugs on (optional)

2 dice

Set out the leaves with one bug on each leaf.  Take turns to roll both dice and use either addition or subtraction to capture a bug. For example, if you throw a 5 and a 3 you can either add the numbers together, 5 + 3 = 8, and capture the 8 bug, or you can subtract the numbers, 5 – 3 = 2, and capture the 2 bug.

Explain your reasoning like Digit Dog.

When all the bugs have been captured, the player who has most bugs is the winner.

Which bugs are easiest to capture? Why do you think that?

Which bugs are more difficult to capture?

## Counting games

Digit Dog and Calculating Cat have been practising their counting skills by playing the Incey Wincey Spider  (Nursery and Reception) game (Year 1 and 2) from www.nrich.org

Digit Dog and Calculating Cat enjoyed the game so much that they made their own version of the game.

The game is for two players – one is Digit Dog, the other Calculating Cat.

You need:  One dice, one counter.

Digit Dog wants to get to the bone, Calculating Cat wants to get to the fish.

Put the counter on start.

Take turns to throw the dice and move the counter. Both players move the same counter – Digit Dog moves the counter towards the bone, Calculating Cat moves it towards the fish.

The winner is the one who gets to the food first.

Variations

Use two dice – throw the two dice and choose which dice you want to use.

Use two dice – add the numbers on the dice and use the total for your move.

Use two dice – find the difference between the numbers on the two dice and use the difference for your move.

## Who has more?

You need:

A set of Bottle Top Bugs

A feely bag / box or cloth

Put your bottle top bugs in a feely bag or a box or under a cloth. Each player takes one bug out, puts it in front of them and says how many spots there are. The player with more spots captures both bugs.

Keep playing until all the bugs have been used. The winner is the player who has  captured most bugs.

Who has more spots? How many more?

Say:

I have ……. spots. I have ……. more spots than my friend.

Make sure that learners also practice using the word fewer.

Who has fewer spots? How many fewer?

I have …….. spots. I have …….. fewer spots than my friend.

Practise subitising (saying how many spots there are without counting in ones).

When you turn over a bug, say how many spots there are without counting in ones. How do you know how many spots there are? Calculating Cat knows she has 11 spots because she saw two groups of 5 plus 1.

Vary the game

Change the rules so that the player with fewer spots wins.

Players take two bugs and add the number of spots together. They then compare their totals. The player with the greater total captures all four bugs.

Players take two bugs and find the difference. They then compare their differences. The player with the greater / smaller difference captures the four bugs.

## Go Fish 10

You play Go Fish 10 in the same way as Go Fish but the aim of the game is to make pairs that add up to 10.

Print Digit Dog’s cards here. You need 4 sets for 2 -3 players.

To play:

Deal each player 7 cards and spread out the remaining cards face down on the table. The aim of the game is to find pairs of cards that add up to 10.

Each player takes a turn. During a turn the player:

1. Looks at the cards in their hand, if they have any pairs that add up to 10, they put them in front of them, face up.
2. They then ask another player if they have a particular card so that they can make another pair. For example, player 1 might have a 4 in their hand and so ask aplayer 2 “do you have a 6?” – the card they need to make a pair that adds to 10. If player 2 has a 6 card, then they must give it to player 1. If they don’t have a 6 card, they say “go fish” and player 1 takes a card from the pool of cards on the table.
3. If the player gets the card they asked for, either from the pool or from the other player, then they put their pair of cards in front of them, face up.

The game ends when one player runs out of cards or there are no more cards in the pool. The winner is the player with most pairs in front of them.

What if………

………….you played the game by making pairs of cards with a difference of 1?

## Play Go Fish

How to play Go Fish

For 2 – 3 players you need to print 4 sets of Digit Dog’s cards, onto card. The cards have numerals along with ten-frames.

The game can also be played with digit cards 0 – 10 or 0 – 20, or  a pack of playing cards.

To play:

Deal each player 7 cards and spread out the remaining cards face down on the table. The aim of the game is to find pairs of cards.

Each player takes a turn. During a turn the player:

1. Looks at the cards in their hand, if they have any pairs, they put them in front of them, face up.
2. They then ask another player if they have a particular card so that they can make another pair. For example, player 1 might ask player 2 “do you have a 5?” If player 2 has a 5 card, then they must give it to player 1. If they don’t have a 5 card, they say “go fish” and player 1 takes a card from the pool of cards on the table.
3. If the player gets the card they asked for, either from the pool or from the other player, then they put their pair of cards in front of them, face up.

