Subtraction Basic Facts

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 practice the subtraction facts to 20.

What you need:

  • Game board (PDF,93KB) . You can print these or make your own.
  • Cardboard. (Old cereal boxes are good)

What to do:

Glue the game card on to cardboard. Cut up the game cards, shuffle and place in a face down pile between the players. Give each player a game board.
Players take turns to select two cards and arrange them to make a subtraction fact. For example, 17 and 5, form the subtraction fact 17 – 5. If the answer is available on their game board they can cross it off. The cards are returned to the bottom of the pile. The cards are shuffled every now and then during the game. The winner is the first player to cross off 5 numbers on their game board.

What to expect your child to do:

Over time expect your child to instantly recall the subtraction facts to 20.

Variation:

Play until one player has crossed off 10 of the numbers on their game board.

He Whakawhitinga Kōrero:

  • Riwhiriwhia ngā kāri, ka whakatakoto ai hei putunga, ko ngā mata ki raro. (Shuffle the cards and place them face down in a pile.)
  • Tangohia ētahi kāri e rua i te putunga kāri. (Take 2 cards from the pile.)
  • Whakamahia ō kāri e rua hei hanga i tētahi tangohanga. Tangohia tētahi o ngā tau i tētahi. (Use your 2 cards to make a subtraction. Take one number away from the other.)
  • Tirohia tō papa tākaro. Kei konā te otinga o te tangohanga? Mēnā kei konā te otinga o te tangohanga, uhia ki te porotiti. (Look at your game board. Do you have the answer to the subtraction? If you have, cover it with a counter.)
  • Whakahokia ngā kāri ki raro o te putunga kāri. (Put your cards back on the bottom of the pile.)
  • Ko te mea tuatahi ki te uhi i ētahi tau e rima o te papa tākaro, ko ia te toa. (The one that is first to cover 5 numbers on the game board is the winner.)
