Chapter 10 gives an overview of "Time & Measurement". Students will learn the difference between A.M. and P.M. Noon is 12:00 (P.M.) and midnight is 12:00 (A.M.) The students will practice finding elapsed time (the amount of time--minutes and hours, that passes from the beginning to the end of an activity). They will also learn the different measurements of mass and liquid capacity. Mass (weight) is measured in grams and kilograms (1,000 grams), while liquid volume is measured in liters (L). Students will also practice measuring length in inches (in) and centimeters (cm), to the nearest quarter in/cm (0, 1/4, 1/2, 3/4, 1).
