This is a table to print for your home classroom. If there isn’t space to print it, you can keep a collection of interesting charts in a folder for your child to browse at will.
We display it in the 3-6 and 6 + classrooms. At these ages, children are eager to learn about new words and concepts, so we introduce them prior to actual work with the material.
The US National Library of Medicine also has a game that older children will find fun.
This is nice! The electron configurations are listed. Each row fills another layer of electrons. Much of chemistry follows from that. Other charts are more complicated (e.g. semi-metals and alkali earths) and require unneeded explanation. This chart shows is a large, but bite sized, concept. There are elements and they have patterns that can be described in a precisely ordered way using the number of electrons.
