Groupings of 10 and 5 in numbers to 100

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 to learn the number of groups of 10 and 5 in numbers to 100.

What you need:

  • 1 pack of playing cards (Ace = 1 Jack = 0)
  • Draw a score card for each player or print out the next page
  • Pencils

Score Card:

Number of 10s Number Number of 5s
1    
2    
3    
4    
5    
6    
7    
8    
9    

What to do:

Shuffle the cards and place them in a pile between the two players.

The first player draws two cards from the pile and makes a 2-digit number.

For example: 2 and 3 can be arranged as 23 or 32.

The player works out how many tens are in the number and then writes the number in the second column on the score card.

For example 23 would be written in the second column of the scorecard next to the 2.

The player then works out how many 5s are in the number and writes the number in the third column.

The player then works out how many 5s are in the number and writes the number in the third column.

The cards are placed at the bottom of the rule and the net player then has there turn.

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

Number of 10s Number Number of 5s
1    
2 23 4
3 32 6
4    
5    
6    
7    
8    
9    

What to expect your child to do:

  • Quickly recall the number of 10s in the number.
  • Initially they will find the number of 5s in the number by counting in fives. They should progress to quickly recalling the answer.
  • Talk about how many numbers are left over after the groups of 5 have been counted. For example: there are 4 groups of 5 in 23 and 3 left over.
