Loud and soft, high and low, fast and slow, echoing a rhythm, naming and mixing colors, warm and cool, and tints and shades. Handwriting games are with reading.
Music starts with hearing differences: loud and soft, high and low, fast and slow, and copying a rhythm back. Art starts with color: naming it, mixing two paints to make a third, and seeing warm and cool colors, tints and shades.
Both games read their questions aloud and are made for kindergarten through 2nd grade.
Arts standards vary by state and are mostly about making and performing, which a short game can't check, so these games don't list standard codes. Think of them as a quick, playful add-on to music and art class, not a replacement.
Each game moves up a level after a strong round and back one after a tough round. Here are the levels, easiest first.
