Groupings of 5 in numbers to 50

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:

You can help your child to practice the number of groups of 5 in numbers up to 50. For example, there are six groups of 5 in 34.

What you need:

  • Game card (PDF,56KB) . You can print these or make your own.
  • Two dice

What to do:

Give each player a game card.
The 6 is a 0, or place a sticker of the 6 and mark it as a 0.
Players take turns to roll the dice, and arrange the numbers to make a two digit number. For example, 4 and 3 can be arranged as either 34 or 43.
The player then works out how many groups of 5 are in the number and crosses the number off their game card. For example, if the player rolls a 3 and 2 they could arrange the numbers to make 23, and then cross 4 off their game board because there are 4 fives in 23.
They may use skip counting to work it out. For example, 5, 10, 15, 20 and then reason there are four 5s in 20 but one more 5 takes them over 23, so there are 4 fives in 23.
The first player to cross off all the numbers on their game board wins the game.

What to expect your child to do:

To correctly identify the number of fives in numbers up to 50.

Variation:

  • Find the number of 2s in the number.
  • Use your home language to do this activity
  • Practise asking your child questions in your home language
  • Ask about skip counting with the classroom teacher.

He Whakawhitinga Kōrero:

  • Pīroria ngā mataono tau. (Roll the die.)
  • Whakamahia ngā tau e rua hei hanga i tētahi tau mati-rua. (Use the two number to make a 2-digit number.)
  • Kua hangaia e koe te tau 23. E hia ngā rima kei roto i te 23? (You have made the number 23. How many 5’s are there in 23?)
  • Tatauria ngā rima – rima, tekau, tekau mā rima, rua tekau. (Count the 5’s. 5, 10, 15, 20.)
  • E whā ngā rima kei roto i te 23. (There are 4 fives in 23.)
  • Uhia te whā i tō papa tākaro ki tētahi porotiti. (Cover the 4 on your game board with a counter.)
  • Kua uhia katoatia ngā tau i tō papa tākaro. Ko koe te toa e kare. (All the numbers on your game board are covered. You’re the winner.)
