Foldables are excellent ways to organise information. They allow for different learning styles as they involve some listening, writing, drawing and hands on activity. They also allow students time to consolidate learning whilst doing the activity. They are generally very focussed tasks. During the activity the teacher is free to help students one on one and to clarify understanding. This is great because you can visibly see who needs help.
Foldables are good for slower learners due to the hands on nature of the task but bright students also like them as they make sense and they feel proud when they have completed the task.
Foldables are then an excellent revision tool. I have also allowed weaker students to bring them into a test to give some support.
Basically this activity involves two parts. Part 1 involves making a Periodic Table and goes into electron configuration and atomic theory for the first 18 elements. It can then be used to investigate ion charges. Part 2 simulates forming ionic compounds, given the ion charges.
This particular foldable is good for Year 9 or 10 students. Part A could be used in Year 8 for brighter students or if the electron configuration is ignored.
