Kat and Squirrel Story for the Lesson
Squirrel took orders around the neighborhood for lemonade including how many ice cubes each person wanted in the glass. Kat carefully counted ice cubes to match each order and filled the glasses with yummy lemonade. As Squirrel was starting to deliver the glasses her friends decided to help. Oh, no! They thought the ice cubes were nuts and took some out of each glass. Squirrel went back to the lemonade stand with the bad news. Squirrel wrote the total needed and how many cubes were left on each glass. Can you help Kat and Squirrel figure out how many ice cubes are needed in each glass?
