Naming Number Dominoes

Naming Numbers Dominoes
Play dominoes with your partner or group by matching the numbers with the words.
Who will be first to use all their dominoes?

Beat the Teacher 1

Beat the Teacher
The aim of this game is to create the smallest number.
We will take turns to roll the dice, and decide where to
place the digits shown on the dice in the grid below.
I will go first, then I will choose someone
from our class to have a turn.
Think carefully about where to place the digits
to create the smallest number.

Now we will play again, but this time we will have a different aim!

Spotting Mistakes

Spotting Mistakes
The year 6 class at Anywhere School have been learning about number and place value. They have answered some questions, but their teacher is confused by their answers.
Five hundred and fifty thousand, six hundred and three is written
5563 in digits.
Sam has forgotten to put a zero in the thousands place and in the tens place
The number should be 550 603.
Can you spot their mistakes? Explain what each person did wrong and how they could correct their answers.
Reveal mistake

Spotting Mistakes
Mischa has got mixed up when comparing the place value of the different digits in these decimal numbers. In 23.64, the tenths digit
is 6. In 26.9, the tenths digit is 9.
9 is higher than 6.
Can you spot their mistakes? Explain what each person did wrong and how they could correct their answers.
Reveal mistake
The value of the tenths digit in 23.64 is higher than than the value of the tenths digit in 26.9.

Spotting Mistakes
Robert has forgotten that the value of the digits gets smaller the further to the right of the decimal point they are. He may also have got mixed up with tens and hundreds. Two tenths is bigger than two hundredths!
Can you spot their mistakes? Explain what each person did wrong and how they could correct their answers.
Reveal mistake
Tenths are bigger than hundredths,
so 0.2 is smaller than 0.02.

Spotting Mistakes
Olivia has got mixed up with the place value of each digit in this number.
The digit in the ten thousands place
is actually 2.
Can you spot their mistakes? Explain what each person did wrong and how they could correct their answers.
Reveal mistake
In the number 2 220 002, the digit in the ten thousands place is zero.

Spotting Mistakes
Sean has not compared the value of just the thousandths digit in each number. He has compared the overall value of the decimal fraction of each number. The thousandths digit in 19.042 is 2, while the thousandths digit in 3.991 is 1. As we know, 2 is actually higher then 1!
Can you spot their mistakes? Explain what each person did wrong and how they could correct their answers.
Reveal mistake
The value of the thousandths digit in 19.042 is lower than then the value of the thousandths digit in 3.991.

Now we will play again, but this time we will have a different aim!

Number Rules

Number Rules
I am thinking of a rule about numbers. It might be 'numbers with a
5 in the hundredths place' or 'numbers higher than 10 000'.
Can you work out the rule I am thinking of?
I will ask the people who have written a
number that follows the rule to stand up,
holding their boards so everyone else can
see their numbers.
Look around at the numbers.
Can you spot the rule?
What do all the numbers have in common?
Try to write a number that you think fits the rule.
We will repeat this until everyone has a number
that fits the rule!
Write a number on your whiteboard and hold it up.

Find Your Partner

Find Your Partner
I am going to give each person a card. On your card you will have
either three terms from a sequence, or a sequence with three missing terms.
Your task is to find your partner to match the sequence with the correct terms.
Can you move around the classroom to find your partner?
Be careful!
The terms on the
cards might not
be in order.

Get in Line

Get in Line
Each person has a number card.
Your whole class challenge is to stand in a line so that all your numbers are in order from smallest to biggest!
You can show your number card to others, but you are not allowed to talk.

Dice Dilemma

Dice Dilemma
On your Dice Dilemma Activity Sheet, you will see several blank number comparisons like this one:
You need to work with a partner to roll a dice to
make each number comparison true.
Think carefully about where you place each digit
as you roll the dice.

Fraction Action

Fraction Action
Each person in your group has a fraction card.
Unfortunately the fractions are mixed up!
You need to rearrange your group so that the fractions are in order.
Take care: some of the fractions have different denominators. You will need to convert them to equivalent fractions so that they all have the same denominator.

Numbers in Words

Numbers in Words
Can you solve these calculations using words?
What is six thousand less than one million?
Nine hundred and ninety-four thousand.
What is fifteen less than ten million?
Nine million, nine hundred and ninety-nine thousand, nine hundred and eighty-five.
What is five hundred less than five hundred thousand?
Four hundred and ninety-nine thousand, five hundred.
What is thirty thousand less than three million?
Two million, nine hundred and seventy thousand.

Magic Negatives
Can you complete the magic squares on the Magic Negatives
Activity Sheet so that the totals of each row, column and diagonal are equal? You can use negative numbers and you can use each number more than once.

Negative Number Line Loop Cards

Negative Number Line Loop Cards
On the left side of your loop card, you will see two number lines. Each number line has an arrow pointing to it. Work out the number each arrow
is pointing to and the difference between the
two numbers.
On the right side of your loop card, you will see
a difference.
I will choose one person to stand up and read out their difference. If the difference shown on your number lines matches this, stand up! Then, read out your difference.
Can you get all the way round the class, matching the differences shown on the number lines?
