The cumulative progress indicators for grade 4 appear below in boldface type. Reproduce, extend, create, and describe patterns and sequences using a variety of materials. Students make a pattern book that shows examples of patterns in the world around them. Students use pattern blocks, attribute blocks, cubes, links, buttons, beans, toothpicks, counters, crayons, magic markers, leaves, and other objects to create and extend patterns. They might describe a pattern involving the number of holes in buttons, the number of sides in a geometric figure, the shape or the thickness of objects.
Students use sequences of letters or numbers to identify the patterns they have created.
Students investigate the sum of the dots on opposite faces of an ordinary die and find they always add up to 7. Students solve twodimensional attribute block patterns where, for instance, each column is a different shape and each row is a different color. They should be able to choose the block that fills in the missing cell in such patterns. Students begin with a number less than 10, double it, and repeat the doubling at least five times. They record the results of each doubling in a table and summarize their observations in a sentence.
