Subitizing Card Games: An Exciting Way to Practice Number Recognition

Want your students to get some subitizing practice with an engaging activity? Let them go to battle with our Subitizing War card game! This activity exposes students to many different number representations, including:

• Numeral form
• Tallies
• Dice
• Ten frames
• Fingers held up

An essential element of subitizing is the instant recognition of a quantity without counting. Playing this subitizing card game reinforces this quick decision-making as students instantly decide who won each hand.

Why Teach Subitizing?

The ability to subitize is included in math learning standards because it is an important foundational skill. Here are some reasons that the time your students spend subitizing is well worth it:

• Improves Number Recognition: Subitizing helps students identify and connect numerals with quantities. This helps students transition from counting objects to recognizing numbers in different contexts.
• Sharpens Mental Math Skills: The ability to quickly and accurately recognize numbers is essential for mental calculations and problem-solving.
• Supports Addition and Subtraction: When students can quickly identify quantities, addition and subtraction are much easier to learn.
• Aids in Understanding Fractions: Recognizing that 3 out of 6 is half builds the foundation for learning future fraction concepts.
  

Instructions:

• Print and cut apart all the subitizing cards.
• Shuffle and deal the cards equally to each player.
• Players flip over their top card.
• The player with the higher amount wins the hand and the played cards.
• Play continues until one player has won all the cards and is declared the winner.
