Groupings of numbers and their remainders

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.

Purpose:

To help your child to practice the groups of 3, 4, 6, 7, 8, 9 in numbers up to 100.

What you need:

  • Pack of playing cards. ( Ace = 1, Jack = 0)
  • Score card, paper and pencil for each player

What to do:

Each player chooses the number of groups they want to focus on (3, 4, 6, 7, 8, or 9)

Write this in the space in the first row. This number is the group number.

Shuffle the cards and place them face down between the players.

The first player draws two cards from the pile and makes a number by arranging the two digits. For example the cards 2 and 3 can be arranged as 23 or 32.

For Groups of (4)

Write 23 in the Number column beside 20-29.

Write 5 in the Groups column.

Write 3 in the Remainder column.

  Number Groups of: 4 Remainder
0 – 9      
10 - 19      
20 - 29 23 5 3

For groups of (5)

Write 23 in the Number column beside 20-29.

Write 4 in the Groups column.

Write 3 in the Remainder column.

  Number Groups of: 5 Remainder
0 – 9      
10 - 19      
20 - 29 23 4 3

The cards are placed at the bottom of the pile.

The next player takes two cards and makes a number to have q turn to fill in a row.

The winner is the first person to fill in each space on their scorecard.

What to expect your child to do:

To instantly recall the groupings of numbers up to 10 times the group number.

Variation:

  • Start with groups of 2s, 5s or 10s.
  • The game can be played a number of times with players choosing different group numbers.
