This classroom is set up amazingly well. You can see that it is themed, without being frumpy. It is cohesive, yet divided. Each area has its own space. You can easily see that the music area is just the music area. A well set up classroom will have minimal open space to discourage running/rough/'outside' play. Kudoos to this set up!
Do your kids love reading about construction? Let them "build" with toy hammers, golf tees, and foam blocks. Check out Good Night, Good Night Construction Site (j E RINKER) or Alphabet Under Construction (j E FLEMING) for a fun tie-in!
