S.H.
It ALL depends, on her dexterity and fine-motor skills. And safety.
Can she for example, glue things? Cut with scissors?
Does she mouth small objects or not?
You can use, Glue Sticks, egg cartons, pom-poms, popsicle sticks, paper plates, twigs, beads etc.
Just glue anything together.
It does not have to be a 'literal' replication of an object.
It is just for fun.
Let her just create anything.... just by gluing things together. And let HER, tell you what she made.
That promotes, creativity.
Don't for example, tell her "let's make a dog. This is how..." And do it for her. Let HER make it and glue whatever together. The best she can. It is not about how 'perfect' she does it, but that she enjoy 'creating' just stuff.
Or, cut out pictures from a magazine. Then let HER glue it on construction paper. Teach her how to use a Glue Stick.
Glue sticks, are easier, for kids to use at this age.
Again, it is not about how perfect, she replicates an object or not. It is about... promoting creativity, and letting her mind come up with something. Even if it is just whimsical or pretend or made up.
She can create, her OWN.... object.
This fosters creativity and problem-solving, too. And fun.
