Sketch each girl’s tiles.

Drag the tiles out of the box in the eTool below to indicate how many each girl has.

If the girls put their tiles together, how many of each type of tile will they have? Write an expression that represents this sum.

Once you have moved all the tiles that Daisy and Alexandra have out of the box, count how many of each type of tile in order to combine like terms into a simplified expression.
