Children enjoy working with the land form materials. Different kinds are able to be purchased on many Montessori website that sell materials. Some teachers and homeschool families make a set of their own using small foil tin trays and hardening clay. Small booklets can be made as children color the water and land parts of each landform. Small land and water animals to use along with a landform is always a popular activity in the classroom.
More ideas and other landform samples can be found in Week 13 Day 3 and Week 13 Day 4 of the curriculum pages.
