The Ministry is migrating nzmaths content to Tāhurangi.           
Relevant and up-to-date teaching resources are being moved to Tāhūrangi (tahurangi.education.govt.nz). 
When all identified resources have been successfully moved, this website will close. We expect this to be in June 2024. 
e-ako maths, e-ako Pāngarau, and e-ako PLD 360 will continue to be available.

Purpose:

To help your child practice ordering numbers to 100.

What you need:

  • A pack of playing cards. (Ace = 1, Jack = 0)
  • Paper and pencil to keep score.

What to do:

Place the cards in a pile face down between the players.

Each player selects two cards and arranges them to make the largest two digit number. 

For example 5 and 2 can be arranged as 52 or 25.

Ask your child to read the numbers and decide which is biggest.

The player with the largest number wins a point. The winner is the first player to win 5 points. The cards are placed at the bottom of the pile.

What to expect your child to do:

To read the two digit numbers and recognise the biggest number.

Variation:

  • The aim can be to make the smallest two digit number.
  • Ask your child: How many tens are in each number? Which number is closest to 50?

He Kupu Māori:

biggest nui rawa
smallest iti rawa
pack of cards pūkei kāri

He Whakawhitinga Kōrero:

  • Whakaputua te pūkei kāri, ko ngā mata ki raro. (Place the pack of cards face down.)
  • Tangohia kia rua ngā kāri. (Take two cards.)
  • Whakamahia ō kāri hei hanga i te tau nui rawa e taea ana. (Use your cards to make the biggest number you can.)
  • Pānuihia mai ngā tau. (Read the numbers.)
  • Ko tēhea te tau nui rawa o ēnei? (Which of these two numbers is the biggest?)
  • Kotahi te whiwhinga ki a koe nā te mea i a koe te tau nui rawa. (You get one point because you had the biggest number.)
  • Whakamahia ō kāri hei hanga i te tau iti rawa atu e taea ana. (Use your two cards to make the smallest number possible)
  • E hia ngā tekau kei roto i tēnā tau? (How many tens are there in that number?)
  • Ko tēhea te tau e tino pātata ana ki te rima tekau? (Which number is closest to 50?)
