1. F A L L Measurements! by Sarah Yanes

2. Mrs. Schott’s third grade class started a math unit on measurement during the fall months. The students were assigned to bring in fall objects to measure their mass and compare their lengths. Mr. RulerMr. Beam Scale

3. Before starting the activity on Fall Measurements, Mrs. Schott reviewed with her students what the definitions of mass and length were. Mass: is the amount of physical matter that an object contains It is measured in kilograms/grams Length: is the distance from one end of something to the other It is measured in inches/feet

4. The class was randomly split into five groups of four students. Mrs. Schott set up the objects so that there was only one type of fall object at each station. The students rotated stations after about ten minutes at each one. The five objects that the students had to measure were pumpkins, leaves, acorns, pinecones, and different types of squash.

5. Measuring Pumpkins! When using the scale, the groups each measured 3 different sized pumpkins and came up with the following masses: 2,000 grams or 2 kilograms 400 grams1,105 grams The students recorded the measurements in their math journals. MASS

6. Measuring Leaves! When using a ruler, the students each measured 3 different sized leaves and came up with the following lengths: LENGTH 7 inches tall 6 inches wide 4 inches tall 5 inches wide 2 inches tall 1 1/2 inches wide

7. Measuring Acorns! When using the scale, the groups each measured 3 different sized piles of acorns and came up with the following masses: 434 grams 400 grams 415 grams MASS

8. Measuring Pinecones! When using a ruler, the students each measured 3 different sized pinecones and came up with the following lengths: LENGTH 3 1/2 inches tall 3 inches wide 4 inches tall 2 1/2 inches wide 5 inches tall 4 inches wide

9. Measuring Squash! When using the scale, the groups each measured 3 different sized squashes and came up with the following masses: MASS 500 grams 345 grams415 grams

10. After finishing up the Fall Measurement activity the students discussed what they had measured, learned, and enjoyed. Mrs. Schott’s class then turned in their math journals with their recordings and cleaned up the stations of fall objects.

11. 3rd Grade Math TEKS (3.11) Measurement. The student directly compares the attributes of length, area, weight/mass, and capacity, and uses comparative language to solve problems and answer questions. The student selects and uses standard units to describe length, area, capacity/volume, and weight/mass. The student is expected to: (A) use linear measurement tools to estimate and measure lengths using standard units; (D) identify concrete models that approximate standard units of weight/mass and use them to measure weight/mass;
