How can you use these dots to show a sum or difference?

Fill in the blanks to show 2 ways.

\(\underline{\hspace{1.7cm}} + \underline{\hspace{1.7cm}} = \underline{\hspace{1.7cm}}\)

\(\underline{\hspace{1.7cm}} - \underline{\hspace{1.7cm}} = \underline{\hspace{1.7cm}}\)

Materials needed:

• Number cards 2–10
• 2 dot cubes

Directions:

1. Choose a number card.
   Show 2 numbers on the dot cubes that add to make your number.
2. Can you show another way?

Partner A: Hold up some fingers on each hand.

Partner B: Fill in the blanks to show how many fingers.

\(\underline{\hspace{1.7cm}} + \underline{\hspace{1.7cm}} = \underline{\hspace{1.7cm}}\)

Switch roles and play again.

\(\underline{\hspace{1.7cm}} + \underline{\hspace{1.7cm}} = \underline{\hspace{1.7cm}}\)

\(\underline{\hspace{1.7cm}} + \underline{\hspace{1.7cm}} = \underline{\hspace{1.7cm}}\)

\(\underline{\hspace{1.7cm}} + \underline{\hspace{1.7cm}} = \underline{\hspace{1.7cm}}\)
