Remember: Partners make ten, and tens partners make a hundred, so sums get quicker.

Read the story, then answer.
Fill the TrayAt the fair there was a game called Fill the Tray. Every tray had ten spots, and filling them all won a prize. Mia's first tray already had two cubes in it. To see how many more would fill it, Mia counted the empty spots. There were eight empty spots, so two cubes and eight made a full tray! Two and eight are partners, because partners make ten. With five cubes in and five spots left, five is its own partner. Ben filled his tray and won a shiny pencil.
