They also find each month the average height of all the students in the class, and discuss how the change in average height over the year is similar to, and how it is different from, the change in height over the year of the individual students in the class. Students plant some seeds in vermiculite and some in soil. They observe the plants as they grow, measuring their height each week and recording their data in tables. They examine not only how the height of each plant changes as time passes but also whether the seeds in vermiculite or soil grow faster. Experiment with approximating length, area, and volume, using informal measurement instruments.
Students measure the length of their classroom using their paces and compare their results.
They discuss what would happen if the teacher measured the room with her pace. Students use pattern blocks to cover a drawing of a dinosaur with as few blocks as they can. They record the number of blocks of each type used in a table and then discuss their results, making a frequency chart or bar graph of the total number of blocks used by each pair of students. Then they try to cover the same drawing with as many blocks as they can. They again record and discuss their results and make a graph.
