Students who are more advanced can write down the name of the shape they made. When blowing bubbles the students could also count how many bubbles they were able to make with each shape and write that number down.
ELL students could practice just making the shapes with pipe cleaners.
Students who are farther behind could work with other students in creating different shapes, but after that they could blow their own bubbles outside.
The students could also skip the bubble blowing and just create shapes with pipe cleaners and glue these on paper to create a pipe cleaner shape display.
Older students could also do this activity with more advanced shapes.
