Why Cotton and Sponge Compare works

At its simplest, Cotton and Sponge Compare is about careful sensory comparison, starting with the instruction to hold the cotton or cotton pad. Compare cotton and sponge through softness, springiness and how each changes when gently squeezed. The first useful comparison appears when the child then has to hold the sponge.

Set up — Hold the cotton or cotton pad

Prepare household items before the child is asked to hold the cotton or cotton pad. Complete the opening request to hold the cotton or cotton pad once before adding the next instruction to hold the sponge. Use clean, non-toxic, age-appropriate materials and stop with any irritation or discomfort throughout that first transition.

Step 2 — Hold the sponge

Treat the attempt to hold the sponge as a checkpoint between the earlier step to hold the cotton or cotton pad and the coming step to press each gently. A perfect answer is not required.

Step 3 — Press each gently

After completing the instruction to press each gently, pause and ask what changed from the earlier step where they had to hold the sponge. Use that answer to decide whether they are ready to release and watch which returns shape more clearly.

Step 4 — Release and watch which returns shape more clearly

Keep the adult prompt brief while the child tries to release and watch which returns shape more clearly. If needed, return to the earlier step to press each gently before asking them to describe how the two textures differ.

Step 5 — Describe how the two textures differ

Keep the pace slow while the child tries to describe how the two textures differ. If the effect is hard to see, simplify that action before continuing with the instruction to describe how the two textures differ.

What to notice before Describe how the two textures differ

The strongest evidence appears after the child has tried to press each gently and before they finish by trying to describe how the two textures differ. Look for which texture, sound, pressure, or material difference is actually noticeable rather than judging the round by speed or neatness.

Make Press each gently easier or harder

Use the child’s last successful attempt to press each gently to set the next round. Simplify by doing this: use two clearly contrasting materials. Extend it by doing this: compare subtler examples while keeping the handling method the same.

Finish after Describe how the two textures differ

Finish on the clear result that comes from asking the child to describe how the two textures differ. If they understand how it follows from press each gently, the activity has done enough; use the activity search or activity generator next.
