Double Numbers - Power Up!
Check out this video to find out!
Double facts are like two superhero buddies always making the same special number.
Just like wearing two shoes together or using your hands and feet, these numbers always team up to make the same number.
Double numbers are like best friends that always stick together! Look at the cute superhero tigers in the picture below.
There are two superhero tigers at the top and two at the bottom.
Growl like a tiger every time you count!
That's right! When they come together, you get four tigers. Adding the same number — like two and two — makes a double number.
Show off your superhero powers with these flashcards. Jump like a superhero every time you count!
You did a great job!
