# Games for Number

(Multiplication – array model)

Growth Point 3 and 4)

What You Will Need?

3 players

1 Pack of numeral cards (1-9) or a 9 sided die.

Counters

How Do You Play?

2 players draw one card each.

Without looking at the card each player needs to hold the card to his or her forehead.

Player 3 multiplies the two numbers together and makes an array to represent the total.

Player 1 and player 2 need to identify what the number on their card is.

Variation:

6 sided die.

Multiples of 2, 5 and 10 only.

Partial modeling of the array

No modeling – player 3 writes the answer only on a white boards.

Record on number line.

Identify turn around facts – multiplication and division.

Write a word problem.

2-MINUTE CHALLENGE

What You Will Need?

2 Players

Counters

Die

Timer

How Do You Play?

Player 1 rolls the die and player 2 makes a collection using the counters.

Player 2 rolls the die and player 1 makes a collection using the counters.

This continues for 1 minute.

After one minute each player needs to count the total amount of counters in his or her collection.

Record total count on a bead string, white board, post-it-note or number line.

Each player proves their total without counting by ones – aiming to group their counters in the easiest way to count them.

Variation:

Use a place value chart and group the collection in tens and ones.

Record each count on an empty number line/tape measure.

Compare smaller/larger numbers on an empty number line/tape measure.

Numbers closest to the next decade.

Difference between player 1 and player 2 count – I have 15 more/less counters.

Start with a collection of 50/100 and take away the number of counters indicated by the die.

TUG-O-WAR

What You Will Need?

2 players

1 die/Numeral Cards.

How Do You Play?

Choose the total number of beads to play with.

Each player starts with half this number beads at their end of the bead string.

E.G. if 30 was the starting number each player would have 15 beads.

Player one rolls the die/turns the next digit card over and takes that number of beads from the other player.

If a 4 is rolled ….

Each player must say

– I now have 19 beads and you have 11.

A player wins when the other player has no beads left.

Encourage the students not to count by ones.

How many groups of ten do you have?

How many more/less beads do you have compared to the other player?

How many more do you need to win?

Variation:

Use only 10 beads and one die marked 1 – 4.

Use two dice – add the scores together or move the difference between the dice.

PLACE VALUE

What You Will Need?

2 Players

Hundreds Place Value Board

Die

Elastic Bands

Sandwich Bag

How Do You Play?

Players take it in turns to roll the die – they collect that number of paddle pop sticks.

The paddle pop sticks are put on the place value chart.

When a player has ten paddle pop sticks they bundle them together and place an elastic band around them.

The bundle is than placed under the tens column on the place value chart.

When they have ten bundles – they are bundled together and placed into a sandwich bag, which is then placed under the 100s column on the place value chart.

When a player has reached one hundred they are the winner.

How many groups of ten do you have altogether?

How many more do you need to make your next group of ten?

How many will you have if you had ten less.

How many more do you need to make 100?

Variations:

Use a place value chart with 1000s.

Start with a collection of 100 – and subtract with each roll of the die. Play the game backwards

– subtraction.

Use a decimal place value chart – building up tenths until a whole number is reached.

Record numbers after each roll of the die using expanded notation.
