Once left and right feel familiar, a third word joins them: middle. This Pre-K left, middle and right worksheet lines up three pictures in each row. The first question asks what is in the middle, so the child spots the birthday cake between a snail and two tickets. Then comes the left, with a white car before a fox and an exercise bike. Finally, the right side holds a green frog. Each row trains the concept of middle as the place between two neighbors.
