SE T3.01Nesting Cups
The child fits three graded cups inside each other from largest to smallest and takes them apart again.
Safety
- The smallest cup must not fit the small parts test cylinder (1.25 in. × 2.25 in.).
- Use wood, metal, or sturdy plastic cups, not glass or ceramic, and check for cracks and sharp edges before use.
Presentation
- 1
Invite the child to a low table or a floor mat and sit beside them.
- 2
Take the nested cups out of the basket and separate them slowly, one at a time, placing them in a random row.
- 3
Pick up the largest cup and place it in front of you.
- 4
Pick up the middle cup, look at both cups, and lower it into the largest.
- 5
Pick up the smallest cup and lower it into the middle one. Point of interest: each cup dropping inside the next.
- 6
Take the cups apart again and offer them to the child. Let them try without correcting.
- 7
If the child pushes a larger cup onto a smaller one and stays stuck, wait. If they look to you, place the cups side by side and say only, "Try another."
Extensions, easiest to hardest
- Five cups instead of three
- Turn the cups upside down and stack them into a tower, largest at the bottom
- Hide an object under the largest cup for the child to find, using an object too large for the small parts test cylinder
Control of error
A cup that is too large does not go inside the next one; if the order is wrong, a cup is left over at the end.
Ready to move on when the child…
- Nests three cups in order without help
- Tries a different cup when one does not fit, without looking to the adult
- Nests five cups
- Stacks the cups upside down in a tower from largest to smallest
