What can I use instead of paper cups?

Use small lightweight containers that can be taped upright inside the larger bin. The target should stay open and visible after a foil rock lands nearby.

How close should the toss line be?

Start close enough that most throws land in the container. Move back only if your child is still squeezing the foil safely and enjoying the target challenge.

Is aluminum foil safe for this activity?

Use close supervision, remove torn scraps right away, and pause if foil goes near your child's mouth. Choose another activity if your child mouths foil or dislikes the scratchy texture.

Setup

Then start the loop

Step 01

Inside the plastic container, tape 2 small paper cups firmly upright with a little space between them.

Step 02

On the floor, place the container with open space in front of it for tossing.

Step 03

Beside the toss spot, place 4 to 8 loose foil squares, about 12 inches per side.

Step 04

On the floor a little way back from the container, point out or mark 1 simple toss line.

Step 05

Behind the toss line, stand or sit your child facing the cup targets.

Step 06

Before play starts, squeeze 1 foil square into a tight ball and check that no sharp foil edges are sticking out.

"Squeeze, squeeze, toss."

The loop

How play unfolds.

Three-step sequence showing foil crumpling, standing behind the toss line, and tossing toward taped cup targets.

01
Crumple one foil square into a tight ball where your child can watch.
02
Say, "Make a tight foil rock, then toss it from behind this line."
03
Let your child squeeze one foil square with two hands until it becomes a dense ball.
04
Have your child stand behind the line and toss the foil rock toward a cup.
05
Count one throw as a complete turn, even if it misses.
06
Hand over the next foil square, or retrieve the tossed ball, and repeat the crumple-and-toss turn.

Safety Check

Supervise closely during the full activity.
Make sure foil pieces are crumpled tightly into balls before handling so sharp edges are not left exposed.
Remind your child to stay behind the toss line during play.
Remove torn scraps right away before they become mouthing hazards.

What to say in the moment

Match what you say to what you see.

Prompt ladder

Level 1 (Start)

Make 1 tight foil rock and toss it toward a cup.

Level 2 (Keep going)

Pick the next square and squeeze it even smaller.

Level 3 (Stretch)

Aim for the other cup this time.

Level 4 (Extend)

Try 1 throw from a new angle while your feet stay behind the line.

If your child seems...

What you'd see

Focused

What to do

Say

"You are squeezing it smaller."

Add

Ask for 1 cup choice before the toss.

Extend

Alternate cup targets for the next 2 rocks.

Make it easier

Younger end

-Pre-start the first squeeze so your child only has to finish tightening the foil.
-Use the larger container as the target for 1 round before returning to cup aiming.
-Let your child toss from a seated or kneeling position if standing still is hard.

Make it harder

Older end

+Ask your child to choose left cup or right cup before squeezing the foil.
+Try a gentle underhand toss, then a gentle overhand toss.
+Keep score for 3 rocks only, then reset back to free play.

If it's not working

If you see

If child ignores it

Make 1 loud crinkly foil rock yourself and toss it into the container so your child can hear and see the goal.

If you see

If child misuses it

Give only 1 foil square at a time and repeat, "Crumple first, then toss."

If you see

If child gets frustrated

Move the toss line closer or count a container hit as the goal before aiming for the cups again.

Skill spotlight

Two-Hand Coordination`

Using 2 hands to make 1 tight object.

This helps both hands work together for everyday jobs like coloring, pulling, fastening, and handling small objects with control.

•Squeezing the foil with two hands gives your child repeated practice making one tight object.
•Tossing from the line adds a simple aim-and-release target without turning the game into a long lesson.
•The cup targets and container make misses easy to see, reset, and try again.
