You dont need a big yard to get kids excited about their first garden. Try this mini garden bed project. Encourage your kids to take ownership of their urban farm by growing what THEY want to eat adding their favourite colourful design in non-toxic paint.
Use tape on a table (place a string underneath the tape to make it tactile as a raised lined drawing) to make the shape then the child matches the block to the correct shape. could also be done on boards to work on the floor as puzzle
