This overview shows the different parts of the library and their uses. Ants Go Marching Kindergarteners develop number sense by exploring number concepts and number relationships. The number sequence is emphasized and the distinction is made between cardinal and ordinal meanings for number. Activities include measuring with Unifix cubes and using base-ten blocks. A grade 1-2 class, working in groups, develops their sense of larger numbers by estimating and counting the number of seeds in pumpkins.
Students debate and justify their estimates verbally and in writing.
By creating patterns, children develop an early understanding of geometry. Teams use everyday language and experiences to connect to the mathematical language and symbolism for operations. They develop mathematical communication as they represent mathematical ideas with physical materials, words, diagrams, and symbols. Marshmallows Second-graders create and discuss a bar graph based on the number of marshmallows they estimate each person in their class would eat on a camping trip. After discussing their results, students determine how many bags of marshmallows to take.
