The lesson builds on students' work measuring with standard units. This task refers to a problem presented in "How Big is a Foot" by Rolf Myller. After reading the story students will create/build beds for varying sizes of pets in customary units: inches, feet, and yards. The mathematical concepts in this lessons builds toward students' future work with the number line and finding sums and differences within 100.
