Number (order and place value)

UK Primary (3-6)

Identifying the value of the digits in numbers (Investigation)

Lesson

What's in a name? In this activity, you'll work with a partner to practise number names.

For this activity you will need

- Two sets of ten cards numbered $0$0 to $9$9 (one for each person)
- a $6$6 sided die
- optional: a number expander (you or your teacher can print one out from here)

Take turns drawing $5$5 cards from the deck. Use those cards to make a number. (If you want you can write this number on your number expander.)

Roll the die. The number will decide how you read your number aloud to your friend.

- $1$1 or $2$2- Say how many units in your number
- $3$3 or $4$4 - Say how many tens and units in your number
- $5$5 or $6$6 - Say how many hundreds and units in your number

Your friend then uses their number cards to recreate your number.

Your friend draws a $4$4, $6$6, $2$2, and $8$8. He decides to make the number $6248$6248. If he rolls

- $1$1 or $2$2 - He says, "six thousand, two hundred plus forty-eight units."
- $3$3 or $4$4 - He says, "six hundred twenty four tens plus eight units."
- $5$5 or $6$6 - He says, "sixty-two hundreds plus forty-eight units."

1. Were there numbers that were more difficult to say than others? Why was that?

2. If you had numbers with a zero, did this make a difference to how difficult you felt the number was?

- Draw more cards
- Change the requirements for the dice rolling
