I call this activity “Double Me Upward“. It is a simple idea indeed – the multiplication table from 1 to 12 in a stackable, rainbow-colored format.
One idea for using this set is to have kids fill in one or two charts per day, saving all the charts they complete. When all the charts are filled in, have students stack and glue them together to make 12 layers and a nice rainbow-colored 3D multiplication table that allows you to see a whole row or column of multiples in a quick glance. The structure also subtly highlights the corner number – the double! This of course is useful for learning “doubles” or squares (3×3, 4×4, 5×5, etc).
This set is completely free , easy to print, and can only be obtained through this site.
