I made my own modifications on this Montessori activity as the real learning aids were too costly. A set of Ikea colourful plastic cups (no cost, had them at home for years), a pack of coloured popsticle sticks for HK$5 from stationery shop.
Activities :
1. sort the tray of sticks into the correct cup (as shown in photo.
2. take out only 1 cup and ask child to pick out the same colour sticks from the tray.
