PreS-Gr 1—These titles resemble sections of a textbook, focusing on one concept and offering several approaches to it. In Comparing Fractions, the proverbial pizza is one example used to solve a problem and for sharing. Other examples include peppers, corn, tomatoes, radishes, and eggs. On each spread, an activity is suggested to reinforce the concept. In the second title, the basic idea of sets is introduced through familiar objects: clothing, toys, kitchen items, and body parts. The activities encourage children to search through their homes for sets and make comparisons.
