Piano time signatures: 4/4, 3/8 and 6/8
A time signature tells you how a measure is organized. In 4/4, a measure holds four quarter-note units. In 3/8, it holds three eighth-note units. In 6/8, it holds six eighth-note units, normally grouped as two beats of three. It does not tell you how many noteheads must appear.

Read the two numbers together
The top number counts units per measure. The bottom identifies the unit: 4 means a quarter note and 8 an eighth note. Long notes, rests and tied notes can fill those units in different ways. A chord has several pitches sounding together; counting its noteheads does not give the beat count.
Hear 4/4 in a first melody
Our Mary Had a Little Lamb arrangement is in 4/4. Count 1, 2, 3, 4 evenly while the melody moves or holds. Its final C lasts a full measure. Our Jingle Bells arrangement also uses 4/4, but contains a different rhythm.
Feel the groups in 3/8 and 6/8
Our Fur Elise opening-theme excerpt uses 3/8. Count three eighth-note units when starting slowly. Our Row, Row, Row Your Boat arrangement uses 6/8: count 1-2-3, 4-5-6, with a stronger feel on 1 and 4. At a flowing tempo, those two groups often feel like two larger beats. Tempo and phrase shape still matter.
