Trucks for children kids. How to make rainbow rice sensory box - in this video I show our toy construction trucks: a road roller, a front loader, a backhoe loader, and a bulldozer. Your child will hear the name of each truck and see its spelling in English. I also suggest you to make a colored rice construction site for toy trucks that you can use indoor, sunshine or rain. This is a great way to entertain toddlers and preschoolers that helps them to develop fine motor skills and speech (like other sensory activities such as play dough or clay modelling, origami, etc.)
