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. They look for connections between the numbers and types of blocks used each time. They also measure the length of the side of the square base of each carton and its height.
