My first grade teachers are working on numbers from 100 to 120, and they wanted a workstation that would encourage students to think flexibly about numbers--helping them to realize that numbers can be decomposed in ways other than along traditional place value lines. This activity takes students through the concrete (manipulatives), representational (pictorial), and abstract (numerals and symbols) stages of learning. Students record their work in their math journals. All you need for this workstation is the instruction card, base-10 blocks, and some number cards.
Friendly Frogs set is just one of many themes!
