木製磁鐵數字

My toddler loves sticking these to the fridge—the magnets are strong enough to hold the numbers in place while she counts.

The little wooden case keeps all 37 pieces together so we're not hunting for a missing 7 under the couch. My daughter lined up the numbers to twenty on the fridge and then started adding with the math signs on her own.

My 4-year-old actually asks to play with these, which never happens with her other toys. The pieces stick well to the fridge and the five math signs mean we can start simple addition now that she's got her numbers down.