The game ends when one player runs out of cards or there are no more cards in the pool. The winner is the player with most pairs in front of them.

You need:

A set of counters for each player. One colour for each player. You can download Digit Dog counters here – print on card and cut out or print on paper and stick them on milk bottle tops.

A dice.

To play:

Take turns to throw a dice.

Double the number you throw, find the answer on the board and put your counter on it.

The winner is the first player to get three counters in a row.

Variation

Use a set of digit cards 1 – 19 and this board. Take turns to turn over a card, double the number and cover the answer on the board.

Digit Dog and Calculating Cat are playing Pass the Peas Please, a game they found on www.nrich.org

A game for 2 or more players

You need:

2 dried peas (or beans or counters or sweets).

A plastic cup.

A piece of paper and pencil for each player.

To play:

Each player begins by writing 50 on their piece of paper.

Player 1 places two dried peas into the plastic cup and tosses them onto the game board.

They add the two numbers the peas land on and then take the total away from 50 and write the answer on their score sheet.

The next player takes a turn.

In the following turns, the players take the sum of the numbers away from the new remaining number.

The first player to reach zero wins.

Variations

Start with 0 on your score card and keep a running total of scores. The winner is the first to reach 50.

Use one pea instead of 2 and either subtract the number the pea lands on from 50 or keep a running total.

Use 3 peas to play the game.

Each player takes a turn to throw two peas and add the numbers. The player with the highest total wins that round. Play 10 rounds.

Each player takes a turn to throw two peas and add the numbers. The player with the lowest total wins that round. Play 10 rounds.

Each player takes a turn to throw two peas and finds the difference between the numbers. The player with the highest difference wins that round. Play 10 rounds.

Make your own boards. Choose the numbers you put on the board.

## Playing with cards 5

Any number of players or teams of 2.

You need:

A pack of playing cards arranged in a 13 x 4 array, face down. Ace = 1, picture cards = 10.

To play:

Player 1 turns over 2 cards and adds the values. Player 1 then turns over another two cards and adds the values. If the totals match, player 1 keeps the 4 cards and has another turn. If they do not match, the cards are turned face down again and it is player 2’s turn.

The game continues until no more matches can be made.

Can you remember where cards are? How will this help you? Watch carefully when other players are turning over cards.

Variations

1. Play the same game but subtract the pairs of cards. If the answers match, keep the cards and have another turn. If they don’t, turn them face down again.
2. On each turn, turn over two cards. If the numbers match, keep the cards and have another turn. If they don’t match turn the cards face down again.
3. On each turn, turn over two cards. If the numbers and colours match, keep the cards and have another turn. If they don’t match turn the cards face down again.
4. On each turn, turn over two cards. If both numbers are odd or both even, keep the cards and have another turn. If they don’t match turn the cards back face down.
5. Make up your own rules!

## Playing with cards 4

2 – 5 players

You need:

Digit cards 1 – 10 (a set for each player) or playing cards with the picture cards removed.

To play:

Shuffle the cards and place in the centre.

Each player takes two cards from the pile, adds the cards together and tells everyone the total.

If the total is odd, the player keeps the cards. If the total is even, the cards are returned to the centre pile.

Play ten rounds or until there are no cards left.

The winner is the player with most cards.

Variations

• Leave the picture cards in and give them a value e.g. J = 11, Q = 12, K =13
• Deal 3 cards to each person.
• Keep adding the totals of the cards you keep. First player to reach a total of 50 wins.

## Largest number

2 – 4 players

You need:

Digit cards 1 – 9  (one set per player, shuffled) or a pack of playing cards, Ace to 9 only.

To play:

Deal 2 cards to each player.

Players turn over their cards and make the largest 2-digit number they can with the cards they have been dealt.

The player with the largest number scores a point.

Play ten rounds. The winner is the player with most points.

Variations

• Deal 3 cards to each player and make 3-digit numbers.
• Try 4 or 5- digit numbers.
• Get a point for the smallest number rather than the largest.
• Play more than 10 rounds.
